<p>One end of the push-button carries an elastically deformable strip whose other end is free. A lever operates a moving contact cooperating with a stationary contact in the switch housing. Two elastic elements are incorporated, one for lifting the depressed push-button and the other one for the moving contact. The lever is in the form of a rigid magnetisable armature (17), pivoting in the housing (9, 10) and cooperating with an electromagnet (14, 15). The latter coil (15) is fed via the switch output (4) and a bimetal switch (7) acting as an overload detector and forming a holder for the armature. The latter is engaged by a rocker (5) in order to effect its lifting from the electromagnet.</p> |
