TE Connectivity FSM4JSMATR Tactile Switch, SMD, 160gf, 50mA 24VDC

The TE Connectivity FSM4JSMATR is a high-quality, low-profile tactile switch engineered for reliable performance in compact electronic assemblies. This single-pole, single-throw (SPST) switch features a 5mm round black button actuator, designed for a positive tactile feel with an actuating force of 160gf. It operates on an off-(on) momentary action, perfect for user interface controls.

Constructed for durability, it boasts a robust build with a brown case and a black polyamide actuator. The electrical contacts are made from silver-plated copper alloy, ensuring excellent conductivity and a long electrical lifetime of 200,000 cycles. Its surface-mount design with gull-wing terminals facilitates efficient automated PCB (printed circuit board) assembly, supporting a vertical mounting angle for space-constrained applications.

With a compact footprint of 6mm x 6mm, this non-illuminated switch is an ideal component for industrial control panels, instrumentation, and a wide range of consumer electronics where dependable manual input is required. The combination of a long lifecycle and stable electrical characteristics makes it a trustworthy choice for critical circuits.
