Embodiment
At first seeing also Fig. 1～Fig. 3, is the fixed structure of a kind of rotary switc provided by the utility model, and it mainly is made up of a pedestal 11, a knob 21 and a loam cake 31, wherein:
This pedestal 11, its inside is formed with a room 12 that a upward opening arranged, and be provided with a circuit part 13 in these room 12 bottoms, and this circuit part 13 extends outwardly several can be for being plugged in pin 131 on the circuit board (not shown), and convex with a projection 14 on the two opposite side walls of this pedestal 11 respectively.
This knob 21 is axially to be installed in the room 12 of this pedestal 11, and this pedestal 11 carries out a spinning movement relatively, and is provided with a packing ring 22 between this knob 21 and this pedestal 11.These knob 21 tops are formed with an Actuator Division 23, and these knob 21 peripheries are to extend out to be formed with several and to be continuous jagged pushing part 24 along these knob 21 peripheries, and between each adjacent pushing part 24, define respectively and be formed with a location division 25, and be provided with a lead piece 26 in these knob 21 bottoms, this lead piece 26 is to rotate and to interconnect with circuit part 13 in this room 12 with this knob 21, so as to selecting conducting or cutting off local circuit, or the resistance value of change internal circuit, make this circuit part 13 can constitute several different circuit states.
This loam cake 31, its section generally is mouthful word and removes following one horizontal shape and have connecing and establish mouthfuls 32 down, this loam cake 31 is to connect with it to establish mouth 32 and corresponding being covered on the periphery of this pedestal 11, and in order to this knob 21 is located between this pedestal 11 and this loam cake 31, and be formed with a hook part 311 respectively in the position that 31 pairs of this loam cakes should pedestal 11 lateral walls two projections 14, and when these loam cake 31 correspondences are covered on this pedestal 11, this two hook part 311 is corresponding to collude on two projections 14 that are held in this pedestal 11, is integral so that this loam cake 31 must mutually combine with this pedestal 11.And these loam cake 31 end faces offer a through hole 33 that supplies these knob 21 tops to wear, and are provided with the sign portion 34 that is available for users to these knob 21 switching positions of identification in these loam cake 31 end faces.Offer a location hole 35 on these loam cake 31 1 sides, be horizontally set with this loam cake 31 internal recess and the flexible butted piece 36 of tool on one day in this location hole 35, can have supported relatively under the pressure of the curved arc section 361 in the location division 25 wherein and on the end face of this knob 21, be formed with one in this butted piece 36.
And the utility model of forming via said structure is when reality is used, as shown in Figure 4, as user and when rotating this knob 21 through the Actuator Division 23 of this knob 21, the pushing part 24 of this knob 21 gets final product the curved arc section 361 of this butted piece 36 of ejection, and when the power of rotating this knob 21 greater than this butted piece 36 provided shore elastic force the time, can make these butted piece 36 stressed extruding and be out of shape, and make the curved arc section 361 of this butted piece 36 can break away from clip state with this knob 21 location division 25a smoothly whereby; And, borrow the elastic force effect of this butted piece 36 itself when continuing this knob 21 of rotation, the curved arc section 361 of this butted piece 36 must be taken advantage of a situation under the pressure of next location division 25b in, and constitute once more and the state of these knob 21 mutual clips.Whereby, can make the utility model reach this knob 21 has certain location after rotation effect, and and then can effectively improve the shortcoming that knob 21 turned positions are certain inadequately and knob 21 is offset easily after rotating.
