FSM14JRT is a tactile pushbutton switch with through-hole terminals designed for momentary contact applications. This switch features a 0.512 inch (13.0 mm) actuator length and an actuation force of 160 ±50 grams, with an actuator travel of 0.10 inches (0.254 mm). The switch is rated for 50 mA at 12 VDC with an initial contact resistance of 100 milliohms maximum and an insulation resistance of 100 megohms minimum at 100 VDC. It offers a dielectric strength of 500 VAC for 1 minute and is rated for up to 100,000 cycles of operation. The FSM14JRT is constructed with copper alloy silver-plated contacts and an acetal actuator button, making it suitable for consumer electronics, industrial control panels, and general-purpose switching applications requiring reliable tactile feedback.
