Keycaps with Superbly Even Illumination
Full-face, homogenous illumination using MENTOR's world-leading Light Guide expertise

The faces of the switch caps are precision-designed area light guides, providing totally homogeneous illumination with no hot-spots, despite using just two SMD LEDs.
Novel 3-part SMD switch design for flexible solutions

The conventional design approach is to specify an "all-in-one" component supplied as a complete illuminated switch assembly. MENTOR's novel solution offers the illuminated cap separately from the switch and LEDs.

This design approach offers almost limitless flexibility in terms of mixing and matching switch cap types to produce complex panels, and the use of RGB LEDs allows an infinite choice of switchable colours from a single illuminated switch.

Patented Illuminated Switch Caps
MENTOR's switch caps are an elegant, cost-effective solution for illuminated switching. The innovative design is the result of MENTOR's near 100-year legacy in the manufacture of electronic components, allied with their position as world-leaders in high-precision light guides and optics.
"Spotlight" Status Indicators
In addition to Illuminated Status Indicators (ie switch caps without a switch component), MENTOR offers switch caps with one or two Spot Indicators to indicate subtleties in the overall status indication. The overall design and dimensions of these caps is identical to the full-illumination switch caps.
Low Profile Switch Caps
These low-profile illuminated caps are similar to MENTOR’s tactile switch based illuminated switch caps, but are low profile and designed for use with dome switches in membrane keypads. Despite the low height, the light guide design of the cap ensures full homogeneous illumination using four SMD LEDs. More...
Switch Caps with Text & Graphic Inserts
This range of illuminated switch caps with incorporated text inserts is for use with painted/coated enclosures. The illuminated switch design incorporates a shoulder so that the top of the cap protrudes from the enclosure. This design securely retains the caps, even in harsh environments. More...
Established in 1920, MENTOR GmbH is an extremely successful, self-funded and highly-invested company with legendary standards of efficiency. It has 600 employees and is German headquarted with additional substantial manufacturing facilities in Germany, Poland and Tunisia.

Standard stocked parts encompass opto and light guides, handles, knobs, switches, sensors etc. Around 50% of turnover comes from MENTOR innovatively fulfilling customer-specific requirements from design to finished component, all in-house and very cost-effectively.

Opto design and manufacture is a core and world-leading MENTOR competency and they are 1st tier suppliers to many major auto companies.

This experience has resulted in MENTOR developing unique skills; they are able to virtually design optics and take these to in-house production without the need for prototyping. Many non-automotive companies are now exploiting these capabilities.
Multitron Ltd was established in January 2012 with substantial support from MENTOR. Its management has a 20-year track record of assisting Design Engineers with MENTOR solutions.

Multitron is MENTOR's sole agent in the UK & ROI and is also contracted to represent MENTOR to major global "catalogue-based" distributors and OEMs. Its three main objectives are:
  • Assist Design Engineers to successfully identify and exploit the many elegant design solutions that can be found within the broad range of MENTOR standard and semi-custom components.
  • Managing "Total Solution" projects that allow OEMs to benefit from MENTOR's unique combination of opto and electronic design expertise, coupled with legendarily efficient in-house manufacturing competence.
  • The efficient management of MENTOR's supply chain to major global catalogue-based distributors and OEMs
