Meeting standards

The new T85 version of the D4 series snap-action switches with black plastic material is said to give improved environmental performance, and are future-proof to growing customer requirements and compliance.

 

Cherry says the D4 series features an increased tracking resistance of PTI 300, a high functional reliability and excellent switching precision. Using application-specific contact materials for switching currents from 0.1A up to 21A at 250VAC, the switches are designed to offer superior contact reliability. The switches conform with IEC 60335-1 requirements: GWFI at 850°C, GWIT at 775°C and GWT 750°C. They have been designed to operate over an ambient temperature range from -40 up to +150°C.
