Abstract
Abstract A manually actuated momentary switch completes an electrical circuit for lighting a low voltage indicator light advantageously used for testing circuit continuity. The switch and indicator light are in combination within a miniature size housing having depending electrical terminals for pluggable connection on a printed circuit board.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
179 words
An indicator light and switch in combination, comprising: a housing, a pair of first contacts in said housing, light means having a pair of electrical leads engaged respectively on said first pair of contacts, said first pair of contacts protruding from said housing to form electrical terminals for pluggable connection externally of said housing, a second pair of contacts in said housing initially in spaced overlapping relationship, a cam displaceably mounted in said housing and having a first portion initially in a single stable position interposed between said second pair of contacts, a second portion on said cam being displaceable upon displacement of said cam to deflect one of said second pair of contacts into engagement with the other of said second pair of contacts to complete an electrical circuit therebetween, said first portion of said cam being displaceable away from said position initially interposed between said second pair of contacts to permit mutual engagement of said contacts, and said second pair of contacts protruding from said housing to provide electrical terminals for pluggable connection externally of said housing.
Claim 2
Dependent Claim
179 words
An indicator light and switch in combination, comprising: a housing, a pair of first contacts in said housing, light means having a pair of electrical leads engaged respectively on said first pair of contacts, said first pair of contacts protruding from said housing to form electrical terminals for pluggable connection externally of said housing, a second pair of contacts in said housing initially in spaced overlapping relationship, a cam displaceably mounted in said housing and having a first portion initially in a single stable position interposed between said second pair of contacts, a second portion on said cam being displaceable upon displacement of said cam to deflect one of said second pair of contacts into engagement with the other of said second pair of contacts to complete an electrical circuit therebetween, said first portion of said cam being displaceable away from said position initially interposed between said second pair of contacts to permit mutual engagement of said contacts, and said second pair of contacts protruding from said housing to provide electrical terminals for pluggable connection externally of said housing.
Claim 3
Dependent Claim
102 words
A momentary switch, comprising a pair of overlapping contacts initially in spaced relationship, a cam having a first integral projecting portion initially in a single stable position interposed between said overlapping contacts and being movable upon displacement of said cam out of said position, said cam having a second integral projecting portion being displaceable upon displacement of said cam of forcibly deflect one of said contacts into engagement with the other of said contacts to complete an electrical circuit path therebetween and said cam being urged to return to said stable position by a return deflection of said one of said contacts.
Claim 4
Dependent Claim
102 words
A momentary switch, comprising a pair of overlapping contacts initially in spaced relationship, a cam having a first integral projecting portion initially in a single stable position interposed between said overlapping contacts and being movable upon displacement of said cam out of said position, said cam having a second integral projecting portion being displaceable upon displacement of said cam of forcibly deflect one of said contacts into engagement with the other of said contacts to complete an electrical circuit path therebetween and said cam being urged to return to said stable position by a return deflection of said one of said contacts.
