Abstract
Abstract A toggle lever switch having a central longitudinal bore in the outer handle for housing an LED (light emitting diode) with terminals extending down through the handle and bent laterally outward along the pivotal axis through lateral holes in the spherical portion of the toggle lever to engage inwardly biased stationary terminals extending up through the bushing adjacently facing the lateral holes. The LED terminals themslves are used as the commutating connectors. Commutation means are provided for spacing the LED terminals and for maintaining good electrical contact with the stationary terminals, and in preferred form comprises an insulating plug having a pigtail. This plug is initially placed at the root of the terminals next to the LED, whereafter the terminals are pinched together in parallel overlapped relation so that they will fit through the bore on the handle and are inserted therethrough until the lateral ends thereof enter the lateral holes and the pigtail comes out through a radial hole extending from the junction of the bore and the lateral holes. The pigtail is then pulled to slide the plug down to spread the lateal ends of the LED terminals and ensure good electrical contact thereof with the stationary terminals.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
158 words
In a switch having a housing enclosing contacts, the combination comprising: a bushing at the top of said housing; a toggle lever extending through said bushing and having a middle portion pivotally mounted in said bushing, an inner portion for operating said contacts, and an outer portion having a central bore extending longitudinally therethrough to communicate with a pair of lateral holes extending oppositely outwardly through said middle portion coaxial with the pivotal axis of said toggle lever; a pair of stationary terminals extending up through said bushing adjacent the outer ends of said lateral holes; a light source having a pair of terminals extending longitudinally in said bore with bent portions extending laterally outwardly through said lateral holes to engage said stationary terminals, and means maintaining electrical contact between said stationary terminals and said bent portions of said light source terminals and maintaining said light source terminals in spaced-apart relation to prevent shorting of said light source.
Claim 2
Dependent Claim
158 words
In a switch having a housing enclosing contacts, the combination comprising: a bushing at the top of said housing; a toggle lever extending through said bushing and having a middle portion pivotally mounted in said bushing, an inner portion for operating said contacts, and an outer portion having a central bore extending longitudinally therethrough to communicate with a pair of lateral holes extending oppositely outwardly through said middle portion coaxial with the pivotal axis of said toggle lever; a pair of stationary terminals extending up through said bushing adjacent the outer ends of said lateral holes; a light source having a pair of terminals extending longitudinally in said bore with bent portions extending laterally outwardly through said lateral holes to engage said stationary terminals, and means maintaining electrical contact between said stationary terminals and said bent portions of said light source terminals and maintaining said light source terminals in spaced-apart relation to prevent shorting of said light source.
Claim 3
Dependent Claim
22 words
The switch according to claim 1 wherein said means comprises an insulating member situate in said bore between said light source terminals.
Claim 4
Dependent Claim
43 words
The switch according to claim 2 wherein said middle portion of said toggle lever has a third hole extending outwardly from the junction of said bore and said lateral holes, and wherein said insulating member has a tail portion in said third hole.
Claim 5
Dependent Claim
30 words
The switch according to claim 2 wherein said insulating member resiliently biases said light source terminals laterally outwardly to provide electrical contact between said bent portions and said stationary terminals.
Claim 6
Dependent Claim
44 words
The switch according to claim 2 wherein said middle portion has a third hole extending outwardly from the junction of said bore and said lateral holes for insertion of said insulating member through said third hole into said bore between said light source terminals.
Claim 7
Dependent Claim
45 words
The switch according to claim 1 wherein the length of each of said bent portions of said light source terminals is less than the width of said longitudinal bore whereby said light source terminals may be inserted into said bore from the outer end thereof.
Claim 8
Dependent Claim
23 words
The switch according to claim 1 wherein said means comprises inherent resiliency in said light source terminals biasing said bent portions laterally outwardly.
Claim 9
Dependent Claim
23 words
The switch according to claim 1 wherein said stationary terminals are laterally inwardly biased against said bent portions of said light source terminals.
Claim 10
Dependent Claim
15 words
The switch according to claim 1 wherein said light source is a light emitting diode.
Claim 11
Dependent Claim
36 words
The switch according to claim 9 wherein said diode is mounted in said bore and wherein said switch further comprises a light-transmissive cap mounted to the outer end of said outer portion of said toggle lever.
Claim 12
Dependent Claim
28 words
The switch according to claim 9 wherein said diode is mounted in said bore and protrudes beyond the outer end of said outer portion of said toggle lever.
Claim 13
Dependent Claim
23 words
The switch according to claim 9 wherein said diode is mounted to the outer end of said outer portion of said toggle lever.
Claim 14
Dependent Claim
68 words
The switch according to claim 1 wherein the length of each of said bent portions of said light source terminals is less than the width of said bore whereby said light source terminals may be laterally deflected for insertion into said bore from the outer end thereof, and wherein said means comprises an insulating member situate in said bore between said light source terminals proximate said lateral holes.
Claim 15
Dependent Claim
91 words
The switch according to claim 13 wherein said middle portion of said toggle lever has a third hold extending outwardly from the junction of said bore and said lateral holes, and wherein said insulating member has a tail portion threadable through said third hole during assembly such that said insulating member may be disposed adjacent said light source during insertion of said light source terminals into said bore, whereafter said tail portion may be pulled to slide said insulating member longitudinally in said bore to a position proximate said lateral holes.
