A vacuum type circuit interrupter is provided having separable contacts. Each separable contact comprises multiple contact surfaces which are resiliently attached to the main body of the contact by contact surface supporting means. The contact surface supporting means are constructed so that if contact surfaces are welded and if force is applied to separate the contacts, a non-uniform stress distribution is set up in any weld at the contact surfaces. This stress concentration, due to the elastic bending of the contact surface supporting means, aids in breaking the weld and allowing the contacts to separate.
