Claims
- 1. A method of making a pressure sensitive switch comprising the steps of:
- applying an array of substantially parallel, spaced-apart electrically conductive bands to a surface of a first flat flexible member;
- applying an array of substantially parallel, spaced-apart electrically conductive bands to a surface of a second flat flexible member, said array including a conductive input lead connected to selected ones of said second member conductive bands and a conductive output lead connected to others of said second member conductive bands;
- applying an array of substantially parallel, spaced-apart dielectric bands narrower than said conductive bands to said surface of said second member and traversing said first member conductive bands;
- cutting an opening through a third flat flexible member;
- laminating said first, second and third members together with said conductive arrays traversing said opening and each other and said dielectric array being diagonally aligned with alternate overlapping points of said conductive arrays and partially separating said conductive arrays from electrical contact therebetween at said alternate overlapping points;
- whereby said upper and lower members resiliently flexibly permit said overlapping points of said arrays of conductive bands to close into and open out of electrical contact therebetween upon exertion and removal, respectively, of a threshold external compressive force to and from said opening.
- 2. A method according to claim 1, said steps of applying conductive bands comprising screen painting conductive ink.
- 3. A method according to claim 1, said step of applying dielectric bands comprising screen painting dielectric ink.
- 4. A method according to claim 1, said step of laminating comprising heat sealing said members together.
