Standards & Certifications Flammability Standards: UL94V-0 available The B Series toggles have not been tested for UL recognition or CSA certification. These switches are designed for use in a low-voltage, low-current, logic-level circuit. When used as intended in a logic-level circuit, the results do not produce hazardous energy.

Specifically developed for logic-level applications. Antistatic superstructure, consisting of the carbon impregnated bushing and the support bracket, prevents static discharge to the contacts. Static electricity from an operators touch travels from actuator through the bushing and bracket to the PC board. Locking lever mechanism offered as a toggle option. Optional threaded, 6mm diameter bushing for panel seal mounting meets IP65 of IEC 60529 specifications (similar to NEMA 4 and 13). Totally sealed body construction prevents contact contamination and allows time- and money-saving soldering and cleaning. Epoxy sealed terminals lock out flux and other contaminants. Award-winning STC contact mechanism with benefits unavailable in conventional mechanisms: smoother, positive detent actuation, increased contact stability and unparalleled logic-level reliability. (Additional STC details in Terms & Acronyms see Supplement section.) .100 x .100 (2.54mm x 2.54mm) terminal spacing conforms to standard PC board grid spacing.
