An electrical switch provides a center contact moving between two outer contacts, at least one of which is mounted on a lever. In the event of a contact weld forming between the center contact and the lever mounted contact, unison motion of the lever mounted contact following the center contact during switching causes a strong shear force tending to break the weld. In one embodiment, a fulcrum wall striking the lever of the lever mounted contact causes increased angulation between the contacts so that unison motion rotates and peels the contacts apart.
