The 0633B is a sealed tiny pushbutton switch from the EP Series designed for use in telecommunications, networking, and instrumentation equipment. It features epoxy sealing against solder and cleaning processes, with contact resistance below 20 mO typical at 2–4 V DC and 100 mA, and an insulation resistance of 10? O minimum. The switch operates over a temperature range of –30°C to +85°C with a dielectric strength of 1000 Vrms minimum at sea level, and offers an IP57 degree of protection. Available in multiple termination configurations including PC thru-hole, right-angle PC thru-hole, wire wrap, and surface mount options, the 0633B is ideal for applications requiring sealed, reliable switching in compact form factors.
