The 8532J81ZQE32 is a subminiature SPST (Single Pole Single Throw) momentary pushbutton switch from the 8500 Series, designed for applications requiring reliable contact switching at 1 Amp @ 120 V AC or 28 V DC. This model features a snap-in front mount actuator (J81) with frame, offering a compact form factor with a total travel of 0.050 inches (1.27 mm) and an actuation force of 6 oz (170 g). The switch incorporates silver contact material (Q) with a contact resistance below 30 mO typical, an insulation resistance of 10? O minimum, and dielectric strength of 1,000 Vrms minimum, ensuring reliable electrical performance. It operates over a temperature range of -30°C to 65°C and is RoHS compliant with an epoxy terminal seal compatible with bottom-wash PCB cleaning methods. The 8532J81ZQE32 is ideal for detection, telecommunications, networking equipment, and computer peripherals where space constraints and reliable momentary switching are critical requirements.
