PCB mountable illuminated subminiature pushbutton switch of 0.4VA rating

NKK Switches has released the new NP01 Series of smooth actuation subminiature pushbutton switches. Available in both illuminated and non-illuminated versions, the series is designed for reliable applications and is aesthetically pleasing in look.

Utilizing a single LED, the NP01 switches offer full illumination that can be specified in red, green or amber, or a bicolor LED with a red/green combination. Non-illuminated versions feature caps available in black, white, red and gray. Caps are 12mm square and can be specified with clear lenses and matching colored diffusers, or with white diffusers to match any color.

The smooth touch actuation of the NP01 Series is achieved through the use of a patent pending, uniquely designed mechanical silicon rubber structure. This smooth actuation makes the NP01 switches ideal for a vast spectrum of applications ranging from audio visual, industrial automation and test and measurement equipment.

The NP01 Series also gives engineers the choice of high (2.5N) or standard (1.5N) operating force. The distinctive long stroke of 1.5mm allows operators to feel secure in the actuation of the circuit. The compact dimensions of these switches measure just 12.5mm from PCB to the top of the cap. They are available in SPST momentary circuit and carry a rating of 0.4VA @ 28V AC/DC.

Unique in the industry, is the alternating legend option offered with the NP01. The bicolor red/green device can be specified with standard off the shelf legends of ON-OFF, START-STOP or OPEN-CLOSE. This provides an alternative to traditional methods of adding common legends, such as laser etching or pad printing and increases the practical functionality of the switches.

Gold plated contacts provide extremely reliable logic-level switching. The design allows for a conservative rating of 500,000 operations minimum of mechanical and electrical life and the terminals are crimped to ensure secure PC mounting and to prevent dislodging during soldering. In addition, they are molded-in to prevent the entry of flux, solvents and other contaminants.
