In addition, in the present embodiment, the conductive part 16 as the circular cross-section of armature contact is shown.
As shown in the figure, the fixed contact 19 of this switch element 13 is formed by common contact portion 21, the 1st contact portion 22 and the 2nd contact portion 23, and this common contact portion 21 forms pattern on tellite 18.
That is, common contact portion 21 is formed as band pattern 21a ~ 21f, this band pattern 21a ~ 21f using the conductive part 16 as armature contact in the face of region pars intermedia Q centered by, extend radially according to 60 degree of intervals.
Further, the 1st contact portion 22 and the 2nd contact portion 23 clamp specific band pattern 21a, the 21d (being called below " 21ad ") in common contact portion 21 and form the pattern of semicircle shape.
Specifically, 1st contact portion 22 is formed by the 1st contacts patterns 22a, 22b and the 1st separated contacts pattern 22c, 1st contacts patterns 22a, 22b are in the side of specific band pattern 21ad, formed between band pattern 21a and 21b and between band pattern 21c and 21d, 1st separated contacts pattern 22c, at the opposite side of specific band pattern 21ad, is formed between band pattern 21e and 21f.

In addition, 2nd contact portion 23 is formed by the 2nd contacts patterns 23a, 23b and the 2nd separated contacts pattern 23c, 2nd contacts patterns 23a, 23b are at the opposite side of specific band pattern 21ad, formed between band pattern 21d and 21e and between band pattern 21f and 21a, 2nd separated contacts pattern 23c, in the side of specific band pattern 21ad, is formed between band pattern 21b and 21c.
In addition, the 2nd contacts patterns 23a, 23b and the 2nd separated contacts pattern 23c form planar contact, and this planar contact arranges narrow interval between each band pattern, and extends towards pars intermedia Q.
Further, the 1st contacts patterns 22b of above-mentioned 1st contact portion 22 and the 1st separated contacts pattern 22c by through-hole section 24a, 24b and be arranged at tellite 18 inner face electrical connection pattern 25 and be electrically connected.
Similarly, the 2nd contacts patterns 23b of above-mentioned 2nd contact portion 23 and the 2nd separated contacts pattern 23c by through-hole section 26a, 26b and be arranged at tellite 18 inner face electrical connection pattern 27 and be electrically connected.
Further, label 21p, 22p, 23p shown in Fig. 2 represent the projecting terminal portion of each contact portion.
The occasion that the fixed contact 19 formed as above contacts at the conductive part 16 as armature contact, be made up of switch element 28a ~ 28l, this switch element 28a ~ 28l is formed at the 1st, the 2nd contacts patterns 22a, between 22b, 23a, 23b and band pattern 21a ~ 21f and between the 1st, the 2nd separated contacts pattern 22c, 23c and band pattern 21a ~ 21f.
That is, as shown in Figure 3, the multiconductor part of the switch element represented by label 28a ~ 28l forms switch sections.In addition, in the present embodiment, 28a, 28b, 28e, 28f, 28i, 28j in this switch element 28a ~ 28l form switching circuit SW1 ((SW1-l) ~ (SW1-3)), switch element 28c, 28d, 28g, 28h, 28k, 28l form switching circuit SW2 ((SW2-l) ~ (SW2-3)), switching circuit SW1 and SW2 all connects, thus, switch element 13 is in on-state.
In addition, be also same for switch element 14.
In the fixed contact 19 formed as described above, if the overall even contact of the contact-making surface of conductive part 16, then whole switch element contact of 28a ~ 28l, two switching circuits SW1, SW2 connect at once, but in the occasion of conductive part 16 inclination contact, there is at the contact initial stage situation of two switching circuit SW1 and SW2 access failure, after contact can demand working.
Such as, give one example, then have following such situation, that is, at the contact initial stage, contact with the 1st contacts patterns 22a, then, after contacting with band pattern 21a and/or 21b, contact with the 2nd contacts patterns 23b or the 2nd separated contacts pattern 23c.
That is, due to conductive part 16 inclination contact, therefore first contact with the 1st contacts patterns 22a, during the connection after conductive part 16 is carried out, switch element 28a and/or 28b connects, and thus, switching circuit SW1 connects, then, switch element 28l and/or 28c connects, and thus, switching circuit SW2 connects.
