KT11P4SM34LFS is a full SMT top and side actuated sealed tact switch from the KT Series. It features an SPST normally open contact arrangement with SMT termination and a hard plastic P4 actuator with 3.96 mm height. The switch offers a contact rating of 1.0 VA max at 32 V AC or DC, contact resistance below 50 mO typical, and an electrical and mechanical life of 100,000 make-and-break cycles at full load. With dielectric strength of 250 Vrms minimum and insulation resistance of 10? O minimum, it provides reliable performance across operating temperatures from -40°C to 90°C (Ag version) or -40°C to 125°C (Au version). This tactile switch is ideal for telecommunications, computer products, instrumentation, and power supply applications where reliable switching and RoHS compliance are required.
