OPERATING DEVICE FOR POWER SWITCH DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/199303
Kind Code:
A1
Abstract:
This operating device for a power switch device comprises: an output lever coupled to a mobile contact of the power switch device; a torsion bar releasing a stored force during circuit-opening by the power switch device, and causing the output lever to rotate in an anti-clockwise direction in order to drive the mobile contact in a circuit-opening direction; an open circuit latch capable of engaging the output lever in such a manner as to cause the stored force of the torsion bar to be maintained; a cam (2) rotating during circuit-closing by the power switch device, abutting against the output lever, causing the output lever to rotate in the clockwise direction, and driving the mobile contact in the circuit-closing direction; a torsion bar causing the cam to rotate by releasing stored force therefrom during circuit-closing; and a closed circuit latch (3) capable of engaging the cam (2) in such a manner as to cause the stored force of the torsion bar to be maintained. The cam (2) has a pair of cam elements (2a, 2b) facing one another; a pin (1) whereof both extremity portions are rotatably supported by the cam elements (2a, 2b); and a bolt (42) for fastening the cam elements (2a, 2b) together.
