Extensions to the Würth Elektronik switch program

Push-Button Switches and a Main Switch

Waldenburg (Germany), August 13, 2025 – Würth Elektronik expands its switch program. The popular SMT-mountable short-travel push-button switches are now joined by a new size version: the “WS-TASV SMT Tact Switch 4.5*3.2 mm”. The switches are available in three versions with different actuation forces. The range of power switches is expanded with a rocker switch for a particularly space-saving device panel cut-out.

The short-travel push-buttons from Würth Elektronik are suitable both for switching functions on and off as well as for use as signal transmitters. Designed for operating temperatures from -40 to +85 °C, the tactile switches are available with actuation forces of 170, 330, and 520 gf. These short-travel switches, commonly used in remote controls, occupy an area of 4.5 × 3.2 mm and are 2.5 mm high. A new automated production process ensures strict tolerances are maintained. The service life test under full load (50 mA / 16 V_DC) showed an electrical service life of 100,000 cycles. The push-button switches have also passed a 48-hour salt spray test and a five-cycle reflow soldering test. The plastic material is UL94-approved for flammability.

Rugged main switch

The new WS-RSTV (Rocker Switch THT Vertical), designed for a device panel cut-out of just 19.2 × 6.8 mm, features a 4.75 mm (0.187") quick-connect terminal. The hot-stamped color marking integrated into the plastic is available with a horizontal or vertical “1”. This switch, with an electrical service life of 10,000 cycles, has also been tested under full load. The operating temperature ranges from 0 to +85 °C. The plastic material PA66 complies with UL94 flammability test standards and has undergone a glow wire test at 850 °C in accordance with IEC 60695-2-11 under the 61058-1 standard, as well as a UV test in accordance with IEC 60068-2-5. Available certifications include UL/ENEC 61058-1 and CQC16002160972. The contact material is a silver-plated copper alloy.
