Abstract
An improvement for retaining wire type contacts of a rotary switch in position upon a stator to facilitate assembly during manufacture. In lieu of previously employed glued or heat sealed construction, the improvement is provided with a resiliently expandable periphery which engages an annular shoulder on the stator element without resort to the use of tools or adhesives.
Claims2
In a wire contact rotary type switch including a stator having a plurality of L-shaped wire contacts positioned in corresponding peripherally located bores, and a retaining ring engaged upon said stator at the periphery thereof to retain said contacts within said bores, the improvement comprising:
- said stator having a peripheral edge portion disposed outwardly of said bores defining a transversely extending shoulder, said retaining ring including a radially extending portion contacting said wire contacts and an axially extending peripheral portion defining a recess, said axially extending portion being radially expandable to enable it to be forced over said shoulder, and upon contraction to engage the same.
