Pushbuttons endure more than 3 million mechanical ops

Aimed at critical and demanding applications, NKK Switches' has developed the FP01 Series of contactless illuminated pushbutton switches that use a diode photo interrupterrather than traditional contacts to ensure high reliability and a long life of 3 million mechanical operations minimum.
These pushbuttons are an alternative for engineers charged with designing panels for equipment exposed to corrosive gases and similarly harsh environments, where reliability due to contact contamination is a concern. The rugged construction and smooth actuation of the FP01 Series allows repeated and rapid actuation force anywhere on the cap surface. Typical high usage applications for these devices include operator controlled industrial machinery, vending machines, gaming and museum displays.
These switches feature bright LED illumination with the LEDs as an integral component of the switch. Engineers can configure FP01 devices for highly visible status indication by choosing colored actuators to match the red, green or amber LED illumination, or for subdued illumination in low-light environments by specifying a white actuator over the colored LED.
Featuring a single photo transistor that activates a momentary ON position, these pushbuttons are snap-in mount for easy installation. Each device includes a six pin socket and engineers can choose between assembled connector plugs with wire leads or unassembled plugs and pins.
