Abstract
A protective switch device such as a contactor/circuit-breaker comprises double-contact switch poles. Contact bridges are housed in a mobile support. Slide members guided in slots of the support and commanded by a tripping mechanism can be applied to the bridges. The mobile support can be actuated by a solenoid without the contact pressure springs transmitting any reaction force to the armature of the solenoid.
