ABSTRACT:
A magnetic electrical contact system comprising first and second electrical members connected in two different electrical circuits. One of these members is a power member and the other member a pick-up member. A plurality of closely spaced plungers are mounted at the surface of one member and are movable between a normal inoperative position and an operative position. As the pick-up member is moved over the surface of the power member, plungers engaged by the pick-up member are moved thereby to their operative positions. When a plunger is in its operative position the electrical circuit of one member is connected to that of the other member.
