Automatic magnetic switch

An automatic magnetic switch comprising a switch casing having a cover, over-load and short-circuit protection means installed in a first chamber of said switch casing, a manual magnetic switch installed in a second chamber of said switch casing, and a magnetic control means at least partially contained in a sub-casing arranged on the cover, said manual magnetic switch having a first electrically conductive plate or means fixedly mounted within said casing;

• a first electrical contact on said first electrically conductive plate or means;
• a generally rigid and inflexible second electrically conductive plate or means mounted within said casing for movement between engaging and disengaging positions with respect to said first electrically conductive plate or means;
• a second electrical contact on said second electrically conductive plate or means arranged to make and break contact with said first electrical contact in the respective engaging and disengaging positions of said second electrically conductive plate or means;
• resilient means for urging said second electrically conductive plate or means to one of said engaging and disengaging positions;
• said magnetic control means cooperating with said second electrically conductive plate or means and including actuatable means movable proximate to and away from an accessible wall on the opposite side thereof with respect to said second electrically conductive plate or means, said magnetic control means being actuatable by said over-load and short-circuit protection means to thereby automatically switch off power in the magnetic switch upon the occurrence of an over-load or short-circuit condition in said conductive plates and contacts, movement of said actuatable means proximate to said accessible wall moving said second electrically conductive plate or means to the other of said engaging and disengaging positions without material flexure or deformation thereof.
