Title:
LOCKING MECHANISM FOR MUTUAL MECHANICAL COOPERATION FOR TWO ADJACENT SWITCH UNITS
Document Type and Number:
Japanese Patent JPS60121631
Kind Code:
A
Abstract:
Two similar switch apparatuses are mounted in switching direction at equidirectional closing direction onto a base. Each apparatus has an extension which is movable together with the armature of the corresponding apparatus and which extends in a respective L-coulisse of a two-armed lever placed on a stub shaft of a casing of one of the switch apparatuses to pivot thereabout. If one of the switch apparatuses carries out its switch closing operation, its extension moves in a path section of the coulisse at an acute angle relative to the direction of radius, causing a counterclockwise pivoting movement of the lever. Conclusively, the extension of the other switch apparatus will be caused to be located into a path section of its coulisse extending circularly around the stub such that the latter extension is blocked, preventing a switching movement. The extremely simple design and the equidirectional position of the switch apparatuses allows an economically advantageous arrangement and mounting and prevents a mixup or confusion when connecting the switch apparatuses. Furthermore an exclusively mechanical interlocking of a switch apparatus is possible already at the beginning of the switching movement of the other apparatus such that the holding force of the magnets is practically meaningless.
