Abstract
Abstract A momentary switch of miniature size having a block of dielectric material providing a substrate and a pair of circuit paths defined by uninsulated wires mounted to the block, the ends of the wires forming switch poles, a resilient spring made from a wire mounted on the block, one end of the resilient spring normally engaged on a first switch pole, and a plunger reciprocatingly received in an opening of said block and displaceable into engagement on the spring to urge it forcefully into engagement with the second pole in opposition to the resilient action of said spring to interrupt a first electrical circuit through one of the wires and to complete a second electrical circuit through the second wire.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
179 words
A switch, comprising: a dielectric base having a pair of pockets, a pair of wires having first ends thereof embedded in said base, first and second recesses in said base, second ends of said wires being mounted in mutual spaced relationship within the first recess of said base, medial portions of said wires having bight portions mounted in mutual spaced relationship within the second recess of said base, first and second springs having coiled central portions received in the respective pockets, a first end of each spring protruding from a corresponding pocket and embedded in said base, a second end of said first spring being received between said second ends of said wires and being capable of resilient deflection into electrical engagement with each of said second ends of said wires, a second end of said second spring being received between said bight portions and being capable of resilient deflection into electrical engagement with each of said bight portions, and actuator means received by said base for engaging and resiliently deflecting a corresponding second end of a corresponding spring.
Claim 2
Dependent Claim
179 words
A switch, comprising: a dielectric base having a pair of pockets, a pair of wires having first ends thereof embedded in said base, first and second recesses in said base, second ends of said wires being mounted in mutual spaced relationship within the first recess of said base, medial portions of said wires having bight portions mounted in mutual spaced relationship within the second recess of said base, first and second springs having coiled central portions received in the respective pockets, a first end of each spring protruding from a corresponding pocket and embedded in said base, a second end of said first spring being received between said second ends of said wires and being capable of resilient deflection into electrical engagement with each of said second ends of said wires, a second end of said second spring being received between said bight portions and being capable of resilient deflection into electrical engagement with each of said bight portions, and actuator means received by said base for engaging and resiliently deflecting a corresponding second end of a corresponding spring.
Claim 3
Dependent Claim
40 words
The structure as recited in claim 1, wherein, said base is arcuate to fit within a watch case, and said actuator means for deflecting said second end of a corresponding spring is a watch stem reciprocatingly received in said base.
