Magic switch

A novel switching technology developed by Herga Electric makes it possible to operate a switch on the other side of walls without the need to drill holes.

A novel switching technology developed by Herga Electric makes it possible to operate a switch on the other side of walls (500 – 100mm thick) without the need to drill holes.

The switch, which can be either rotary or push button, is mounted on one side of a panel, either horizontally or vertically with the control electronics on the other side. The mechanism allows the switch to work through plastics, marble, wood, glass, sheet stainless steel and granite.

The ‘Freemount’ Top switch makes use of GMR – giant magneto resistive – technology and is self-calibrating to accommodate the various thicknesses of the substrate.

Because the actuator is entirely passive, the system could be suitable for use in hazardous environments or where EMC issues are concerned. It also avoids problems with sealing as no holes are required in the panel.

As well as industrial applications, the technology is expected to find use in the leisure, marine, kitchen, bathroom and access control environments.
