Human body activated switch

Claim 2

An electrical switch for use by a person and including first and second wires for switchable connection, said switch comprising: a nonconducting support frame mounted upon the persons body; a first electrical contact mounted upon and extending from said frame and connected to said first wire; and contacting means for providing contact between said first contact and a electrically conducting leverarm, said contacting means including a friction device positioned against a portion of the person's skin movable by the person in relation to the support frame and supported by a electrically conducting support arm pivotally mounted upon the support frame and connected thereto to said second wire, said leverarm having a first end mounted in said friction device in electrical contact with the support arm and having a second end positioned adjacent to said first contact wherein movement of the portion of the person's skin by the person will cause contact between the first contact and leverarm resulting in an electrical connection between the first and second wires.

Claim 3

An electrical switch according to claim 1 wherein said first contact includes a conducting loop extending from said frame and enclosing said leverarm between said frame and said loop.

Claim 4

An electrical switch according to claim 2 wherein said friction device is a wheel mounted on said support arm at the wheel axis and having said leverarm mounted on the perimeter of the wheel with the first end extending into said wheel to electrically contact said arm and said second end extending within said first contact loop whereby movement of the persons skin causes an actual rotation of the wheel resulting in movement of said leverarm within said first contact loop.

Claim 5

An electrical switch according to claim 3 and further including a third wire connecting to a third contact, said third contact mounted upon the surface of said support frame adjacent and electrically isolated from said first contact whereby said movement of the portion of the persons skin by the person causes the leverarm to contact third contact or said first contact.

Claim 6

An electrical switch operable by movement on a first portion of a persons body relative to a second portion, said switch including two wires for switchable connection and comprising: a band mounted upon said second portion and including a nonconducting frame with a first electrical contact extending from one point on said frame to a second point on said frame forming a loop extending from said frame and having said first wire connected to said first contact; and an electrically conducting support bracket pivotally mounted upon said frame encompassing said first contact, said bracket extending from said frame and including a friction wheel rotationally mounted on the bracket, said wheel including an electrically conductive leverarm located on the perimeter of the wheel and extending through the wheel making electrical contact with said bracket and having an opposite leverarm end extending within said loop formed by said first contact, said wheel located to rest against said first body portion and rotatable upon movement of said first body portion causing said leverarm to make and break contact with said first contact.

Claim 7

An electrical switch operable by movement on a first portion of a persons body relative to a second portion, said switch including two wires for switchable connection and comprising: a band mounted upon said second portion and including a nonconducting frame with a first electrical contact extending from one point on said frame to a second point on said frame forming a loop extending from said frame and having said first wire connected to said first contact; and an electrically conducting support bracket pivotally mounted upon said frame encompassing said first contact, said bracket extending from said frame and including a friction wheel rotationally mounted on the bracket, said wheel including an electrically conductive leverarm located on the perimeter of the wheel and extending through the wheel making electrical contact with said bracket and having an opposite leverarm end extending within said loop formed by said first contact, said wheel located to rest against said first body portion and rotatable upon movement of said first body portion causing said leverarm to make and break contact with said first contact.

Claim 8

An electrical switch according to claim 5 further including a third wire connected to an electrically conductive rail mounted upon said frame adjacent to but electrically isolated from said first contact wherein movement of said first body portion causes said leverarm to contact said rail or said first contact.
