A circuit breaker and/or earthing switch are disclosed wherein a rotatable spindle nut, which is mounted in a spindle housing, displaces a spindle in a translatory manner, thus displacing contact elements of the switching device. The spindle actuates a contact pin that is configured in a contact carrier by a connection yoke that is common to all phases or poles and an isolating bar for each phase or pole.

Spindle drive for a switch disconnector and/or grounding switch

A disconnecting/grounding switch for metal-encapsulated, gas-insulated high-voltage switchgear. A first fixed contact is connected to a first inner conductor. A second contact is connected to an inner conductor running at right angles to the first inner conductor. A moving contact member connects the two fixed contacts in one position and connects the second fixed contact with a fixed grounding contact in a second position. The moving contact member is a thrust contact whose path of motion runs at an angle to the first and second inner conductors and which can move linearly in a contact housing that forms the second contact. The two fixed contacts and the grounding contact are in a line. In a first position, the moving contact member can connect the first fixed contact to the contact housing; in a second position, it is located inside the contact housing, and in a third position, it connects the contact housing to the grounding contact.
