C&K Components, a leading global manufacturer of electromechanical switches, smart card interconnect devices, and high reliability connectors, has announced that they have added painted and laser-etched symbols to the backlit caps on the APB Series industrial pushbutton switches. Available LED’s in either blue or white, the backlit caps provide a highly visible indication that the switch has been activated or turned on. Additionally, since the LEDs are independent of the switching mechanism, customers can control the LED to indicate whether the switch is in the up (on) or down (off) position, and can even control the level of brightness.
