1-1571636-0 is a 50 mA tactile switch featuring a round actuator with normally-open (NO) configuration, designed for low-profile surface-mount PCB applications. The switch incorporates stainless steel contact base material with silver contact plating, a thermoplastic LCP case with black color, and a violet nylon actuator with a flush profile. It delivers tactile feedback with an actuator force of 260 g (9.17 oz) and operates at 24 VDC with an operating temperature range of -35°C to +85°C. The switch includes an ESD grounding terminal, ganged configuration support, and gull-wing leg style for reliable PCB mounting. This component is ideal for control panels, industrial equipment, and consumer electronics requiring durable tactile feedback and low-profile form factors.