Therefore, in the operation etc. of the state tilted by operating knob, the occasion that conductive part 16 tilts slightly and contacts with fixed contact 19, as mentioned above, switch element 13 is at the contact initial stage, two switching circuits SW1, SW2 all disconnect, but, delayed when slightly little, two switching circuits SW1, SW2 all connect, but due to as switch element 28a ~ 28l, form multiple fixed contact 19, therefore switch element 13 was connected with the few time difference after the contact of conductive part 16.
Give one example, after not only contacting from conductive part 16 with the 1st contacts patterns 22a until time difference contact with band pattern 21a and/or 21b seldom, and to touch the time difference contacted with the 2nd contacts patterns 23b or the 2nd separated contacts pattern 23c also few with the 1st contacts patterns 22a.
The contact position at the initial stage of conductive part 16 be other contacts patterns, separated contacts pattern, band pattern occasion, this relation is also identical.
Fig. 4 represents relative fixed contact 19, and conductive part 16 relatively pars intermedia Q misplaces and the state of contact.
In the present embodiment, form following switch element 13, wherein, because the 1st contacts patterns 22a, 22b, the 1st separated contacts pattern 22c and the 2nd contacts patterns 23a, 23b, the 2nd separated contacts pattern 23c are formed as the planar contact extended towards pars intermedia Q, even if therefore when the relative pars intermedia Q of conductive part 16 misplaces and contacts, two switching circuits SW1, SW2 still positively connect.
In addition, form following switch element 13, wherein, even if when conductive part 16 tilts and misplaces and contact, also same as described above, in the short time of conductive part 16 after contacting with a contact portion (such as the 1st contact portion 22), contact with another contact portion (such as the 2nd contact portion 23), this switch element 13 is connected.
Above switch element 13 is illustrated, but due to as described, switch element 14 is same structure, therefore omits as the conductive part 17 of armature contact and the explanation of fixed contact 20.
Fig. 5 represents the figure with the circuit example of the engine start switch 10 of above-mentioned switch element 13,14.

The invention is characterized in and the 1st contacts patterns 22a, 22b and the 2nd separated contacts pattern 23c and the 2nd separated contacts pattern 23a, 23b and the 1st separated contacts pattern 23c are alternately arranged between band pattern 21a ~ 21f.
Namely, switching circuit SW1 ((SW1-1), (SW1-2), (SW1-3)), SW2 ((SW2-1), (SW2-2), (SW2-3)) are from band pattern 21a in the counterclockwise direction, arrange according to the order of (SW1-1) → (SW2-3) → (SW1-2) → (SW2-1) → (SW1-3) → (SW2-2), often according to clamping band pattern 21a ~ 21f, adjacent mode is arranged switching circuit SW1 and SW2.
By this setting, the distance between point that switching circuit SW1 contacts with band pattern 21a ~ 21f and the point that switching circuit SW2 contacts with band pattern 21a ~ 21f can be reduced, and often form certain distance.
So, even if owing to tilting at the relative switch element 28a ~ 28l of conductive part 16 when contact, the time difference in the moment that switching circuit SW1 connects and the moment that switching circuit SW2 connects is little, and be often certain, do not produce deviation, therefore the connection that vehicle side control device 29 positively carries out switching device judges, the reason of the deviation in the moment because of signal input can be reduced and be judged to be wrong possibility.
Due to the engine start switch 10 that forms as such under common state as shown in Figure 1, by the push operation of operating knob 11, elastic portion 15a, 15b is promoted by its pushing part 11c, 11d, the conductive part 16,17 of pretending as armature contact contacts with fixed contact, and the switch element 28a ~ 28l of switch element 13,14 connects simultaneously.
Therefore, this connection signal is delivered to the control device 29 of vehicle side, thus carries out the startup of engine or the stopping of engine.
In addition, because of machinery travelling of operating knob 11 and keeper 12, rocking of long-term use and the machinery of the operating knob 11 caused, in order to carry out push operation to operating knob 11 in an inclined manner, even if connect when the switching circuit SW1 of switch element 13 is different with switching circuit SW2, a relative switching circuit, when another switching circuit time of origin postpones and connects, owing to connecting in the short time after the contact of conductive part 16, therefore these two switching circuit SW1, the time lag that SW2 connects is minimum, can judge that the control device 29 inputting these connection signals is connected substantially simultaneously, correctly ato unit or stopping engine.
Consequently, the switching device with switch element 13,14 of present embodiment forms engine start switch as vehicle and effective switching device.
