Abstract
A device having an armature including a main wall; a rotary part intended to be mechanically coupled to a control shaft of an electrical switching unit; a bar integral with the rotary part and able to rotate between a first position and a second position and extending through a slot in the main wall; a position sensor having a movable contact pushed into a retracted position by the bar when the bar is in the first position; a stabilizing device having a resilient strip extending along the slot in order to exert a retaining force on the bar when it is in the first position.
Claims12
A measuring device for detecting the state of an electrical switching unit, wherein said measuring device comprises:
- an armature comprising a main wall;
- a rotary part configured to be mechanically coupled to a control shaft of an electrical switching unit;
- a bar that is able to rotate, integrally with the rotary part, between a first position and a second position, the bar extending through a slot formed in the main wall;
- a position sensor having a movable contact designed to be pushed into a retracted position by the bar when the bar is in the first position and into a released position when the bar is in the second position;
- a stabilizing device having a base integral with the armature and a resilient strip fastened to the base, the strip extending along the slot and being designed to exert a retaining force on the bar when it is in the first position.
