FSM16JH is a tactile pushbutton switch designed for through-hole printed circuit board applications with a vertical mount orientation. It features a single pole-single throw (SPST) configuration with a 50mA contact rating and an extended round black nylon actuator with a length of 13.40 mm (0.527 inches). The switch utilizes silver-plated contacts and a nylon case material, providing reliable tactile feedback for user interface applications. This switch is ideal for consumer electronics, industrial control panels, and embedded systems requiring durable, cost-effective push-button actuation with consistent tactile response.
