KM1101RR05B is a subminiature pushbutton switch from the KM Series, featuring an SPST normally open (Off-Momentary) configuration. This switch utilizes a 1/4-40 threaded bushing mounting style with 0.225" height, 0.110" quick connect terminations, and gold-plated contacts for reliable low-level/dry circuit applications rated at 0.4 VA max at 20 V AC or DC max. The switch features 0.095" pretravel and 0.120" total travel with a 0.122" diameter actuator, and operates over a temperature range of -30°C to 85°C. With an electrical life of 10,000 actuations minimum at full load and contact resistance below 30 mO typical, this RoHS compliant switch is ideal for alarm systems, computers, and detector switch applications.
