Abstract
The switch includes an electromagnet (9) with a moving core (10) which is retracted when voltage is applied. A configuration of three levers (11, 12, 13) which are fixed together in pairs when the switch is cocked. The first lever (11) is integral with the rotary control shaft (3). The second lever (12) pivots on a stationary middle shaft (23) due to the respective actions of the core being released and of an antagonistic spring (15). The third lever (13) pivots on the end shaft (28), is provided with a return spring (16) and holds the control shaft (3) and the first lever (11) in position by being fixed to the other two levers. The third lever which has a middle lock projection (29) for the first lever also has a transversal passage (24) with a notch (27) in which the free end (25) of the second lever (12) can move, said free end itself having a hooked portion (26) which co-operates with the notch (27) in the tripped position and allowing manual or automatic return to the rest position.
