Description

DETAILED DESCRIPTION OF THE INVENTION The present invention enables the contact holder to slide into several positions within the switch case, and to select from several swing angles in the right angle direction at each sliding position. The compound switch is configured to control the on/off operation of a type of switch, and the contact holder is provided with an insulator that faces a side surface in a sliding direction of the contact holder, and the contact holder includes:
A plurality of contact insertion holes arranged in the swinging direction are provided on the surface corresponding to the insulator, and a plurality of movable contacts with different lengths protruding in the sliding direction can be inserted into each contact insertion hole by a spring. A plurality of contact plates corresponding to the movable contacts are fixed to the insulator at each swing position of the contact holder, and a combination of sliding and swinging of the contact holder causes the plurality of movable contacts to be fixed to the insulator. It is characterized in that one of the plurality of contact pieces is brought into contact with and separated from one of the plurality of contact pieces, and in particular, when a large number of switches are installed, and in many cases, it is used for opening, closing, switching, etc. of multiple circuits of the same system. It is an object of the present invention to provide a composite switch suitable for installation in vehicles in which control is often performed by moving a single contact holder while preventing erroneous operations as much as possible.

Various types of combination switches for vehicles are known in which a contact holder is slid into several positions and is configured to swing through several swing angles at each sliding position. However, the contact holder and the insulator to which the contact plate is attached are arranged to face the sides of the contact holder in the sliding direction, or the movable contacts are made to protrude from the contact holder toward the contact plate on the insulator. There is no structure in which the number of movable contacts that contact the insulator is sequentially changed depending on the sliding position of the movable contacts, and the present invention is characterized in that it includes such a structure.

An embodiment of the invention will be described with reference to the accompanying drawings.

The contact holder 14 is further set with a third swing angle, but from this swing angle it immediately returns to the second swing angle. By fitting the spring 22 and a part of the engaging element 23 between the two and applying the left end of the engaging element 23 to the upright part 3, when the contact holder 14 swings to the third swing angle, the spring 22 is compressed, the contact holder 14 operates to return to the second swing angle due to the return force of the spring 22.

This embodiment is a light switch for automobiles (many small groups of lights such as exterior side lights, number lights, instrument lights, etc., and a two-stage opening/closing action that opens and closes the circuit between these small light groups and headlights. ), a daymer switch, and a passing switch.The contact plate 51 is used as the power source B, and the contact plate 52 is used as the power source B.
to the main headlight HU, and the contact plate 53 to the small light group S.
Then, the contact plate 54 is connected to the main headlamp HU, and the contact plate 55 is connected to the auxiliary headlamp HL.

The operation of the composite switch of this embodiment will be explained as follows.

[1] When the contact holder 14 is moved to the first sliding position a by the operating knob 21 and the engagement ball 19 is engaged with the ring groove 9, the contact 35 is moved at the first and second swing angles. is in contact with the contact plate 51, but the contact 37 is in contact with the contact plate 54, 55.
(Figs. 3 and 4), and the contact 31 does not contact the contact plates 51, 53, so all the compound switches are "off" in this state (in broad daylight).

[1a] When the contact holder 14 is swung to the third swiveling angle by the operating knob 21 at the first sliding position a, the contacts 35 move toward the contact plates 51, 5.
2 and turn on the main headlight HU. However, at that time, the spring 22 is compressed and at the same time the engagement ball 20 rides on the arcuate concave surface 2, so as soon as you release the operating knob 21, the part automatically returns to the second swing angle and turns off the main headlight. Produces a sing switch effect.

[2] Move the contact holder 14 to the second sliding position b using the operating knob 21 and insert it into the engagement ring groove 10.
When the engagement ball 19 is engaged with the contact plate 5, the contact 31 is moved to the contact plate 5 at the first and second swing angles.
1 and 53, the small lamp group S is turned on. However, since the holder 14 is normally at the first and second swing angles, the main headlight HU is not turned on by the contact 35 (at dusk). The above operation produces the first stage action of the light switch.

[2a] Contact holder 14 in the state of [2]
When oscillated to the third oscillation angle, the above [1a]
Accordingly, a passing switch is activated to turn on the main headlights HU, and at this time, the small light group S also remains lit by the contacts 31.

[3] Use the operating knob 21 to move the contact holder 14 to the third sliding position c and engage the ring groove 11.
When the engagement ball 19 is engaged with the contact 31, the contact 31 remains in contact with the contact plates 51 and 53 as in [2], and the small light group S continues to be lit. Therefore, at the first swing angle, the contact 35 contacts the contact plate 51, and the contact 37
contacts the contact plate 54, and the power supply current is applied to the movable plate 3.
9, the signal flows from contact 35 to contact 37, so that the main headlight HU is turned on. Further, when the contact holder 14 is swung to the second swiveling angle, the contact of the contacts 31 with the contact plates 51 and 53 does not change, and the contact of the contacts 35 with the contact plate 51 also does not change.
The small lamp group S and the auxiliary headlamp HL are turned on (at night) because they touch the contact plate 55 away from the lamp. That is, the above-mentioned operation produces the action of the second stage of the light switch and the action of the dimmer switch which switches on the main and sub-headlights HU and HL.

[3a] When the contact holder 14 is swung to the third swiveling angle using the operation knob 21 in the state of [3], the contact between the contacts 31 and 37 does not change, but the contact 35 comes into contact with the contact plates 51 and 52, This produces a passing switch effect that turns on the main headlight HU while leaving the small lamp group S and the auxiliary headlight HL on.

The compound switch shown in the above embodiment is installed close to one grip of the handlebar of a two-wheeled vehicle, with the operating knob 21 of the contact holder facing the driver as shown in FIG. , select the above-mentioned sliding motion and rocking motion, and perform a switch operation.

As clarified by the explanation of the above embodiments, the compound switch of the present invention slides the contact holder to several positions a to c within the switch case, and at each position further moves the contact holder to several positions perpendicular to the sliding direction. By arbitrarily selecting the sliding position and swing angle of the contact holder, the contact holder protrudes toward the insulator corresponding to the side surface in the sliding direction of the contact holder. It controls the contact/separation operation between a plurality of movable contacts in a contact holder and a plurality of contact plates embedded in the surface of an insulator, that is, the on/off operation of a plurality of switches, and its configuration is as follows: It is unique compared to previous combination switches for vehicles, and has superior operability.
It has the advantage of increasing the number of multiple switches, selection operations, and operations.
