Abstract
Abstract A closure switch operates a bulb that illuminates a compartment in response to the opening and closing, respectively, of the compartment's closure lid. A metal bracket carries the switch and a striker member for a latch carried by the closure lid. The bracket also serves as a current carrying member of the switch and includes a terminal for connection into an electrical circuit, e.g., to ground. A molded plastic housing mounts to the bracket and retains the bulb. The housing includes an integral or "living" hinge that is pivoted from a first to a second position by the latch when the lid is closed. When the lid is open and the hinge member is in its first position, the circuit through the bulb is complete. When the lid is closed, the latch on the lid pivots the hinge to its second position and the circuit is broken.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
273 words
A switch for mounting relative to a compartment having an access opening closable by a closure lid, the closure lid carrying means for latching the closure lid in a closed position, said switch being activated to energize and de-energize a lamp bulb for illuminating the compartment in response to the opening and closing, respectively, of the closure lid, said switch comprising: A. a bracket for mounting relative to the compartment and for connection into an electrical circuit; B. a housing mounted to said bracket, said housing being formed from an insulating material and including i. a lamp bulb receiving portion for receiving and retaining the lamp bulb, and ii. a movable member disposed on said housing so as to be engaged by the latching means on the closure lid and moved from a first position to a second position in response to the closing of the closure lid; C. a first contact member mounted to said housing and including i. a first portion for connection into the electrical circuit, and ii. a second portion for connecting to the bulb; and D. a second contact member mounted to said housing and including i. a first portion for connecting to the bulb, and ii. a second portion carried by said movable housing member for contacting said bracket when said movable housing member is in its first position thereby to complete the electrical circuit through the bulb and energize the bulb, said second portion of said second contact member being movable away from said bracket when said movable housing member is moved to its second position thereby to open the electrical circuit and de-energize the bulb.
Claim 2
Dependent Claim
273 words
A switch for mounting relative to a compartment having an access opening closable by a closure lid, the closure lid carrying means for latching the closure lid in a closed position, said switch being activated to energize and de-energize a lamp bulb for illuminating the compartment in response to the opening and closing, respectively, of the closure lid, said switch comprising: A. a bracket for mounting relative to the compartment and for connection into an electrical circuit; B. a housing mounted to said bracket, said housing being formed from an insulating material and including i. a lamp bulb receiving portion for receiving and retaining the lamp bulb, and ii. a movable member disposed on said housing so as to be engaged by the latching means on the closure lid and moved from a first position to a second position in response to the closing of the closure lid; C. a first contact member mounted to said housing and including i. a first portion for connection into the electrical circuit, and ii. a second portion for connecting to the bulb; and D. a second contact member mounted to said housing and including i. a first portion for connecting to the bulb, and ii. a second portion carried by said movable housing member for contacting said bracket when said movable housing member is in its first position thereby to complete the electrical circuit through the bulb and energize the bulb, said second portion of said second contact member being movable away from said bracket when said movable housing member is moved to its second position thereby to open the electrical circuit and de-energize the bulb.
Claim 3
Dependent Claim
63 words
The switch of claim 1 in which said bracket comprises i. a mounting portion for mounting said bracket relative to the compartment, ii. a terminal portion for connection into the electrical circuit, and iii. a latch striker portion engageable by the lid latching means when the closure lid is moved to its closed position for retaining the closure lid in its closed position.
Claim 4
Dependent Claim
19 words
The switch of claim 2 in which said bracket is formed as an integral unit from a rigid metal.
Claim 5
Dependent Claim
25 words
The switch of claim 1 in which said first and second contact members are each formed as an integral unit from a spring metal material.
Claim 6
Dependent Claim
58 words
The switch of claim 1 in which the bulb is of the type including a base having a tip and a shell that are connectable into the electrical circuit to energize the bulb and in which the second portion of said first contact member is disposed within said housing to resiliently contact the tip of the bulb base.
Claim 7
Dependent Claim
30 words
The switch of claim 1 in which the first position of said first contact member is formed as a terminal for connection to a voltage source in the electrical circuit.
Claim 8
Dependent Claim
54 words
The switch of claim 1 in which the bulb is of the type including a base having a tip and shell that are connectable into the electrical circuit to energize the bulb and in which the first portion of said second contact member is disposed for resiliently contacting the shell of the bulb base.
Claim 9
Dependent Claim
23 words
The switch of claim 2 in which the terminal portion of said bracket is formed as a terminal for connection to electrical ground.
Claim 10
Dependent Claim
