Abstract

Dispositif de commande d'un appareil électrique interrupteur, comportant un électroaimant de commande muni d'une palette mobile entre une position repos et une position travail sous l'action d'une bobine (20), un contact auxiliaire (10) dans un circuit d'alimentation de la bobine (20) et des moyens mécaniques (30) couplés avec la palette mobile pour actionner le contact auxiliaire. Les moyens mécaniques comportent deux ressorts de compression et un coulisseau coopérant avec le contact auxiliaire pour effectuer une hystérésis de telle sorte que l'état ouvert du contact auxiliaire est obtenu à la fin de la course amenant la palette mobile en position travail et que l'état fermé du contact auxiliaire est obtenu à la fin de la course amenant la palette mobile en position repos.

Figure 00000001
Device for controlling a switch electrical apparatus, comprising a control electromagnet provided with a pallet movable between a rest position and a working position under the action of a coil (20), an auxiliary contact (10) in a circuit supplying the coil (20) and mechanical means (30) coupled with the movable pallet to actuate the auxiliary contact. The mechanical means comprise two compression springs and a slide cooperating with the auxiliary contact to perform a hysteresis so that the open state of the auxiliary contact is obtained at the end of the stroke bringing the movable pallet into working position and that the closed state of the auxiliary contact is obtained at the end of the stroke bringing the movable pallet to the rest position.
