12mm SMD Tact Switch 4 Pin — TS-1103S 180gf / 260gf Large Body Surface Mount Tactile Pushbutton for Home Appliances, Automotive & Industrial PCB
12mm SMD Tact Switch 4 Pin — TS-1103S Product Overview
The TS-1103S is a 12mm SMD tact switch 4 pin — a large-body surface-mount momentary tactile pushbutton switch designed for PCB applications where a larger actuator surface, higher actuation force, and prominent panel presence are required. Manufactured by Vistar Electronics, the TS-1103S fills the space between compact 6×6mm signal-level tact switches and full-size panel-mount push buttons — providing the SMT assembly convenience of a surface-mount tactile switch in a 12mm body that can be operated reliably by operators wearing gloves, using tools, or working in conditions where precise fingertip targeting of a small button is not practical.
The TS-1103S surface mount tactile switch large body measures 12mm × 12mm — four times the footprint of a standard 6×6mm SMD tact switch. This larger body provides three key advantages for the target applications: (1) a significantly larger actuator cap surface that can be pressed from a wider range of approach angles, (2) a more robust PCB mounting with four SMT leads distributed across a wider span for greater pull-out resistance and stability under operating force, and (3) a more prominent visual indicator of button position on control panels — making it easy for operators to identify and target the switch without precision fingertip placement.
The TS-1103S is available in two configurations that address different application requirements:
- 180gf / 50,000 cycles — standard configuration for home appliances, consumer electronics, and light commercial equipment where moderate actuation force and standard commercial cycle life are sufficient. The 180gf force provides a firm, deliberate press that prevents accidental actuation while remaining comfortable for frequent daily use.
- 260gf / 100,000 cycles — heavy-duty configuration for automotive controls, industrial operator panels, and equipment subject to high-cycle daily operation. The 260gf force requires a clear, intentional button press — ideal for safety-critical controls where accidental activation from vibration or incidental contact must be prevented. The 100,000-cycle rating provides approximately twice the service life of the standard variant.
According to the IEC 61058-1 standard for switches for appliances, tactile switches in home appliances and consumer electronics are classified by their rated current, voltage, mechanical cycle life, and environmental conditions. The TS-1103S 180gf / 50,000-cycle variant meets commercial-grade requirements for home appliance controls; the 260gf / 100,000-cycle variant meets the higher-grade requirements of light-industrial and automotive interior applications.
The 12mm SMT pushbutton 180gf 260gf PCB configuration of the TS-1103S uses four symmetrical gull-wing SMT leads compatible with automated pick-and-place assembly from tape-and-reel packaging and standard lead-free reflow soldering. The PA66 UL94 V-0 rated body withstands standard reflow temperature profiles. This allows the TS-1103S to be assembled in the same SMT production pass as other surface-mount components — no secondary DIP through-hole soldering or hand assembly step is required, keeping production costs low for home appliance and consumer electronics volume production.

Why Engineers Specify the TS-1103S Large Body SMD Tactile Switch 100,000 Cycles for Appliance & Industrial Controls
12mm Large Body — 4× Bigger Actuator Surface than 6×6mm
The 12mm × 12mm body provides four times the actuator surface area of a standard 6×6mm SMD tact switch. This larger target makes the TS-1103S the right choice for controls operated by users wearing work gloves, rubber-tipped tools, or stylus inputs — covering home appliance front-panel buttons, industrial machine controls, and automotive overhead console switches where accurate small-button targeting is not practical during operation.
Two Force Options — 180gf for Consumer, 260gf for Industrial
The 180gf variant provides a firm, comfortable press for daily-use consumer electronics and home appliances — positive enough to prevent accidental activation but not fatiguing for repeated use. The 260gf variant requires a clear, deliberate button press — the appropriate choice for automotive controls, industrial safety-critical panels, and outdoor equipment where vibration or accidental contact must not trigger the switch. Specify the force variant that matches your application’s safety and usability requirements.
Up to 100,000 Cycles — Industrial & Automotive Grade Durability
The 260gf configuration is rated for 100,000 mechanical actuation cycles — the standard threshold for automotive interior controls and light-industrial equipment rated for a 10-year service life with daily use. The 180gf configuration provides 50,000 cycles — appropriate for home appliance controls used less intensively. Both variants maintain consistent actuation force and contact resistance throughout their rated cycle life.
SMT Gull-Wing Leads — Automated Pick-and-Place Assembly
Four symmetrical gull-wing SMT leads allow automated pick-and-place placement directly from tape-and-reel. The UL94 V-0 rated PA66 body withstands standard lead-free reflow profiles (peak ≤260°C), enabling the TS-1103S to be assembled in the same SMT reflow pass as all other components — no secondary through-hole soldering or hand assembly step required, keeping production cost low for appliance and consumer electronics volume manufacturing.
