A non-conductive housing retains a small battery slidably within a recess in the housing. An electrically conductive clip or plate holds the battery within the recess. In an "off" position the battery contacts the non-conductive housing. Moved to the "on" position the battery contacts a thin conductive layer bonded to the housing, thereby completing and adding power to a circuit connected with the clip and an electrical or electronic element or device to be powered. Lighted or sounding jewelry or other small items containing an electrical element are applications. Additional positions of the movable power source may control other circuits causing other electrical and electronic effects such as flashing or sequential lights.
