NKK Switches Announces the B Series of Antistatic Toggles

Subminiature Devices are Designed for Logic-Level Applications

Scottsdale, Ariz. (March 1, 2006) - NKK Switches, world class manufacturer of more than four million electromechanical switches, today announced the new B series specifically designed for logic-level applications.

The B series of process sealed, subminiature, antistatic, PC mount toggle switches incorporate NKK's award winning sliding twin crossbar contact mechanism. This contact design provides unparalleled switching reliability and smoother positive detent action.

The B series features an antistatic superstructure, consisting of a carbon-impregnated bushing. When configured with a support bracket, it prevents static discharge to the contacts. Static electricity from the operator's touch travels from the actuator, through the bushing and bracket, to the PC board.

B series toggles are available in both single and double-pole models with a comprehensive offering of eleven circuits in both momentary and maintained. Actuators can be specified in a myriad of styles, lengths and colors. Options include standard bats, locking lever, anti-static levers, flatted levers, colored sleeves and snap on paddles. In addition, an optional threaded, 6mm diameter bushing for panel seal mounting is available and meets IP65 of IEC60529 specifications.

The body of the B series, including the bushing, is a mere .515" in height. The single-pole version is .268" wide and the double-pole is .346". These measurements include a bushing .106" long. The terminals are .100" X .100" spacing and conform to standard PC board grids. Engineers can specify from several different mounting options, which include straight PC in bracketed and unbracketed models, vertical PC and right angle PC mounts.

NKK's B series are process sealed and feature a totally sealed body construction that prevents contact contamination, which allows for time and money-saving soldering and cleaning. Ultrasonically welded terminals lock out flux and other contaminants. The case housing is constructed of glass-reinforced polyamide.

B series toggles are 0.4VA maximum @ 28V AC/DC maximum. The mechanical life is 100,000 operations minimum for maintained circuits and 50,000 operations minimum for momentary circuits. The electrical life is rated at 50,000 operations minimum. The contact timing is nonshorting and the angle of throw is 26°.
