FSM1LP is a low profile surface mount tactile switch from the Alcoswitch series, designed for compact PCB applications. It features a 6mm x 6mm (.236" x .236") footprint with silver clad plated copper alloy contacts and PPS case and stem materials. The switch offers a contact rating of 50mA at 12 VDC, initial contact resistance of 100 milliohms maximum, and insulation resistance of 100 megohms minimum at 100 VDC. Operating temperature ranges from -20°C to +85°C with a life expectancy of up to 100,000 cycles. This tactile switch is ideal for consumer electronics, industrial controls, and other applications requiring reliable momentary switching in space-constrained designs.
