Light pipe turns non-lighted pushbuttons into lighted units

6 October 2004 Opto-Electronics

BivarOpto has a new light pipe that is specifically designed to operate with board-mounted pushbutton switches, enabling non-lighted switch models to perform the same function as lighted pushbutton switches. For use in conjunction with surface mounted LED chipsets, applications include medical devices, professional recording consoles and test and measurement instruments, where smaller switch indicators are vitally needed for more compact control panels or smaller equipment.

The new PBLP Series offers an integral prism design within the light pipe, directing the surface-mounted LED light down the centre of the light pipe. It includes a slide-on base for easy mounting onto industry standard pushbutton shafts of through-hole or surface-mounted PCB-mounted switches. By positioning the switch immediately behind an SMT LED chip, the light pipe immediately enables the otherwise non-illuminated switch to become a 'lighted pushbutton switch' unit in effect.

The PBLP design uses Bivar's high-contrast materials providing improved contrast ratio for light transmission of surface or through-hole mounted LEDs. The light pipes are water clear in off-state appearance and take full colour when in the on state.
