Title:
MECHANICAL CONTROL DEVICE FOR A SWITCH WITH THREE POSITIONS AND A DEAD CENTRE
Document Type and Number:
WIPO Patent Application WO2006048583
Kind Code:
A3
Abstract:
The invention relates to a control device which can be used to actuate a switch with three positions and two control members, by preventing one control member from being actuated when the other is in the switched position, using two fixed panels (1) between which the control mechanism is placed. According to the invention, control lights (1B and 1C) and an operating light (1A) with determined radii of curvature (L, L1, L2) are positioned such that the operating piece (5) can pivot between two positions relative to a centre position by means of three shafts (5A, 5B, 5C) which form a triangle, the sides of which correspond to the three radii of curvature. The assembly is controlled by two operating shafts (2 and 3), such that the actuation of one of said shafts in the switched position thereof prevents the other shaft from being actuated. The invention is suitable for the switching of medium- and high-voltage electrical installations.
