Momentary contact single pole switch

Claim 2

A momentary-contact single-pole electrical switch comprising: a. a substrate having two major surfaces with an opening therethrough extending from one of said major surfaces to the other major surface, said substrate including a plurality of electrically conductive terminal members on said one major surface approximately equidistant from said opening; b. a non-conductive pushbutton actuator having a button and two legs with each of said legs having a retention means on the end thereof, said legs extending through said opening with said button facing said one major surface and with said retention means extending beyond the edge of said opening on said other major surface; and c. conductive biasing means between said button and said one major surface being retained by said legs with said conductive biasing means normally biasing itself and said button away from saiD terminal members; wherein d. depression of said actuator button applies a force against said conductive biasing means causing said conductive biasing means to make electrical contact with said terminal members to complete a conductive path between said terminal members.

Claim 3

The electrical switch according to claim 1 wherein said conductive biasing means is an integral conductive curved spring member.

Claim 4

The electrical switch according to claim 2 wherein said curved spring member is a curved spring washer having an opening therein with said legs extending through such opening.

Claim 5

The electrical switch according to claim 2 wherein said curved spring member is comprised of beryllium copper.

Claim 6

The electrical switch according to claim 1 wherein said substrate is a printed circuit board.

Claim 7

The electrical switch according to claim 5 wherein said substrate includes printed wiring formed on said one major surface and said terminal members are termination points of said printed wiring.

Claim 8

The electrical switch according to claim 5 wherein said substrate includes printed wiring formed on said other major surface and said terminal members include feedthrough conductors extending through openings in said substrate and being electrically connected to said printed wiring on said other major surface of said substrate.

Claim 9

The electrical switch according to claim 1 wherein said pushbutton actuator is comprised of plastic.

Claim 10

A momentary-contact single-pole electrical switch comprising: a. a substrate having two major surfaces and an opening therethrough extending from one of said major surfaces to the other of said major surfaces, said substrate including a plurality of electrically conductive terminal members extending on said one major surface approximately equidistant from the center of said opening; b. a non-conductive pushbutton actuator having a button and two integral legs with each leg having an integral retainer tab on the end thereof, said legs extending through said substrate opening with said pushbutton actuator being retained by said tabs which extend beyond the edge of the opening on said other major surface; and c. an electrically conductive spring member positioned between said button and said one major surface and having an opening therein with said legs extending through such opening, said spring member being positioned with respect to said terminal members such that the spring member is normally curved or bent away from said terminal members and biases said button; wherein d. depression of said pushbutton actuator causes said button to apply a force against said spring member causing said spring member to make electrical contact with said terminal members to complete a conductive path between said terminal members.

Claim 11

A momentary-contact single-pole electrical switch comprising: a. a substrate having two major surfaces and an opening therethrough extending from one of said major surfaces to the other of said major surfaces, said substrate including a plurality of electrically conductive terminal members extending on said one major surface approximately equidistant from the center of said opening; b. a non-conductive pushbutton actuator having a button and two integral legs with each leg having an integral retainer tab on the end thereof, said legs extending through said substrate opening with said pushbutton actuator being retained by said tabs which extend beyond the edge of the opening on said other major surface; and c. an electrically conductive spring member positioned between said button and said one major surface and having an opening therein with said legs extending through such opening, said spring member being positioned with respect to said terminal members such that the spring member is normally curved or bent away from said terminal members and biases said button; wherein d. depression of said pushbutton actuator causes said button to apply a force against said spring member causing said spring member to make electrical contact with said terminal members to complete a conductive path between said terminal members.

Claim 12

The electrical switch according to claim 9 wherein said openings through said substrate and spring member are non-circular and are maintained in position by said legs.

Claim 13

The electrical switch according to claim 9 wherein said legs are flexible and wherein said actuator pushbutton is insertable or removable from retention by said tabs and substrate by squeezing together said flexible legs.
