4 Pin Tact Switch SMD 6.2mm — Compact Surface Mount Tactile Switch for High-Density PCB Designs
4 pin tact switch SMD solutions deliver reliable momentary contact in ultra-compact footprints. The TS-1157 is a 6.2mm × 6.2mm surface mount tactile switch featuring 4-pin SMD termination, dual operating force options (180gf/260gf), and mechanical life up to 100,000 cycles. Designed for automated PCB assembly, this mini tactile switch is ideal for consumer electronics, medical instruments, industrial HMI panels, and portable devices where space and reliability are critical.
Product Overview of SMD Tactile Switch 6.2mm
The TS-1157 is a high-reliability 4 Pin tact switch SMD 6.2mm designed for modern electronic products requiring compact input interfaces. With a standard 6×6mm footprint and 4-pin surface mount configuration, this switch occupies minimal PCB real estate while providing stable electrical contact and crisp tactile feedback. The 6.2mm body size aligns with industry-standard tact switch dimensions, ensuring compatibility with existing enclosure cutouts and silicone keycap designs.
Engineered for surface mount technology (SMT) assembly lines, the TS-1157 ships in tape-and-reel packaging compatible with high-speed pick-and-place equipment. This reduces manual insertion labor and improves placement accuracy in high-volume manufacturing environments. The switch supports a rated load of 50mA at 12V DC, making it suitable for low-power signal switching in digital circuits, microcontroller reset inputs, and menu navigation buttons.
Users can select between two operating force variants—180gf for light-touch applications such as remote controls and wearable devices, or 260gf for industrial equipment where positive actuation feedback prevents accidental triggering. The 0.2±0.10mm travel distance ensures rapid response with minimal key wobble, while the robust internal dome structure delivers consistent performance across the entire operating temperature range. For comprehensive background on tactile switch technology and industry standards, refer to the Wikipedia Tactile Switch Guide.
The TS-1157 uses the industry-standard 6×6mm SMD footprint —
the most widely specified tactile switch footprint in consumer and industrial
electronics. At 6.2mm body width, it is a direct drop-in replacement for
existing 6×6 tact switch positions without PCB redesign. Unlike the
TS-1102SW waterproof variant which adds IP67 sealing at a higher cost,
the TS-1157 is the cost-optimised choice for standard indoor PCB applications
where waterproofing is not required. Unlike the
TS-1103S 12mm large-body variant, the TS-1157’s compact footprint suits
high-density PCB layouts where multiple buttons must fit in a limited panel area.

Key Features of Mini Tactile Switch TS-1157
Ultra-Compact 6×6mm SMD Footprint
The mini tactile switch body measures just 6.2mm square, freeing valuable PCB space in portable electronics, wearables, and high-density control boards where every millimeter counts.
Dual Operating Force Options
Choose 180gf for soft, quiet actuation in consumer remotes and medical devices, or 260gf for firm, definitive feedback in industrial machinery and outdoor equipment where accidental presses must be eliminated.
Extended 100,000-Cycle Mechanical Life
The high-durability dome contact system achieves up to 100,000 actuation cycles, ensuring years of reliable service in products with frequent daily use such as security keypads and handheld instruments.
Precise 0.2mm Short Travel
The minimal 0.2±0.10mm travel distance delivers rapid actuation and fast return, reducing operator fatigue and enabling high-speed data entry in barcode scanners and test equipment.
Reel Packaging for Automated Assembly
Tape-and-reel packaging supports high-speed SMT lines, while bulk bag options accommodate prototype runs and manual assembly. Both formats minimize component damage during shipping and handling.
RoHS & REACH Compliant
Lead-free contacts and halogen-free housing materials meet global environmental directives, ensuring unrestricted market access for OEM and export-bound products.
