A trip system for an electrical switch comprises first and second magnetic circuits are formed by a yoke and an armature. The second magnetic circuit has a magnetic resistance in a first position of the armature, which resistance is higher than that of the first magnetic circuit and increases in the movement of the armature from the first to the second position.

Trip system for an electrical switch having a favorable force-path-characteristic

Switch with at least one set of interacting contacts which is accommodated in the switch housing and can be seen through a transparent window. The contacts are arranged on the free ends of current-carrying strips which run towards the window. At least one of the strips has U-shaped section adjacent to its contact, the opening of the U-shaped section facing away from the window. A plate made from magnetizable material is arranged between the limbs of the U-shaped section of at least one strip.
