Abstract
Abstract A pushbutton switch having at least one slider operated by a pushbutton. The slider has a projection to engage a blade carrying a movable contact and move the blade and the movable contact whereby a scrubbing action is provided between the movable contact and a stationary contact when the two contacts are in engagement. The projection is beveled adjacent its distal end so that engagement between the projection and the blade is prevented when the two contacts are not in engagement.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
144 words
A pushbutton switch comprising: a hollow housing, at least one manually operable pushbutton projecting from said housing, at least one slider disposed within said housing and adapted for movement in response to movement of said pushbutton, at least one stationary electrical contact within said housing, at least one resilient blade within said housing having a fixed end and a free end, and at least one movable contact secured to said blade adjacent said free end, said slider having means to move said blade and thus move said movable contact out of engagement with said stationary contact in response to movement of said slider in one direction, said slider further having means to move said movable contact relativE to said stationary contact to provide a scrubbing action between said contacts in response to movement of said slider in a direction opposite to said one direction.
Claim 2
Dependent Claim
144 words
A pushbutton switch comprising: a hollow housing, at least one manually operable pushbutton projecting from said housing, at least one slider disposed within said housing and adapted for movement in response to movement of said pushbutton, at least one stationary electrical contact within said housing, at least one resilient blade within said housing having a fixed end and a free end, and at least one movable contact secured to said blade adjacent said free end, said slider having means to move said blade and thus move said movable contact out of engagement with said stationary contact in response to movement of said slider in one direction, said slider further having means to move said movable contact relativE to said stationary contact to provide a scrubbing action between said contacts in response to movement of said slider in a direction opposite to said one direction.
Claim 3
Dependent Claim
34 words
The invention of claim 1 wherein said slider has a cam surface adjacent one edge for engagement by said pushbutton whereby said slider is moved in said opposite direction when said pushbutton is depressed.
Claim 4
Dependent Claim
38 words
The invention of claim 2 wherein said means to move said blade comprises a second cam surface adjacent an edge of said slider opposite said one edge and adapted to engage said blade upon movement of said slider.
Claim 5
Dependent Claim
45 words
The invention of claim 3 wherein said means to move said movable contact relative to said stationary contact comprises a projection on the edge of said slider which said second cam surface is adjacent to, said projection being adapted to engage and move said blade.
Claim 6
Dependent Claim
35 words
The invention of claim 4 wherein said projection is spaced from said second cam surface whereby said movable contact is allowed to engage said stationary contact prior to engagement of said blade by said projection.
Claim 7
Dependent Claim
104 words
A pushbutton switch comprising: a hollow housing, at least one manually operable pushbutton projecting from said housing, at least one slider disposed within said housing and adapted for movement in response to movement of said pushbutton, at least one stationary electrical contact within said housing, at least one resilient blade within said housing having a fixed end and a free end, and at least one movable contact secured to said blade adjacent said free end, said slider having means to engage and move said blade when said stationary contact is in engagement with said movable contact to provide a scrubbing action between said contacts.
Claim 8
Dependent Claim
104 words
A pushbutton switch comprising: a hollow housing, at least one manually operable pushbutton projecting from said housing, at least one slider disposed within said housing and adapted for movement in response to movement of said pushbutton, at least one stationary electrical contact within said housing, at least one resilient blade within said housing having a fixed end and a free end, and at least one movable contact secured to said blade adjacent said free end, said slider having means to engage and move said blade when said stationary contact is in engagement with said movable contact to provide a scrubbing action between said contacts.
