Abstract
The present disclosure relates to an electromechanical switching device comprising switching contacts configured to close an electrical circuit, wherein the switching contacts have a first switching contact and a second switching contact, wherein the first switching contact and the second switching contact can be brought into contact in order to close the electrical circuit, wherein at least one of the switching contacts s formed from a plurality of closed bodies which are arranged against one another, and wherein hollow spaces for receiving liquid are arranged between the closed bodies.
Claims16
An electromechanical switching device, comprising:
- a plurality of switching contacts configured to close an electrical circuit, wherein the switching contacts comprise a first switching contact and a second switching contact, wherein the first switching contact and the second switching contact are configured to contact each other to close the electrical circuit,
- wherein at least one of the switching contacts is formed from a plurality of closed bodies arranged against one another, and wherein hollow spaces configured to receive liquid are arranged between the closed bodies,
- wherein the at least one switching contact is configured as a cone comprising a cone to surface configured to close the electrical circuit, wherein the cone is formed by a plurality of layers of the closed bodies arranged against one another, and
- wherein the first switching contact is formed from a first plurality of closed bodies arranged against one another and the second switching contact is formed from a second plurality of closed bodies arranged against one another, and wherein the first plurality of closed bodies comprises a first plurality of hollow spaces arranged between the first plurality of closed bodies and configured to receive the liquid, and wherein the second plurality of closed bodies comprises a second plurality of hollow spaces arranged between the second plurality of closed bodies and configured to receive the liquid.
An electromechanical switching device, comprising:
- a plurality of switching contacts configured to close an electrical circuit, wherein the switching contacts comprise a first switching contact and a second switching contact, wherein the first switching contact and the second switching contact are configured to contact each other to close the electrical circuit,
- wherein at least one of the switching contacts is formed from a plurality of closed bodies arranged against one another, and wherein hollow spaces configured to receive liquid are arranged between the closed bodies,
- wherein only one of the switching contacts is formed from the plurality of closed bodies, wherein the other switching contact is configured as a solid switching contact without any hollow spaces for receiving the liquid, wherein the solid switching contact is configured as a switching contact plate or as a switching contact bar, and
- wherein the solid switching contact comprises a first contact thickness, and wherein the switching contact formed from the plurality of closed bodies comprises a second contact thickness, wherein the second contact thickness is greater than the first contact thickness.
