E112LYCQE is a sealed momentary pushbutton switch from the E010 Series, featuring a single-pole double-throw (SPDT) contact configuration with epoxy seal protection. The switch is designed with a wire wrap termination option and operates with silver contact material, delivering contact ratings of 4 amps at 125 V AC or 28 V DC. It maintains contact resistance below 20 mO typical at 2–4 V DC with 100 mA, and provides an electrical life of 40,000 make-and-break cycles at full load with insulation resistance of 10? O minimum. The operating temperature range spans -30°C to 75°C, and the switch is process sealed to withstand soldering and cleaning operations. This switch is ideal for instrumentation, telecommunications, networking equipment, and computer peripherals where reliable sealed switching and long operational life are required.
