FSM2JART is a tactile switch from the FSMJ Series designed for through-hole PCB mounting in a compact 6 x 6 mm form factor. This switch features a 260 ±75 gram actuation force with a 0.10 inch (0.254 mm) actuator travel, providing reliable momentary switching action. The switch is constructed with copper alloy silver-plated contacts, polyamide case, and polyacetal resin actuator button, delivering robust performance across an operating temperature range of -40°C to +105°C. With a contact rating of 50 mA at 12 VDC, initial contact resistance of 100 milliohms maximum, and a life expectancy of up to 100,000 cycles, the FSM2JART is well-suited for consumer electronics, industrial control panels, and portable devices requiring durable tactile feedback and long-term reliability.
