PROBLEM TO BE SOLVED: To provide an operation strip operating mechanism and a switch device with the same capable of widening an operating angle position with a notch feeling obtained up to a nearby position of an operating angle of an operating strip. SOLUTION: The mechanism includes an operating shaft 6 linked with operation of an operating handle 5, a first cam member 7, a second cam member 8, a third cam member 9, a spring 10 biasing the second cam member 8 toward a third cam 9 side, a regulating means for regulating rotation of the second cam member 8, or the like. A top face of the first cam member 7 constitutes a first cam face 7A, a lower face of the second cam member 8, a second cam face 8A, a top face of the third cam member 9, a third cam face 9A engageable with the second cam face 8A, and a lower face of the third cam member 9 constitutes a fourth cam face 9B engageable with the first cam face 7A. Provided, a sloped angle of one of the slopes of a cam nose of the third cam face 9A is θ1, that of the other slope is θ2, a sloped angle of one of the slopes of a cam nose of the fourth cam face 9B is θ3, and that of the other slope is θ4, formulae of: θ2>θ3, and θ4>θ1 are satisfied.

PROBLEM TO BE SOLVED: To provide an ignition switch easy in assembling work and reducible in the number of parts. SOLUTION: An ignition switch 10 comprise a terminal base 30 in which at least two fixed contacts 34 and 36 are provided, a movable bridge contact 48 to which the two fixed contacts 34 and 36 are electrically connected, a spring 66 for energizing the movable bridge contact 48 to the fixed contact 36 side, and a push pin 52 that is movably mounted in a holding hole 50 formed in a terminal base 30 so as to make its one end push the movable bridge contact 48 to an opening direction. A case 60 in which the movable bridge 48, the spring 66 and the push pin 52 are housed in a housing 31 of the terminal base 30 so as to be undetachable is fixed in the terminal base 30, and the push pin 52 is operated by making its other end protruded from the outer surface of the terminal base 30 abut against a cam 26 of a rotor 16.

Abstract:
PROBLEM TO BE SOLVED: To provide a rotary switch device having a high reliability about its switching accuracy without working upon it actually and considerably. SOLUTION: The rotary switch device has a knob 12 with wave shape guide portion 18 which is disposed at a rotating direction of the knob 12. Contact holders 19 and 20 are disposed at the wave shape guide portion 18 in such a way that they are moved in linear reciprocating directions respectively together with movable contacts 23 and 24 following the rotation of the knob 12 by projections 21 and 22. A distinct state of connection of the movable contacts 23 and 24 to fixed contacts 26, 27 and 28 is realized successively by respective linear reciprocating motions of the plurality of contact holders 19 and 20 following the rotation of the knob 12.

Abstract:
PROBLEM TO BE SOLVED: To provide an automatic neutral point return type shuttle switch mechanism having a switch structure and operating principle allowing a switch-on to effectively make an operator recognized visually and by a variation in rotating resistance of a shuttle switch, manufactured at a low cost, and providing a high durability. SOLUTION: This shuttle switch mechanism comprises a rotating body 20 having, on the peripheral surface thereof, a projected plate with a flat rear surface and a flat projected part formed at the center part on the rear surface and a lateral rotation stopper 33 coming into contact with one end part of the projected plate in rotating direction and determining the maximum rotating position of the rotating body. The upper end of a bar body 50 is pushed down while being arrested by the projected part of the projected plate, and the lower end of the bar body 50 is also pushed down to turn on the switch. In addition, when the rotating body 20 is returned by rotation, the upper end of the bar body is pushed down while being arrested by the rear surface of the projected plate, and the lower end of the bar body is also pushed up to turn off the switch.
