Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
123 words
An electrical switch comprising, in combination: an insulated housing; at least one switch means located within said housing; said switch means having actuating means substantially lineraly movable in opposite directions and biased in one of said directions; said housing having integral deformable elastomeric web means overlying said actuating means and flexible in at least said opposite directions; said actuating means being normally biased in said one direction and in said normally biased position engaging and biasing said web in said one direction into a tensioned state from an untensioned state thereof; and upon movement of said actuating means a predetermined distance in a direction opposite said one direction said web means passes from the tensioned state thereof at least to said untensioned state.
Claim 2
Dependent Claim
123 words
An electrical switch comprising, in combination: an insulated housing; at least one switch means located within said housing; said switch means having actuating means substantially lineraly movable in opposite directions and biased in one of said directions; said housing having integral deformable elastomeric web means overlying said actuating means and flexible in at least said opposite directions; said actuating means being normally biased in said one direction and in said normally biased position engaging and biasing said web in said one direction into a tensioned state from an untensioned state thereof; and upon movement of said actuating means a predetermined distance in a direction opposite said one direction said web means passes from the tensioned state thereof at least to said untensioned state.
Claim 3
Dependent Claim
26 words
The combination set forth in claim 1 further characterized in that said switch means includes a plurality of contactor devices axially aligned in a common plane.
Claim 4
Dependent Claim
37 words
An electrical switch as specified in claim 1 wherein upon movement of said actuating means said predetermined distance said web means passes from the tensioned state thereof through said untensioned state and into an oppositely tensioned state.
Claim 5
Dependent Claim
30 words
An electrical switch as specified in claim 3 wherein said untensioned state is at a distance substantially equidistant from the extreme tensioned and oppositely tensioned stae of said web means.
Claim 6
Dependent Claim
24 words
An electrical switch as specified in claim 1 wherein said actuating means engages said web means at a central location of said web means.
