Abstract
An electric current switch includes first and second fixed electrical contacts electrically connected; a movable single side electrical contact configured to make single side connection to and disconnect from the first fixed electrical contact for making and breaking electrical current in the electric current switch; and a movable second electrical contact configured to move in contact with the second fixed electrical contact subsequent to the making of current and to disconnect from the second fixed electrical contact before the breaking of electric current. An electrical connection between the movable second electrical contact and the second fixed electrical contact is by a double side contact connecting in a slot.

An electric current switch comprising:
- a first fixed electrical contact;
- a second fixed electrical contact electrically connected with the first fixed electrical contact;
- a movable single side electrical contact configured to make single side connection to and disconnect from the first fixed electrical contact for making and breaking electrical current in the electric current switch;
- and
- a movable second electrical contact configured to move in contact with the second fixed electrical contact subsequent to the making of current and to disconnect from the second fixed electrical contact before the breaking of electric current;
- wherein an electrical connection between the movable second electrical contact and the second fixed electrical contact is by a double side contact connecting in a slot, where one of the movable second electrical contact and the second fixed electrical contact comprises one of the double side contact and the slot and the other one of the movable second electrical contact and the second fixed electrical contact comprises the other one of the double side contact and the slot.
