Abstract
A contact breaker assembly including a pivot post, a fixed electrical contact, a heel assembly pivotally mounted on said post and a movable contact carried by said heel assembly and movable into and out of engagement with said fixed contact by pivotal movement of the heel assembly about said post. The heel assembly includes a member having extending therein a bore within which a region of said post is received pivotally to mount the heel assembly on said post. The region of said post is formed with a circumferentially extending recess, and the wall of said bore has a radially inwardly extending projection which is resiliently engaged in said recess. The co-operation of the projection and the recess limits the freedom of axial movement of the heel assembly relative to the post at least in one axial direction.
