ABSTRACT:
An electromagnetic switching device comprises a solenoid actuator 18 including an armature 22, the reciprocating movement of which is converted by a pair of levers 25, 26 to a reciprocating counter-movement of a contact slider 16 extending parallel thereto. The contact slider 16 is provided with bridge contacts 17b which cooperate with stationary contacts 12 fixed within a base 10. Outwardly projecting guide members 30 which are provided on the solenoid actuator 18 and extend through recesses 31 formed in the levers 25, 26 serve to support the latter. Upon assembly, the solenoid actuator 18 is equipped with the levers 25, 26 and the contact slider 16 to form an assembly unit which is inserted as it is into the base 10. In this assembly unit, the levers 25, 26 are retained in position so that the assembly step can be performed easily and rapidly without any mounting aids.
