DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a switch for changing a switching mode according to an operation of an operating member from a non-operating position, for example, a stop switch and a cruise switch for changing a switching mode according to a brake operation of a brake pedal. And a jig for determining a mounting position of the switch on the support when screwing the switch to the fixed support.

[0002]

2. Description of the Related Art Since the distance between an operating member in a non-operating position and a fixed support is not fixed due to an assembling error or the like, the position of the switch case with respect to the support in the forward and backward directions of the switch case is determined. If it is fixed, the operating position of the operating member for which the switch changes the switching mode is not fixed. Thus, the switch case is screwed into the support member by a predetermined angle from the time when the switch changes the switching mode by screwing the switch case into the support so that the detector is pressed against the operating member that is stationary at the inoperative position. If the switch is mounted on the support so that the switch is further rotated in the direction, the switch changes the switching mode in response to the operation member being operated by a predetermined amount from the non-operation position. Therefore, conventionally, after confirming that the switching mode of the switch has changed due to the screwing of the switch case into the support, the switch case is further screwed in with the guide of the operator.

[0003]

However, if the mounting position of the switch to the support is determined by the operator as in the prior art, the mounting position varies greatly,
Depending on the proficiency of the operator, malfunction may occur in a device that uses a signal change accompanying a change in the switching mode of the switch as an operation switching timing.

The present invention has been made in view of such circumstances, and it is an object of the present invention to provide a switch mounting position confirmation jig which can easily and accurately determine a switch mounting position regardless of an operator. Aim.

[0005]

In order to achieve the above-mentioned object, the invention according to the first aspect of the present invention is directed to a fixed support which is opposed to an operating member which is biased by a first spring toward a non-operating position. A switch case that is screwably mounted, a detector that is supported on the switch case so as to be movable in the forward and backward directions of the switch case, and that the detector projects from the switch case with a smaller spring load than the first spring. A second spring that biases the spring in the direction in which the switching element is switched in accordance with the movement of the detector.
When the detector is brought into contact with the operating member from the non-operating position side and attached to the support, the switching mode of the switch is changed so as to change a switching mode according to the operation member operating a predetermined amount from the non-operating position. A jig main body attached to the switch so that relative rotation of the switch case around a screwing axis is disabled, and a jig main body incorporated in the jig main body. A battery that is connected to the switch and the battery so as to switch power supply / interruption from the battery in accordance with a change in the switching mode of the switch, and a confirmation light attached to the jig body. The reference ring, which is rotatably mounted on the jig main body so that the user can grasp and fix the When the switch case is further screwed into the support after the switch case is screwed into the support body, the relative rotation amount of the jig main body with respect to the reference ring fixed and grasped by an operator is a predetermined value. A relative angle checking means is provided between the jig main body and the reference ring so that the jig can be checked.

According to the first aspect of the present invention, when the switch case of the switch on which the jig body is mounted is screwed into the support, the first spring is biased toward the inoperative position by the first spring. The outer end of the detector, which is biased by a second spring having a smaller spring load than the first spring and protrudes from the switch case in a direction protruding from the switch case, comes into contact with the operating member from the inoperative position side. The second spring is pushed into the switch case while compressing it. As a result, the switch changes the switching mode, and the power supply to the confirmation light by the dry battery is switched or cut off in accordance with the switching of the switching mode. Therefore, the operator confirms that the switching mode of the switch has changed. Can be checked by turning on or off. When the mounting position of the switch to the support is determined in this state, the switch immediately changes the switching mode in response to the operation of the operating member from the non-operation position. In order to change the switching mode of the switch accordingly, the switch case may be further screwed into the support by the amount of movement of the detector according to the predetermined amount of operation of the operating member. Thus, the rotation amount of the switch case corresponding to the further screwing amount of the switch case is set in advance, and after checking whether the confirmation light is turned on or off, the operator holds the reference ring and fixes the reference ring. so,
When the switch case is further screwed in, the relative rotation amount of the jig body with respect to the reference ring, that is, the preset rotation operation amount of the switch case is confirmed by the relative angle checking means provided between the jig body and the reference ring. can do. Therefore, the mounting position of the switch on the support can be easily and accurately determined regardless of the skill level of the operator.

[0007] The invention according to claim 2 provides the above-described claim 1.
In addition to the configuration of the invention described above, the relative angle confirmation unit includes:
A reference mark displayed at one location along the circumferential direction of the reference ring, an alignment mark displayed at one location in the circumferential direction of the jig main body, and a projection provided at one location in the circumferential direction of the jig main body; A recess provided in the reference ring so that the protrusion is inserted, and the recess is provided with a jig in a state in which the protrusion comes into contact with one circumferential end when the alignment mark is aligned with the reference mark. The projection is provided on the reference ring within an angular range in which the main body is relatively rotated with respect to the reference ring by a predetermined rotation amount so that the protrusion contacts the other end in the circumferential direction.

[0010] According to the configuration of the second aspect of the present invention, after confirming whether the confirmation lamp is turned on or off, the operator adjusts the reference mark to the alignment mark of the jig main body so that the operator can attach the reference ring. By screwing the switch case in a state of being gripped and fixed, the protrusion comes into contact with the other end in the circumferential direction of the concave portion, so that the relative rotation amount of the jig main body with respect to the reference ring can be easily confirmed.

According to a third aspect of the present invention, in addition to the configuration of the first aspect, the relative angle confirming means includes a reference mark displayed at one position along a circumferential direction of the reference ring, The alignment mark displayed at one location in the circumferential direction of the fixture main body and the alignment mark indicate that the jig main body has relatively rotated by a preset amount of rotation with respect to the reference ring from a state where the alignment mark is aligned with the reference mark. And a scale displayed on the reference ring so that it can be confirmed by comparison with the reference ring.

[0010] According to the configuration of the third aspect of the present invention, after confirming whether the confirmation lamp is turned on or off, the operator sets the reference ring to the alignment mark of the jig main body so that the operator can attach the reference ring. When the switch case is screwed in while being gripped and fixed, the relative rotation amount of the jig main body with respect to the reference ring can be easily confirmed by comparing the alignment mark with the scale.
