ABSTRACT:
Switch mounting structures have a generally rectangular body switch with oppositely extending planar base extensions, and a housing which defines a pair of spaced-apart slotted mounting entries to receive respective terminal edge portions of a respective one of the base extensions. The terminal edge portions of the base extensions include diagonally opposed pairs of coved portions and recesses, while the housing includes a pair of diagonally opposed proturbences. These proturbences are engaged with said diagonally opposed pair of recesses when said base extensions are rotated relative to said housing from an initial insertion position, where the base extensions are in a slanted orientation relative to the mounting entries, and a mounted position, where the base extensions are in a non-slanted orientation relative to the mounting entries. In such a manner, the switch body and the housing are brought lockable engagement with one another.
