Bushing and snap-in mount versions available snap-in models offer C many style and color choices to enhance front panel appearance. Light touch actuation. High torque bushing prevents rotation and separation from metal frame during installation. Stainless steel frame resists corrosion. Case of heat resistant resin meets UL 94V-0 flammability rating. Higher insulating barriers protect against crossover in double pole devices. 1,500V dielectric strength between contacts and case is accomplished by clinching the frame away from the terminals. Epoxy sealed terminals prevent entry of solder flux and other contaminants.
