Schurter TCS43 Microminiature Tactile Switches

Schurter TCS43 Microminiature Tactile Switches offer compact size, reliability, and precise haptic feedback for high-performance applications. These switches provide three actuation force options, which include 180gf, 250gf, and 400gf, equivalent to 1.76N to 3.92N. The TCS43 microminiature tactile switches allow engineers to fine-tune the user experience depending on application requirements. These switches support a mechanical lifetime of up to 100000 cycles, ensuring long-term reliability even in demanding environments. The TCS43 microminiature tactile switches provide a footprint of just 4.2mm x 3.2mm and a low profile of 2.5mm height, enabling space-efficient PCB layouts without compromising usability. These Switches deliver electrical performance that supports low-power designs with 10µA to 50mA and 1VDC to 12VDC, while contact resistance remains ≤100mΩ for stable signal integrity.

The TCS43 microminiature tactile switches are REACH and RoHS-compliant. These switches operate reliably over a wide temperature range of -40°C to 90°C, suitable for both consumer and medical applications. Typical applications include user interfaces such as on/off switching, menu navigation, and parameter selection in high-end consumer electronics, home automation systems, IoT devices, and medical equipment.
