Abstract

Proposed is a flat operated electrical switch assembly havina a float which follows the liquid level in a container to which the assembly is in use fittes, the float being mounted with a primary magnet on the wet side of the assembly so that the primary magnet moves upon movement of the float. The primary magnet controls the movement of a secondary switch magnet by magnetic influence through a non-magnetic wall, and the secondary magnet is mounted on the dry side of the assembly and its movement controls the operation of electrical switch contacts, provided by a microswitch of the kind having a button which is depressed against internal return spring action by a reaction applied to a lever pivoted on the microswitch the secondary magnet being coupled with a member which moves and pushes against the lever to depress the microswitch button when the secondary magnet pivots to one end position under the control of the primary magnet. The microswitch lever is made of ferromagnetic material and is attracted by the magnetic field of influence of the secondary magnet such that when the secondary magnet pivots to its end position under the control of the primary magnet, the lever is attracted to and held in a position in which the microswitch button is in its extended position under its internal return spring action.
