Abstract
A contact unit for an electromechanical switching device includes a carrier element and a contact element connected to the carrier element. The contact element has a silver-containing layer that provides a contact area for making releasable contact with a further contact area of the switching device depending on a switching state of the switching device. The silver-containing layer includes diamond particles at least in the region of the contact area.
Claims18
A contact unit for an electromechanical switching device, the contact unit comprising:
- a carrier element;
- and
- a contact element connected to the carrier element,
- wherein the contact element has a silver-containing layer that provides a contact area for making releasable contact with a further contact area of the switching device depending on a switching state of the switching device, and
- wherein the silver-containing layer comprises diamond particles at least in a region of the contact area and a proportion of diamond particles in the silver-containing layer is at least 2% by weight at least in the region of the contact area.
2 more elements
An electromechanical switching device, comprising:
- at least two connections arranged such that they are electrically insulated from one another,
- at least one contact unit connected to one of the connections,
- a further contact area connected to another of the connections, and
- a drive unit mechanically connected to the contact unit,
- wherein the at least one contact unit comprises:
- a carrier element, and
- a contact element connected to the carrier element,
- wherein the contact element has a silver-containing layer that provides a contact area for making releasable contact with the further contact area depending on a switching state of the electromechanical switching device, and
- wherein the silver-containing layer comprises diamond particles at least in a region of the contact area and a proportion of diamond particles in the silver-containing layer is at least 2% by weight at least in the region of the contact area.
