TP11SHCQE is a subminiature SPST off-momentary pushbutton switch designed for compact applications requiring reliable switching performance. The switch features a 0.155" high plunger with threaded 0.220" high bushing and is configured for PC through-hole termination with epoxy terminal seal compatible with bottom-wash PCB cleaning methods. The contact material is silver-plated copper alloy with silver-plated terminals, rated for 1 AMP at 120 V AC or 28 V DC, and offers contact resistance below 20 mO typical at 2-4 V DC with 100 mA. The switch provides 60,000 make-and-break cycles at full load, operates across -30°C to 85°C, and features dielectric strength of 1000 Vrms minimum at sea level. Typical applications include telecommunications and networking equipment, computers and peripherals, and instrumentation and controls where space constraints and reliable switching are essential.
