Würth Elektronik WS-TASV tact switches
Würth Elektronik’s WS-TASV tact switch for SMT assembly is a space-saving device with a footprint of just 4.1 x 2.8 mm and height of 1.9 mm. Three variants are available, colour-coded according to their actuating force: 200 g (black), 300 g (white) and 400 g (salmon). The washable tact switches are designed for an operating temperature range of -55 to +125°C.
All metallic parts of the switches are tested for corrosion resistance with a 48 h salt spray test. Polyimide film protects the tact switch even under extreme operating conditions. High-quality snap domes made of stainless steel provide low friction — tested in full-load life cycle.
The rated current is 50 mA and rated voltage is 32 V. The service life is between 100,000 and 200,000 cycles, depending on the operation force. The initial contact resistance is 100 mΩ, and after service life testing is 2Ω.
