Abstract
Abstract This invention is an improved electrical switch in which the housing is molded in one piece with the terminals being thereafter slidably inserted into an arcuate in cross section slot with a cover plate permanently retaining the same. This switch is so designed that even miniature configurations are capable of handling current loads without danger of internal arcing.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
153 words
An electrical type switching means comprising: a switch housing having side wall means and a bottom means; a plurality of slot-like openings provided in the interior portion of said side wall means, the interior edge of each said slots being more constricted in cross section than the remainder of said slot; openings in said bottom means a parallel alignment with each of said slot means; electrically conductive terminal means slidingly mounted into and retained by said slot means and projecting outwardly through said openings in said bottom, the slot engaging portion of each of said terminal means being generally arcuate in cross section and convexingly disposed relative to the interior side wall means of said housing; actuator motivated, electrically conductive contact means for making and breaking contact between said terminals; and a cover means for enclosing said housing and retaining said terminals within said slots whereby an improved electrical switch means is provided.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
17 words
The switch means of claim 1 wherein the cover means is ultrasonically welded to said housing means.
Claim 4
Dependent Claim
33 words
The switch means of claim 2 wherein a raised flash guard is provided on said housing juxtaposed to said cover to prevent undesirable weldment material entering said housing during the ultrasonic welding process.
Claim 5
Dependent Claim
26 words
The switch means of claim 1 wherein mounting supports are provided on the exterior of said bottom means whereby more stable switch mounting can be accomplished.
Claim 6
Dependent Claim
23 words
The switch means of claim 4 wherein said mounting supports are disposed exterior of said terminal means to protect the same from damage.
Claim 7
Dependent Claim
33 words

Claim 10
Dependent Claim
36 words
The swtich means of claim 7 wherein the slidingly mounted contact means includes a non-conductive partition slidely mounted within a longitudinal groove in the interior side of said bottom means whereby internal electrical arcing is reduced.
Claim 11
Dependent Claim
13 words
The switch means of claim 1 wherein the contact means is rotatively mounted.
Claim 12
Dependent Claim
21 words
The switch means of claim 10 wherein said rotatively mounted contact includes at least one spring biased, electrically conductive contact means.
Claim 13
Dependent Claim
17 words
The switch means of claim 11 wherein said rotatively mounted contact means is a disc shaped member.
