ABSTRACT:
A moving contact assembly to which a moving contact is fitted so as to allow a normally open common fixed contact part to elude the moving contact and axially pass through is mounted detachably on a fixed core. A contact mold having a normally closed fixed contact part and a cap switch provided with a normally open fixed contact part, a normally closed common fixed contact part, and a normally open common fixed contact part are made axially separable. The contact mold is turned 90 degrees in one direction to allow the normally open common fixed contact part to elude the moving contact and axially pass through. Thus, when the contact mold is turned 90 degrees in the other direction to the contact mold's former condition, the moving contact can be positioned within a recessed groove of a common fixed contact.
