FSMH is a high-temperature tactile switch from the FSM series, designed for through-hole (THT) mounting applications. The switch features an SPST contact configuration with various actuation force options ranging from 1.0±0.5 N (60±30 gf) to 5.2±1.0 N (520±100 gf), and multiple actuator length options from 4.33 mm to 17.0 mm. The FSMH series is designed for high solder heat resistance applications, making it suitable for demanding manufacturing processes. These tactile switches are commonly used in consumer electronics, industrial controls, and other applications requiring reliable momentary switching with tactile feedback.
