In the rotary electric parts 100 of embodiment 1, accept rotary manipulation and pressing operation to operating axis 6 with this kind structure.When operating axis 6 is carried out pressing operation, overcome the acting force of force application component 4 and push pressing member 5 along axial (rear side of rotary electric parts 100) of operating axis 6.In this case, force application component 4 reverses under the effect of pushing of pressing member 5, and the movable tongue piece of the movable contact member 3 that is configured in its rear side is contacted with the central fixed contact of switch maintaining part 1c.Fig. 6 is the side cutaway view of the rotary electric parts 100 when operating axis 6 is carried out pressing operation.As shown in Figure 6, contact with the central fixed contact of switch maintaining part 1c, detect pressing operation and detection signal is carried out outside output by the movable tongue piece that makes movable contact member 3.
On the other hand, if operating axis 6 is rotated operation, then follow in this, engage with operating axis 6 and the rotary body 8 that keeps is rotated, the slide of fixing on its rear surface 9 rotates.In this case, slide 9 slides and rotation its sliding contact 9a, 9b respectively on switching pattern 7c, shared pattern 7d.Sliding contact 9a slides sliding on the conductive part 71a of the coding pattern 71 that constitutes switching pattern 7c, non-conductive the 71b and similarly constituting on conductive part 72a, non-conductive 72b of coding pattern 72 of switching pattern 7c.On the other hand, slide on sliding contact 9b conductive part 73a, non-conductive 73b in shared pattern 7d.That is, sliding contact 9a, 9b alternately slide on the conductive region that is made of sheet metal and the non-conductive zone that is made of insulative resin respectively.
So, in the rotary electric parts 100 of embodiment 1, owing on shared pattern 7d, be provided with non-conductive the 73b that constitutes by insulative resin, so the use-pattern that can avoid sliding contact 9b on the conductive region of shared pattern 7d, to slide all the time, thereby can reduce the wearing and tearing of the sliding contact part of sliding contact 9b and shared pattern 7d, realize the long lifetime of rotary electric parts.
In addition, in the rotary electric parts 100 of embodiment 1, the formation zone of non-conductive the 73b of shared pattern 7d forms the angle less than the formation zone of non-conductive 71b, the 72b of switching pattern 7c, and slide 9 constitutes, be positioned at the conductive part 71a (72a) of switching pattern 7c and the moment of the boundary portion of non-conductive 71b (72b) at the sliding contacting part of sliding contact 9a, the sliding contacting part of sliding contact 9b becomes the conductive part 73a state of contact with shared pattern 7d.Thus, can constitute the conducting region (conductive part 71a, 72a) that enters switching pattern 7c at sliding contact 9a makes sliding contact 9b enter the structure of the conducting region (conductive part 73a) of shared pattern 7d before.In this case, enter into the moment of the conducting region of switching pattern 7c at sliding contact 9a, sliding contact 9b has entered into the conducting region of shared pattern 7d, therefore can prevent when switching sliding contact 9a the situation that sliding contact 9b is switched with respect to the contact condition of the conductive part 73a among the shared pattern 7d, non-conductive 73b with respect to the contact condition of the conductive part 71a (72a) among the switching pattern 7c, non-conductive 71b (72b).Thus, can obtain stable pulse signal reliably.
