Switch control apparatus for electric plant

摘要

A switch control apparatus for electric plants includes a box-like body which is adapted to be anchored to a fixed o movable part of an electric plant and has a closing panel with at least one passage therethrough, at least one contact unit which is accommodated in the box-like body at the passage 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 which is adapted to interact with the contact unit for the latter to ensure selective opening/closing of the respective circuits, an anchor system for anchoring the contact unit to the actuator. The anchor system includes a container member which is adapted to enclose and contain the contact unit and to be anchored to the closing panel in the box-like body for stably securing the contact unit on the actuator.

主权项

1. A switch control apparatus for electric plants, comprising:
a box-shaped body (2) adapted to be anchored to a fixed or movable part of an electric plant and having a closing panel (3) provided with at least one passage (4); at least one contact unit (8) housed into said box-shaped body (2) at said passage (4) and adapted to be electrically connected to at least one respective electric circuit of the plant to control a selective opening/closing thereof; at least one actuator (9) adapted to interact with said at least one contact unit (8) to promote a selective opening/closing of the respective circuits thereby; and means (10) for anchoring said at least one contact unit (8) to said actuator (9); wherein said anchoring means (10) comprise a containment member (11) adapted to contain said at least one contact unit (8) and anchorable to said closing panel (3) into said box-shaped body (2) for stably securing said at least one contact unit (8) on said actuator (9), and wherein said containment member (11) is substantially box-shaped and envelopes said at least one contact unit (8), said containment member (11) having an upper wall (14) adapted to face said closing panel (3) and a side wall (15) extending from an entire perimeter of said upper wall (14) and closed by a planar bottom wall (16) to define one or more adjacent housings (17) adapted to hold respective contact units (8), said bottom wall (16) having an opening that provides access to said contact units (8).
