ABSTRACT:
An electric switching device for making or breaking the electric continuity between electric connecting elements under the action of an external force includes, in a single case, at least one electric switch having a control member therefor, a movable operating member specific to each switch mounted in the casing for sliding movement along the switch, a tapping in each operating member having its axis parallel to the sliding direction of the operating member, and a rod threadedly cooperating with each tapping, each threaded rod having a first end on which the external force is directly exerted and a second end which can be rotated by an appropriate tool passing through a wall of the case, and the operating member comprises a substantially cylindrical sleeve acting against a coaxially mounted resilient return member, the sleeve having a member directly cooperating with the control member of the switch.
