Abstract
A switch housing in which a cylindrical hollow body of the housing has attached wing elements, each in the form of a partial cylinder and resiliently movable radially and circumferentially of the body, varying the overall transverse dimension of the housing so that the housing may be removably inserted into cavities of various sizes or non-uniform bore, with the wing elements biased to exert outward force against the interior of a cavity. The wing elements may define exterior threads to aid in retention of the housing in a cavity, and a head of the housing preferably defines a chamfered radially extending flange to limit insertion of the housing, and grooves to aid in removing the housing from a cavity.
