The 3P0210100 is a miniature pushwheel switch from the C&K 3P Series designed for applications requiring reliable position selection and encoding. It features a snap-in front mount design with a section pitch of 0.300 inches (7.62 mm) and supports BCD 1-2-4-8 encoding with 10 position capability. The switch is constructed with polycarbonate housing and pushwheel (UL 94V-0 rated), gold-plated rotor contacts over nickel and copper alloy, and hard gold-plated stator contacts on epoxy fiberglass. Electrical specifications include a maximum switch rating of 0.4 VA at 100 mA and 28 V DC, contact resistance below 300 mO typical at 2-4 V DC with 100 mA current, and an electrical life of 100,000 actuations. The device operates over a temperature range of -10°C to 65°C with dielectric strength of 500 Vrms minimum between common terminal and any output. Available with multiple termination options including short PCB, extended PCB, and solder pin configurations, this switch is ideal for test and measurement equipment, industrial machinery, and computer peripherals requiring compact, reliable position encoding.
