Abstract
Abstract A plunger which opens and closes a switch is actuated by a hollow switch button which is trapped between a switch housing and a post which carries the plunger. An edge of the post bearing against the inside corner of the hollow button and the chamfered ends of the button flanges bearing against the intersection of the open end housing walls and a rim extending from the walls provide the button pivot axis to actuate the plunger. The switch includes two resilient blades one of which is longer than the other. One end of each blade is fixed with their distal ends pointed toward and overlapping each other.

Independent Claim
77 words
A door switch comprising a housing having sidewalls and an open end, a post carried in said housing, a plunger carried by said post and engaging a switch means carried in said housing to open and close same, a switch button actuating said plunger carried in said open end and trapped between said post and said housing, an edge of said post providing a pivot axis against which said switch button is pivoted to actuate said plunger.
Claim 2
Dependent Claim
77 words
A door switch comprising a housing having sidewalls and an open end, a post carried in said housing, a plunger carried by said post and engaging a switch means carried in said housing to open and close same, a switch button actuating said plunger carried in said open end and trapped between said post and said housing, an edge of said post providing a pivot axis against which said switch button is pivoted to actuate said plunger.
Claim 3
Dependent Claim
29 words
A door switch according to claim 1 wherein a gap is provided between said post and said housing and said button includes a first flange extending into said gap.
Claim 4
Dependent Claim
20 words
A door switch according to claim 2 wherein said first flange is radiused at its end extending into said gap.
Claim 5
Dependent Claim
27 words
A door switch according to claim 2 wherein said button includes a second flange extending from two of its sides and engaging a rim of said housing.
Claim 6
Dependent Claim

Claim 7
Dependent Claim
76 words
A door switch comprising a housing having an open end, partition means dividing said housing into two compartments, switch means carried in one of said two compartments, switch actuator means carried in the other of said two compartments and extending through said partition means to actuate said switch means, said switch actuator means including a pivoting member carried in said open end and pivoted against a pivot axis provided by an edge of said partition means.
Claim 8
Dependent Claim
76 words
A door switch comprising a housing having an open end, partition means dividing said housing into two compartments, switch means carried in one of said two compartments, switch actuator means carried in the other of said two compartments and extending through said partition means to actuate said switch means, said switch actuator means including a pivoting member carried in said open end and pivoted against a pivot axis provided by an edge of said partition means.
Claim 9
Dependent Claim
130 words
A door switch comprising: (a) a housing, (b) means dividing said housing into first and second compartments, (c) a button and a plunger carried in said first compartment with said plunger extending into said second compartment, (d) a switch carried in said second compartment including a first resilient contact blade of a first length, a second resilient contact blade of a second length substantially longer than said first resilient contact blade, each of said first and second resilient contact blades fixed at an end and having the distal end of said first resilient blade overlapping said second resilient blade, an aperture in said first resilient blade, said plunger extending through said aperture to engage said second resilient blade to selectively engage and disengage same from said first resilient contact blade.
Claim 10
Dependent Claim
130 words
A door switch comprising: (a) a housing, (b) means dividing said housing into first and second compartments, (c) a button and a plunger carried in said first compartment with said plunger extending into said second compartment, (d) a switch carried in said second compartment including a first resilient contact blade of a first length, a second resilient contact blade of a second length substantially longer than said first resilient contact blade, each of said first and second resilient contact blades fixed at an end and having the distal end of said first resilient blade overlapping said second resilient blade, an aperture in said first resilient blade, said plunger extending through said aperture to engage said second resilient blade to selectively engage and disengage same from said first resilient contact blade.
