Surface mount tactile switch featuring a SPST (Single Pole Single Throw) configuration with an Off-(On) momentary function. This non-illuminated switch offers a 1.57N operating force, 0.2mm travel, and a 50mA contact current rating at 12VDC. Constructed with a polyphthalamide actuator and silver-plated stainless steel contacts, it boasts a mechanical life of 100,000 cycles and operates within a -35°C to 85°C temperature range. The gull wing termination facilitates secure surface mounting, and the component is supplied in tape and reel packaging.
