Next, the slider 1 and the action pin 1
The case where the first stroke is changed, that is, the case where the full stroke and the lock stroke are changed will be described. FIG.
Suppose that the full stroke is 5 mm and the lock stroke is 3 mm as shown in FIG. In this case, the action pin 11 moves as shown in FIG. That is, in the initial position, it is in the state shown by the solid line in the figure, at the full stroke position it is at the position shown by the dashed line in the figure, and at the lock stroke position it is at the position shown by the broken line in the figure. The distance between the end surface 2 of the slider 1 and the inner end surface 52 of the terminal member 51 is 5 mm corresponding to the full stroke. In FIG. 5, the action pin 11 is indicated by a solid line.

Next, from the above state, the full stroke is 3
mm and lock stroke to 1.5 mm.
In that case, first, extend the tip of slider 1
The distance between the end face 2 and the inner end face 52 is 3 mm. At the same time, the mounting position of the action pin 11 with respect to the slider 1 is moved to the right side in the figure by a predetermined amount (1.5 mm).
At that time, the attachment position of the action spring member 13 also moves at the same time. Thereby, the action pin 11
Moves in a state as shown in FIG. 7 with the movement of the slider 1, and the full stroke is 3 mm and the lock stroke is 1.5 mm. At the initial position, it is in the state shown by the solid line in the figure, at the full stroke position at the position shown by the dashed line in the figure, and at the lock stroke position it is at the position shown by the broken line in the figure. In FIG. 5, the action pin 11 is indicated by a broken line.

That is, when changing the full stroke and the lock stroke, the distance between the end surface 4 of the slider 1 and the inner end surface 52 of the terminal member 51 is changed as appropriate, and the action pin 11 and the action spring member 13 are changed.
May be appropriately changed with respect to the slider 1. To change the attachment position of the action pin 11 and the action spring member 13 with respect to the slider 1, the opening 7, the hole 9, the openings 15, 17, and the opening 2
5 will be changed. In any case, when changing the full stroke and the lock stroke, only the slider 1 which is a plate-shaped member needs to be changed.

Incidentally, as the circuit configuration of the switch device according to the present embodiment, for example, those shown in FIGS. 8 to 13 can be considered. 8 and 9 show the first type,
FIGS. 10 and 11 show the second type, FIGS. 12 and 1
FIG. 3 shows a circuit configuration of a third type of switch device. In any case, the lamp 81 is turned on when the switch is turned on (that is, the contact member 23 and the terminal 49 are electrically connected).

According to this embodiment, the following effects can be obtained. First, since the standardization of each component of the switch device has been promoted, it is possible to easily cope with a change in specifications, specifically, a change in full stroke and lock stroke. That is, in the conventional case, the entire slider 101 having the cam portion 103 has to be changed, whereas in the case of the present embodiment, only the slider 1 needs to be changed. Comparing the change of the slider 101 with the change of the slider 1, the former requires complicated work and high cost, such as a need for a large change of the mold. Since it is manufactured by press molding, the operation is simple and the cost is low. All parts other than the slider 1 can be used as common parts. Also, when it is desired to change the shape of the cam portion 45 due to a large specification change, only the cam member 41 needs to be changed.

Each component can be assembled and functioned without covering the cover 75. So, for example,
The performance test and the like can also be performed without covering the cover 75. Even if there is a defective part to replace it, it is convenient because the cover 75 is not covered.

As another effect, the spring member 13 is provided.
Since the contact member 23 is integrally provided, the number of components can be reduced as compared with the case where the components are separately provided in the related art, and assembling work is facilitated and component management is also simplified. Further, the terminal 49 is fixed to the substrate 37 by simple fitting, so that the soldering work and the caulking work as in the related art can be made unnecessary. Can be simplified.

The present invention is not limited to the above embodiment. For example, in the case of the above-described embodiment, a type is described in which the initial position is the full stroke, the full stroke is the lock stroke, the lock stroke is the full stroke, and the full stroke is the initial position. The present invention can be applied to a device having a stroke position.

[0034]

As described in detail above, according to the switch device of the present invention, standardization of each part is promoted, so that specification changes can be easily dealt with by changing minimum members. It became so. Also, since all parts can be assembled in a predetermined state without covering the cover, it is possible to perform performance tests without covering the cover. became.
