NKK Switches has released a complete line of ultraminiature electromechanical switches including toggles, rockers and pushbuttons for handheld instruments. These G, GB, GB2 and GW series switches incorporate NKK's Sliding Twin Crossbar (STC) contact mechanism for high logic-level switching reliability and smooth detent action.

UL94V-0 flammability rating
All of these ultraminiature electromechanical switches are rated for 0.4VA maximum at 28V AC/DC maximum and feature a standard terminal spacing of .100 x .100 inch to conform to the standard PCB grid layout. The GB2 and GW series switches may be used in telecommunications applications due to their UL94V-0 flammability rating.

The G series toggles and rockers are available in single- or double-pole models and five different circuit combinations, including momentary and maintained options with up to three actuator positions. PC terminal style mounting can be specified in straight, right-angle and vertical-mount versions for toggle actuators and straight PC or right-angle mount for rockers. Rocker caps can be ordered in red, black or white. The G series toggles and rockers are IECQ approved and totally process sealed for automated processing techniques including flux-cleaning procedures.

The GB pushbutton switches are also process sealed. The bushing and housing are constructed of one molded piece. In addition, a rubber o-ring surrounds the actuator, and a rubber seal surrounds the base where it fits into the actuator. Cap colors include red, black or white.

Lower cost
The GB2 and GW series of ultraminiature and ultrathin pushbutton and rocker devices offer a lower-cost solution. These devices feature a rating of UL94V-0 for flammability.

The single pole/single throw GB2 pushbuttons feature a momentary circuit. These switches are available in straight PC, with or without a support bracket, and a right-angle bracketed mount. The GB2 features a unique off-center actuator that enables easy actuation in high-density mounting situations, while avoiding accidental operation in compact environments, said NKK.

The GW series of rocker and paddle-actuated devices are available in both spdt and dpdt circuit configurations. These maintained circuits are two position, ON-ON. Terminal options include straight PC, right-angle bracketed and vertical-bracketed PC mounts.

Pricing starts at $1.46 each in quantities of 1,000. Availability is from stock to six weeks.
