Abstract
A user operated switch has a support frame mounted to a person's body. A first electrical contact is mounted on and extends from the frame. Contacting structure includes a friction device positioned against a portion of the person's skin and is supported by an electrically conductive support arm. An electrically conducting lever arm has a first end mounted in the friction device in electrical contact with the support arm. A second end of the lever arm is located adjacent the first contact. Skin movement will cause contact between the first contact and the lever arm. The switch may be modified to act as a double throw, single pole switch.
