Tact Membrane Switch 2.63 0.65 — TS-2630 SMD Membrane Tactile Switch for Industrial Control, Medical Devices & Consumer Panels

The TS-2630 tact membrane switch is a surface‑mount tactile switch designed with an integrated membrane overlay, offering a wide 2.63‑inch by 0.65‑inch rectangular actuation zone. This large footprint makes it exceptionally easy to integrate into front panels, industrial control keypads, medical device interfaces, and consumer appliance consoles. Unlike conventional small tactile switches, this tact membrane switch 2.63 0.65 provides a generous target area for finger press, while maintaining a crisp, tactile snap and reliable electrical contact closure.

The switch combines a stainless steel dome contact with a sealed polyester membrane layer, providing both tactile feedback and environmental protection. The SMD terminals allow direct reflow soldering to the PCB, eliminating the need for through‑hole drilling or hand wiring. With a mechanical life of 500,000 cycles and gold‑plated contacts, the TS-2630 delivers consistent performance over years of continuous use. The membrane overlay can be customized with graphic legends, making it suitable for branded control panels and user‑interface buttons that require clear identification.

Engineers will appreciate the switch’s low profile of just 3.5mm total height above the PCB, which fits within thin enclosures. The large actuation surface also simplifies mechanical integration with external plungers or button caps. This membrane tact switch 2.63 x 0.65 is a go‑to solution for both prototyping and high‑volume production.

Recommended Land Pattern

The TS-2630 has four gull‑wing SMT terminals (two per side). Pads should be sized 2.0mm × 1.2mm, with a pitch of 14.0mm between the two terminal rows. A large center keep‑out area under the dome is required, free of vias and traces, to prevent shorting. The overall footprint is 68.0mm × 18.0mm.

Stencil & Solder Paste

Use a 0.12mm thick laser‑cut stencil with aperture openings reduced to 85% of the pad area. Type 4 SAC305 lead‑free solder paste is recommended. Avoid paste deposition under the dome area.

Reflow Profile

Follow JEDEC J‑STD‑020 for lead‑free assembly. Peak temperature 245–260°C, time above 217°C: 60–90 seconds. The polyester membrane is rated for short‑duration peak temperatures up to 260°C; ensure the component is not subjected to temperatures beyond this limit.

The TS-2630 has been validated through a series of mechanical and environmental tests to ensure consistent performance over 500,000 cycles. Key test data include:

• Contact resistance stability: After 500,000 cycles at 0.05A 12V DC, contact resistance remains below 200 mΩ.
• Vibration resistance: 10–500 Hz, 1.5mm double amplitude for 2 hours per axis, per IEC 60068‑2‑6. No contact opening longer than 100 µs.
• Thermal shock: 100 cycles between −30°C and +80°C per IEC 60068‑2‑14. Membrane adhesion and actuation force remain within specification.
• Humidity aging: 240 hours at 40°C, 90–95% RH. Insulation resistance maintained above 50 MΩ, and no delamination of the membrane layer.
