ABSTRACT:
A manually operated switch, typically of DIP size, having a slightly deformable over-center cam rotor journalled in a hollow housing. Symmetrical projections on the rotor move two opposed cantilever springs into and out of electrical contact. The deformation of the rotor provides detent action. Stops are not required. Single wiping action occurs upon closing the contacts.
The cantilever springs may be ridged and of unequal length, or not ridged and of equal free length.
