Abstract (en)
A switching device (100) for opening and closing a circuit is provided. The switching device comprises a vacuum interrupter unit (124) with a first stem (126) and a second stem (128). The switching device further comprises a rigid contact member (140) having a slot (142) and a contact arm (144). The switching device further comprises a compressible contact member (150) positioned inside the slot of the rigid contact member. In the switching device, the second stem is configured to move linearly; such that in a first position, the second stem is in electrical engagement with the compressible contact member thereby closing the circuit, and in the second position, the second stem is out of electrical engagement with the compressible contact member thereby opening the circuit.
