Claims
- 1. A method of forming a switch comprising the steps of:
- (a) providing an upper contact assembly comprising a first electrically insulating body having a first hollow central region and a first electrically conducting member having a depending contact member extending into said first hollow central region, said first conducting member extending externally of said body;
- (b) providing a lower contact assembly comprising a second electrically insulating body having a second hollow central region and a second electrically conducting member having an upwardly extending contact member extending into said second hollow region, said second conducting member extending externally of said body;
- (c) providing a third electrically conducting member electrically insulated from the first and second members and including an aperture aligned to permit at least one of said contact members to pass therethrough;
- (d) providing a pressure responsive snap acting member responsive to predetermined pressure thereagainst to switch from one of an upwardly extending and a downwardly extending condition to the other of said conditions, said snap acting member being positioned over said aperture in said third member and between said depending and upwardly extending contacts; and
- (e) sandwiching said snap acting member and said third member between said upper and lower contact assemblies.
- 2. The method of claim 1 further including the step of removing the portion of one of said first and second electrically conducting member extending externally of its associated body.
- 3. The method as set forth in claim 2 wherein said depending contact member is normally in contact with said snap action member and said upwardly extending contact member is normally out of contact with said snap acting member.
- 4. The method as set forth in claim 3 wherein said upper contact member further includes a recess and an o-ring disposed in said recess and extending out of said recess.
- 5. The method as set forth in claim 4 wherein one of said upper and lower contact assemblies includes outwardly extending legs and the other of said upper and lower contact assemblies includes grooves for fixedly receiving said legs therein.
- 6. The method as set forth in claim 3 wherein one of said upper and lower contact assemblies includes outwardly extending legs and the other of said upper and lower contact assemblies includes grooves for fixedly receiving said legs therein.
- 7. The method as set forth in claim 2 wherein said upper contact assembly further includes a recess and an o-ring disposed in said recess and extending out of said recess.
- 8. The method as set forth in claim 7 wherein one of said upper and lower contact assemblies includes outwardly extending legs and the other of said upper and lower contact assemblies includes grooves for fixedly receiving said legs therein.
- 9. The method as set forth in claim 2 wherein one of said upper and lower contact assemblies includes outwardly extending legs and the other of said upper and lower contact assemblies includes grooves for fixedly receiving said legs therein.
