Claim 8

A switch according to claim, 6 wherein said second and third contact surfaces of said second and third pads, respectively, lie in a common plane, said electrical contacts of said first, second and third pads lying in a common plane substantially perpendicular to said plane containing said second and third contact surfaces, said spring portions lying in a plane spaced forwardly from and lying generally parallel to said plane containing said second and third contact surfaces.

Claim 9

A switch according to claim 5 wherein said spring portions include indentations therealong projecting toward said contact surfaces.

Claim 10

A switch according to claim 5 wherein said second and third pads comprise generally U-shaped elements disposed about respective side portions of said core, said contact surfaces of said second and third pads being disposed between side portions of said core and said spring portions for engagement by said spring portions upon deflection thereof toward said contact surfaces, respectively, second and third pads lying in a plane generally parallel with said electrical contact of said first pad.

Claim 11

A switch according to claim 1 wherein said core has a central enlargement intermediate opposite ends thereof and has a projection at least along a central front portion thereof, said connector front portion overlying said projection of said central front portion of said core with said spring portions lying on opposite sides of said connector front portion and normally spaced from respective side portions of said core on opposite sides of said central portion thereof, said connector having a portion overlying said enlargement providing a substantial area for pick-up by a vacuum cup and placement on a circuit board.

Claim 12

A switch according to claim 5 wherein said connector front portion includes a pair of collapsible dents projecting toward said core and responsive to respective displacement of said spring portions into engagement with said core to collapse and emit an audible signal representing completion of said circuits.

Claim 13

A double switch comprising: an elongated core formed of electrical insulating material and having intermediate and end portions therealong; a connector formed of electrically conductive material and having a front face portion overlying a front surface of said intermediate portion of said core, said front face portion including a pair of spring portions spaced from one another and forwardly of said end portions of said core and movable toward and away from said end portions, said connector including a generally cross-shaped element having legs in generally parallel planes on opposite sides of said front face portion overlying opposite faces of said core along said intermediate portion thereof with one of said legs forming a first pad having an electrical contact; the opposite faces of said intermediate portion of said core being inset for receiving said legs, respectively, whereby said connector is clamped about the intermediate portion of said core; second and third pads carried by said core adjacent said opposite end portions thereof, said second and third pads having respective electrical contacts and second and third contact surfaces for engagement by said spring portions, respectively, whereby movement of said spring portions toward and into engagement with said second and third contact surfaces completes circuits between said first contact and said second contact, and said first contact and said third contact, respectively.

Claim 14

A double switch comprising: an elongated core formed of electrical insulating material and having intermediate and end portions therealong; a connector formed of electrically conductive material and having a front face portion overlying a front surface of said intermediate portion of said core, said front face portion including a pair of spring portions spaced from one another and forwardly of said end portions of said core and movable toward and away from said end portions, said connector including a generally cross-shaped element having legs in generally parallel planes on opposite sides of said front face portion overlying opposite faces of said core along said intermediate portion thereof with one of said legs forming a first pad having an electrical contact; the opposite faces of said intermediate portion of said core being inset for receiving said legs, respectively, whereby said connector is clamped about the intermediate portion of said core; second and third pads carried by said core adjacent said opposite end portions thereof, said second and third pads having respective electrical contacts and second and third contact surfaces for engagement by said spring portions, respectively, whereby movement of said spring portions toward and into engagement with said second and third contact surfaces completes circuits between said first contact and said second contact, and said first contact and said third contact, respectively.

Claim 15

A switch according to claim 12 wherein the electrical contacts of said first, second and third pads lie in a common plane for connection to a flat circuit board.

Claim 16

A switch according to claim 12 wherein said first pad is cantilevered from the switch on a side thereof remote from said front surface portion of said core.

Claim 17

A switch according to claim 12 wherein said core has a forward projection in part defining said front surface thereof, said connector front face portion overlying said core front surface with said spring portions lying on opposite sides of said connector front face portion and normally spaced from respective end portions of said core on opposite sides of said intermediate portion thereof.

Claim 18

A switch according to claim 15 wherein said contact surfaces of said second and third pads are disposed between side portions of said core and said spring portions for engagement by said spring portions upon deflection thereof toward said contact surfaces, respectively, said electrical contacts of said first, second and third pads lying in a common plane.
