NKK Switches announce the availability of the G3T Series and G3B Series of ultra-miniature, process sealed, surface mount toggle and pushbutton switches. These devices’ small size and light weight make them ideal for handheld equipment as well as high-density mounting.Both the G3T and G3B series 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 series are also 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 in to lock out flux, solvents and other contaminants.These devices are available in single pole or double pole. The G3T toggle switches can be configured in five different circuits including momentary and maintained action, while the G3B pushbutton devices are available in momentary circuits. Design engineers can also specify upright, upright with support bracket or right angle mounts. The series’ ultra-miniature size allows for high density mounting.The heat resistant resin used to construct the housing, base and actuator on the toggle and pushbutton SMT switches allows vapor phase and infrared convection reflow soldering. Gull-wing terminals provide mechanical stability during soldering and simplify solder joint inspection.The electrical rating for all circuit options is 0.4VA maximum @ 28V AC/DV maximum. They are designed for use in low voltage, low current, logic level applications.
