C Choice of cap sizes in .315 (8.0mm) and .394 (10.0mm) diameter cap design for simple, snap-on installation. High torque bushing prevents rotation and separation from metal frame during installation. Stainless steel frame resists corrosion. Snap action contacts give smooth actuation, short stroke, light touch, and audible feedback. This mechanism also provides long mechanical life. Molded-in terminals prevent entry of solder flux, dust, and other contaminants100 x .100 (2.54mm x 2.54mm) terminal spacing conforms to standard PC board grid spacing. Round terminals for easier through-hole mounting on PC boards.
