New Tact & Rotary Switches

Würth Elektronik's switches range is supplemented with four new series.

In the tact switch range the series of the type 6x6 mm ( WS-TST) and 12x12 mm ( WS-TSW) are available in THT. Cover and contacts are made from stainless steel, and the contacts have an additional silver plating. With silver-plated contacts as well as the actuator and housing made of LCP UL 94V-0, the switches are not only lead-free and RoHS compliant but are also suitable for operating temperatures between –40 and +85°C. Switches of this size are characterized by a contact rating capacity of up to 50 mA, 12 VDC, an dielectric withstanding voltage of >100@500 VDC MΩ, a dielectric strength of 250 VAC/mn, as well as a contact resistance of 100 mΩ.

In the rotary switch range Würth Elektronik provides one SMD and one THT family in 7x7 mm type. The switches in the WS-RAS and WS-RAT series have a stainless steel cover. The contacts are gold-plated. Actuator and housing are made from LCP UL 94V-0. The components are RoHS compliant and are suitable for operating temperatures between –60 und +125°C. The switches are characterized by a contact rating capacity of up to 100 mA, 42 VDC, an dielectric withstanding voltage of >100@250 VDC MΩ, a dielectric strength of 250 VAC/mn, as well as a contact resistance of 80 mΩ. Both switch families are available with 10 or 16 positions and with real or complement code.

All tact switches are suitable for reflow soldering according to JEDEC J-STD-0200.