Drop-In Compatible with 12mm Through-Hole Tact Switch Footprints
The TS-1103S SMD configuration is designed to be footprint-compatible with the 12mm body size used across many existing PCB layouts in home appliances and consumer electronics. Engineers migrating from DIP through-hole 12mm tact switches to SMT production can adopt the TS-1103S as a direct package-change substitute, gaining the production cost benefits of SMT assembly without requiring a new PCB layout for the switch position.
RoHS 3 & REACH Compliant — Global Consumer Electronics Export Ready
Fully compliant with RoHS 3 (EU Directive 2015/863) and REACH SVHC substance regulations — essential for home appliances, consumer electronics, and automotive components sold in the EU, UK, and other regulated markets. RoHS declarations of conformity and REACH SVHC substance statements available on request for CE marking, supply chain qualification, and customer audit documentation.

TS-1103S 12mm SMD Tact Switch — Frequently Asked Questions
What is the difference between the 180gf and 260gf variants of the TS-1103S?
The two variants differ in actuation force and rated cycle life — both have the same 12mm body, 4-pin SMD footprint, and 50mA/12V DC electrical rating:
- 180gf / 50,000 cycles: moderate firm press — suitable for home appliances, office equipment, and consumer electronics where users interact with controls daily but at moderate intensity. 50,000 cycles equates to approximately 27 presses per day for 5 years.
- 260gf / 100,000 cycles: heavy deliberate press — suitable for automotive controls, industrial operator panels, and equipment where accidental activation from vibration or incidental contact must be prevented. 100,000 cycles equates to approximately 27 presses per day for 10 years, or higher frequency in industrial environments with shorter expected equipment lifespan.
Choose 180gf for consumer and light commercial applications; choose 260gf for automotive, industrial, and safety-critical applications. Both variants are available in the same tape-and-reel packaging format with the same PCB footprint.
How does the 12mm TS-1103S differ from the 6×6mm TS-1102S tact switch?
The TS-1103S (12mm) and TS-1102S (6×6mm) are both 4-pin SMD momentary tact switches with the same 50mA/12V DC rating, but differ significantly in body size, actuator surface, and force range:
- Body size: TS-1103S is 12×12mm — four times larger than the TS-1102S 6×6mm footprint. The larger body occupies more PCB area but provides a significantly larger actuator surface.
- Actuator surface: the 12mm actuator can be pressed by fingertips, gloved hands, or tools from a wide range of approach angles. The 6mm actuator requires more precise fingertip targeting.
- Force range: TS-1103S is available in 180gf and 260gf — heavier forces suited to panels where accidental activation is a concern. TS-1102S is typically specified at 100–160gf for lighter consumer-grade interaction.
- Applications: TS-1103S for front-panel appliance controls and industrial HMI; TS-1102S for compact consumer electronics and IoT device user interfaces.
Can the TS-1103S be used in automotive interior applications?
The TS-1103S 260gf / 100,000-cycle variant is well-suited for automotive interior control applications where the switch is not exposed to the engine bay, underbonnet temperatures, or direct external weather. The −25°C to +70°C operating range covers automotive interior temperature extremes (from a cold arctic start to a hot parked interior in direct sunlight).
For automotive-grade components requiring AEC-Q200 qualification, extended temperature ranges (−40°C to +125°C), or formal automotive part approval (PPAP), consult our engineering team regarding appropriate component selection and qualification documentation. The TS-1103S is a commercial-grade component appropriate for interior cabin controls, not under-hood or exterior applications.
What PCB footprint (land pattern) does the TS-1103S require?
The TS-1103S uses a 4-pin symmetrical gull-wing SMD footprint with the 12mm × 12mm body outline. The precise pad dimensions, pitch, courtyard, and reference designator placement are specified in the product datasheet. Contact sales@vistarelectronics.com to request the TS-1103S datasheet with full land pattern dimensions for your PCB layout.
The TS-1103S footprint is designed to be compatible with the standard 12mm tactile switch land pattern used across many existing PCB designs for home appliances and industrial controls — engineers with an existing 12mm tact switch footprint should verify specific pad dimensions against the datasheet before substituting the TS-1103S.
Does the TS-1103S include a cap or actuator cover for colour coding?
The standard TS-1103S includes a flat thermoplastic actuator cap in the standard body colour. For panel designs requiring colour-coded button caps (red for stop/power off, green for start/on, yellow for caution, etc.) — a range of coloured snap-on cap accessories compatible with the 12mm body size are available separately.
Contact our sales team to enquire about cap colour options and availability for the TS-1103S body size. Custom coloured caps can be supplied for OEM production orders meeting minimum quantity requirements.
What is the MOQ and can I get a free sample?
Standard MOQ is 1,000 pieces per variant (180gf and 260gf are ordered separately). Production lead time is 2–4 weeks. Free samples of both the 180gf and 260gf variants are available for qualified engineering and product development projects — allowing you to evaluate both actuation forces in your actual product before committing to production quantities.
