SCOTTSDALE, AZ – NKK Switches announce the availability of the B Series of process sealed, PCB mount, antistatic, subminiature toggle switches. These new toggle switches were specifically designed for logic level applications.
B Series toggle switches incorporate NKK’s award-winning Sliding Twin Crossbar contact mechanism to ensure unparalleled switching reliability and smooth positive detent action.
Contact reliability is increased even further as a result of the series’ antistatic superstructure, which consists of a carbon-impregnated bushing. When configured with a support bracket, this prevents static discharge to the contacts. 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 specifications. 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 eleven circuits in momentary and maintained actions.
The B Series is the smallest switch in the marketplace to offer a locking lever actuator. Actuators can be specified in a variety of styles, lengths and colors. Other actuator options include standard bat, antistatic lever, flatted lever, colored sleeves and snap-on paddles.
The body of the B series, including bushing, is a compact 0.515” in height. Including a .106” long bushing, the single pole version is .268” wide and the double pole .346” wide. Terminal spacing is .100” x .100” and conforms to standard PC board grids for easier board layout.
These toggle switches are rated 0.4VA maximum @ 28V AC/DC maximum. The mechanical life is rated at 100,000 operations minimum for maintained circuits and 50,000 operations minimum for momentary circuits. Electrical life is rated at 50,000 operations minimum.
