Toggle and Pushbutton Switches are process-sealed.

Press Release Summary:

Series G3T toggles and G3B pushbuttons feature Sliding Twin Crossbar contact mechanism for logic level switching reliability. Contacts are gold-plated and wiped clean with every actuation. Both series have bushing and housing constructed of one molded piece with rubber o-ring. Available as single- or double-pole, G3T toggles can be configured in 5 circuits, including momentary and maintained action, while G3B pushbuttons are offered in momentary circuits.

NKK Switches Offers Series of Ultra-Miniature, Sealed Devices

Featuring Sliding Twin Crossbar: logic level switching reliability

Scottsdale, Ariz. (Dec.13, 2004)-Committed to providing the highest quality and the most reliable switches in the market, NKK Switches announced the G3T and G3B series of ultra-miniature, sealed, surface mount toggle and pushbutton devices.

The G3T and G3B series devices feature NKK's award winning STC (Sliding Twin Crossbar) contact mechanism. This innovative design guarantees unparalleled logic level switching reliability. The contacts are gold plated and wiped clean with every actuation, providing a smoother, positive detent actuation and increased contact stability.

Both the G3T toggles and the G3B pushbuttons are completely process sealed for automated processing techniques including flux-cleaning procedures. The bushing and housing are constructed of one molded piece, and a rubber o-ring surrounds the actuator. In addition, a rubber seal surrounds the base where it fits into the actuator. The terminals are epoxy sealed and molded into lock out flux, solvents and other contaminants. The heat resistant resin used to construct the housing, base and actuator on all these SMT switches allows vapor phase and infrared convection reflow soldering.

These devices are available in single pole or double pole. The G3T toggles can be configured in five different circuits including momentary and maintained action. The G3B pushbuttons are available in momentary circuits. Design engineers can specify upright, upright with support bracket or right angle mounts. The electrical rating for all options is 0.4VA maximum @ 28V AC/DV maximum. They are designed for use in low voltage, low current logic level applications. The ultra-miniature size of the G3T and G3B allows high-density mounting. Their extremely light weight of .25g makes these switches ideal for handheld equipment as well as innumerable other applications.

Coplanarity control is excellent and guaranteed, making the use of solder paste on decreasing screen thickness a non-issue during processing. The tolerance zone is 0.15mm (.0059") maximum, which is the allowable distance between all considered surfaces in two parallel planes. Gull-wing terminals provide mechanical stability during soldering and simplify solder joint inspection. Tape-reel and stick-tube packaging allow rapid automated placement of these surface mount devices. Partitioned tray packaging is available upon request.
