TP12MS9CBE is a subminiature SPDT (Single Pole Double Throw) momentary-action pushbutton switch from the C&K TP Series, designed for applications requiring compact switching capability. The switch features a 0.200" high plunger with a 0.020" high round bushing, and is rated for 1 AMP at 120 V AC or 28 V DC with silver contact material. It offers contact resistance below 20 mO typical at 2-4 V DC with 100 mA, an insulation resistance of 10? O minimum, and dielectric strength of 1000 Vrms minimum at sea level. The device operates reliably over a temperature range of -30°C to +85°C and provides 30,000 electrical life cycles at full load. With its epoxy terminal seal compatible with bottom-wash PCB cleaning methods and RoHS compliance, this switch is well-suited for telecommunications, networking equipment, computers, peripherals, and instrumentation applications.
