Abstract
The double switch includes a core formed of insulating material and a connector formed of electrically conductive material. The connector extends along a front face of the core and has spring portions overlying a pair of isolated terminals secured on the opposite ends of the core. The connector includes a first pad lying in a plane common to second and third pads such that the switch can be mounted on a printed circuit board. By deflecting one or more of the spring portions into the second or third pad, an electrical circuit is completed between the first pad and the selected pad.
Claims19
A double switch comprising:
- an elongated core formed of electrical insulating material;
- a connector formed of electrically conductive material and having a front portion along a length of said core, said front portion including a pair of spring portions spaced from one another and forwardly of said core and movable toward and away from said core, said connector including a first pad having a first electrical contact;
- and
- second and third pads carried by said core and having respective second and third electrical contacts and respective 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, the electrical contacts of said first, second and third pads lying in a common plane for connection to a flat circuit board.
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.
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.
