PROBLEM TO BE SOLVED: To provide a ring-shaped switch which is produced with high precision, wired without blind sections and variable in length. SOLUTION: The ring-shaped switch of this invention comprises an inner ring and an outer ring connected by two rising edges opposed each other and a length is provided by these rings. Conductive rubbers opposed each other are fit on these inner and outer rings across a space so that they are pressed and brought into contact with each other to conduct electricity and electrode core wires are prepared on respective conductive rubbers along the rising edges. A stand is inserted into an opening of the ring-shaped switch between the rising edges so that the leg of the stand is easily attached to a mounting to wire the switch. COPYRIGHT: (C)2005,JPO&NCIPI
