Scottsdale, Ariz. — NKK Switches offers a complete family of tactile switches that provide design engineers with a variety of sizes and feature options. These include the HP series, CB series, JB series and JF series switches.

The HP series of environmentally-friendly, through-hole and surface-mount tactile devices features a 6-mm square body, which allows for compact mounting for a keyboard matrix. The terminals and contacts are available in gold or silver depending on design requirements. The HP switches are rated at 500,000 operations minimum for both electrical and mechanical life. The gold contacts offer the advantage of little or no oxidation or sulfurization, and a stable contact resistance. Through-hole models are packaged 100 pieces per stick tube and surface-mount versions are packed on tape and reel with 1,000 pieces each.

The CB series is another 6-mm tactile switch available in through-hole and surface-mount models. The CB tactile switches are process sealed and feature a sealed body construction to prevent contact contamination during automated soldering and cleaning. The CB series is rated for an electrical and mechanical life minimum of 100,000 operations. Packaging for through-hole models is 50 pieces per stick tube or partitioned trays, while surface-mount models are packaged 1000 pieces per tape and reel.

Both the HP and CB through-hole models feature crimped terminals to ensure secure mounting and to prevent dislodging during automated soldering. The surface-mount versions have gull-wing terminals for mechanical stability and excellent coplanarity tolerances. Actuators are flat, low profile. All actuators and bases meet UL flammability rating for 94V-0.

The JB series features a 10-mm square body. The process-sealed switches deliver aesthetically pleasing interfaces with availability in a variety of actuator heights, an array of cap styles and colors, and with red, green or yellow LED full-face illumination. Electrical and mechanical life is rated 5,000,000 operations minimum. The case and base are UL94V-0 rated.

The ultra-thin JF series is specifically designed to enhance the appearance of front panels. These switches feature an extremely low profile of 5-mm from the printed-circuit-board (PCB) to the top of the switch and offer a wide choice of body shapes and colors. The JF series is available in round or square shapes with four different actuator styles and in many vibrant colors. The JF is also available with full-face or spot illumination with red, green or yellow LEDs. Electrical and mechanical life is rated 500,000 operations minimum.

All of NKK's tactile switches are constructed with dome contacts that deliver tactile feedback to positively indicate circuit transfer. They are available in a single pole, single throw (SPST) configuration with a momentary circuit and logic level ratings. Click the link for more information about the tactile switches.

Pricing starts at $0.30 each at 1,000 pieces. Availability is from stock to eight weeks.
