See Cleaning specifications in Supplement section. UL94V-0 rated housing & base The D2 Series toggles have not been tested for UL recognition or CSA certification. These switches are designed for use in a low-current, logic level circuit. When used as intended in a logic level circuit, the results do not produce hazardous energy. PCB Mount Miniature Toggles

Distinctive Characteristics PCB Mount Miniature Toggles Base of heat resistant resin meets UL94V-0 flammability rating. Maximized voltage capability of 48V allows use in medium source applications and increases operating life. Award-winning STC contact mechanism with benefits unavailable in conventional mechanisms: smoother positive detent actuation, increased contact stability, and unparalleled reliability. (Additional STC details under Terms and Acronyms in the Supplement section.) Round .031” (0.8mm) diameter PC terminals for easy PCB assembly. Terminal spacing conforms to standard .100”...
