Custom light guide systems
For use under a membrane underlay

This range of MENTOR Plunger Switch Caps and Status Indicators is for use under a membrane overlay only. Other ranges suitable for use with painted/coated enclosures are available.

For applications where full illumination is not required

These Switch Plungers are designed for keypad applications where full illumination is not required. They can be combined with other pushbutton caps and signal indicators from MENTOR’s range of keypad components.

Two options

Two switch plunger variants are available: an illuminated switch plunger offering up to four illuminated points; or a switch plunger without illumination.

Separate LEDs and switches

As with all of MENTOR’s the switch cap products, they feature an innovative 3-part component solution, with the LEDs and switches supplied separately to the switch caps.
MENTOR’s illuminated switch plungers are designed for applications with CHIP LEDs and a large number of states can be indicated using dual or RGB LEDs. The plungers are available in two sizes: 15 x 15mm and 19 x 19mm; and two heights: 12.5mm and 9.7mm. All plungers have integral anti-twist protection to ensure reliable component insertion in automated assembly processes.

MENTOR offers its own pushbutton switches, but both the switches and LEDs can be sourced from other manufacturers, offering flexibility of supply.

Custom solutions

Customer-specific cap heights can be realised with little or no tool cost. Other possibilities include body-coloured switch caps and signal indicators to suggest potential colour, even when their illumination is off. Different printing processes provide many graphics / text options.
