The TCS43 is a microminiature SMT tactile switch designed for high-performance applications where compact dimensions, high reliability, and precise haptic feedback are required. With a footprint of just 4.2 × 3.2 mm and a low build height of 2.5 mm, it enables space-efficient PCB layouts without compromising ease of use.
The switch offers three actuation forces (180 gf, 250 gf, 400 gf; corresponding to 1.76 N to 3.92 N), allowing engineers to precisely tailor the user experience to the application. With a mechanical lifespan of up to 100,000 cycles, the TCS43 delivers long-term reliability, even in demanding environments.
The electrical performance supports low-power designs (10 µA to 50 mA, 1 to 12 VDC), while the contact resistance remains ≤100 mΩ for stable signal integrity. The device operates reliably within a wide temperature range (-40 °C to +90 °C), making it suitable for both consumer and medical applications.
Applications
Typical applications are user interfaces such as on/off switches, menu navigation, and parameter selection in high-end consumer electronics, home automation systems, IoT devices, and medical equipment (e.g., blood pressure monitors, ventilators).
The TCS43 combines a compact design, robust performance, and flexible actuation options, making it an ideal choice for next-generation interface solutions.
