FSM6JSMATR is a surface-mount tactile switch from the FSMJSMA series designed for compact electronic applications requiring reliable momentary switching. The switch features a 6×6 mm footprint with a 0.236 inch (6.0 mm) square body and operates at 50 mA @ 12 VDC with an initial contact resistance of 100 milliohms maximum. It incorporates copper alloy silver-plated contacts, a PPS case and actuator button, and steel tin-plated cover for durability. The device delivers an actuation force of 260 ± 50 grams with 0.010 inch (0.254 mm) actuator travel, supporting up to 100,000 cycles with 500 VAC dielectric strength and 100 megohms minimum insulation resistance @ 100 VDC. Operating across -20°C to +85°C, this switch is ideal for consumer electronics, industrial controls, and portable devices requiring space-efficient, high-reliability switching solutions.
