B Series toggle switches

From NKK Switches comes the latest B Series of process-sealed, PCB mount, antistatic, subminiature toggle switches for logic level applications.

B Series toggle switches incorporate NKK's Sliding Twin Crossbar contact mechanism for reliable switching and positive detent action. The company also attributes contact reliability to the switch's structure, which consists of a carbon-impregnated bushing. When configured with a support bracket, static discharge to the contacts is prevented. Static electricity from the operator's touch travels from the actuator through the bushing and bracket directly to the PC board.

With a case housing constructed of glass-reinforced polyamide, these toggle switches also feature process-sealed body construction that prevents contact contamination. Terminals are ultrasonically welded to lock out flux and other contaminants.

An optional threaded 6mm diameter bushing for panel seal mounting is also available and meets IP65 of IEC60529 specification. Engineers can specify from several different mounting options, including straight PC in bracketed and unbracketed models, vertical and right angle mounts.

The B Series is available in both single and double pole models with a comprehensive offering of 11 circuits in momentary and maintained actions.
