It is constructed with a 5.2 mm high soft actuator, gull-wing terminations, and silver-plated contacts. This switch requires an operating force of 2.0N to provide momentary, normally open, SPST action and is rated for an operating life of 500,000 cycles. Compliant with RoHS and sealed to IP67 standards, it operates reliably in temperatures from -40°C to 85°C. Its robust design makes it suitable for use in automotive, industrial electronics, computer infrastructure, and mobile phone applications.
