PROBLEM TO BE SOLVED: To provide a switch device that can stabilize the contact when the switch is turned on while reducing variations in the turn-on positions and is made thin by using less components. SOLUTION: This switch device has a torsion coil spring 6 to give return resilience to the operation lever 5. This torsion coil spring 6 has a coil 6a and a first and a second free arms 6b, 6c extending in one direction with a predetermined open angleβfrom both ends of the coil. The first arm 6b is always in elastic contact with a fixed contact 2, and the second arm 6c elastically contacts the surface 5g of an operation lever 5. A switching contact 3 is made in a clip shape and has a pair of contacts 3g, 3h. The second arm 6c contacts the contacts 3g, 3h and can slide while being elastically sandwiched by them when the operation lever is turned. COPYRIGHT: (C)2004,JPO |
