Illuminated switch caps & status indicators for use under a membrane overlay
This range of MENTOR Illuminated Switch Caps and Signal Indicators is for use under a membrane overlay only. Other ranges suitable for use within enclosures are available.
Totally homogeneous illumination
This extensive range of Illuminated Switch Caps utilises MENTOR’s light guide expertise to deliver totally homogeneous illumination. The caps are unique in that their faces are proper light guides, offering full-face illumination with no hot-spots. A number of dimensional variations are available as standard stocked parts.
Switch Caps feature an innovative multi-component approach
MENTOR's ground-breaking approach offers the illuminated caps separately from the pushbutton switches and single colour or RGB SMD LEDs. This principle is illustrated by the image to the left. The SMD tactile switch and two LEDs are soldered onto the PCB and the full-illumination cap is pushed onto the square switch head. RGB LEDs can be specified to provide an infinite colour choice. Optional additional point illumination is available to indicate subtleties of switching states.
MENTOR offers its own pushbutton switches, but both the switches and LEDs can be sourced from other manufacturers, offering flexibility of supply.
Signal Indicators – where a switching function is not required
Designed for applications where a switching function is not required, MENTOR’s Illuminated Signal Indicators are similar in look and dimensions to MENTOR’s Illuminated Switch Caps, described above, so mixing both types on the same keypad is an option. Again, totally homogenous, full-face illumination is provided from just two single colour or RGB SMD LEDs to provide an infinite colour choice and optional additional point illumination is available to indicate subtleties of switching states.
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.
