Switching device for an electric appliance has a contactor with switch contacts for opening/closing a current supply circuit to the appliance and a manual activating mechanism for the contactor

摘要

An appliance's current supply circuit (CSC) has a change-over switch (COS) (7) for reversing the poles in the CSC. The COS has a second activating mechanism (10), which, when operated manually, switches over the COS contacts between first and second connection conditions. - A contact breaker (8) with a third activating mechanism (11) uses a manual operation to trigger the opening of a switch contact in a current supply circuit, whose poles are to be reversed.
