Switch control apparatus for electric plants

摘要

A switch control apparatus for electric plants, comprises a box-like body (2) which is adapted to be anchored to a fixed o movable part of an electric plant and has a closing panel (3) with at least one passage (4) therethrough, at least one contact unit (8) which is accommodated in the box-like body (2) at the passage (4) and is adapted to be electrically connected to at least one respective electric circuit of the plant for selective open/close control thereof, at least one actuator (9) which is adapted to interact with the contact unit (8) for the latter to ensure selective opening/closing of the respective circuits, anchor means for anchoring the contact unit (8) to the actuator (9). The anchor means (10) comprise a container member (11) which is adapted to enclose and contain said at least one contact unit (8) and to be anchored to the closing panel (3) in the box-like body (2) for stably securing the contact unit (8) on the actuator (9).
