JPH1125799A - Lever tip switch - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a lever tip switch with which a sense can be grasped easily as when a switch is turned on while plural switches can be provided at the same time. SOLUTION: This switch is structured by placing a push-button switch 11 at the tip of a lever 1. In this case, a wiring base plate 12 with a fixed contact 12a is provided in the lever 1, and a rubber contact 13, which is structured for separating a movable contact 13a from the fixed contact 12a for a specific distance by a rubber part 131 formed into a skirt shape, is provided on the wiring base plate 12. The movable contact 13a is then made so as to abut the fixed contact 12a, by pushing the rubber contact 13 via the push-button switch 11.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lever end switch in which, for example, in a steering column of an automobile, a push button is arranged at the end of a lever projecting sideways.

[0002]

2. Description of the Related Art As this kind of lever end switch,
For example, the one shown in FIG. 2 is known. That is, the head of the push button 2 is exposed at the tip of the lever 1, and a coil spring 3 that constantly urges the push button 2 outward is provided inside the push button 2. One end of the coil spring 3 comes into contact with the inner surface of the head of the push button 2 and
The end is a movable contact 3a. The other end of the push button 2 is in contact with the conductive plate 4. A lead wire 5 is connected to the conductive plate 4.

A pipe 6 is provided at the center of the lever 1 and a fixed contact 7
Is attached. This fixed contact 7 has a lead wire 8
Is connected.

In the lever end switch configured as described above, when the push button 2 is pressed downward, the movable contact 3a comes into contact with the fixed contact 7, and the lead wire 5 and the lead wire 8 are brought into conduction.

[0005]

However, in the above-mentioned conventional lever end switch, there is a disadvantage that only one switch can be provided for one lever 1 because the number of parts is large and the structure is complicated due to its structure. is there. Further, since the user feels that the switch has been turned on by an increase in the force when the movable contact 3a hits the fixed contact 7, there is a problem that it is difficult to sense when the switch is turned on.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is to provide a plurality of switches and a lever-end switch capable of easily grasping a feeling when the switches are turned on. Is to provide.

[0007]

In order to achieve the above object, the present invention is directed to a lever end switch in which a push button is arranged at the end of a lever, wherein a wiring having a fixed contact is provided in the lever. A substrate is provided, and a rubber contact formed so as to separate a movable contact from a fixed contact by a predetermined amount by a rubber portion formed in a skirt shape is provided on the wiring substrate, and the rubber contact is provided via the push button. By pressing the movable contact, the movable contact is configured to contact the fixed contact.

In the invention configured as described above, the rubber contact has a spring function and a movable contact, and the wiring board has a fixed contact. The number of parts for forming one switch is reduced, and the structure is extremely simplified. Therefore, two or more switches can be provided at the tip of one lever.

Further, when the rubber contact is pushed,
The skirt-shaped rubber portion buckles, and the elastic force for holding the movable contact sharply decreases, so that the movable contact comes into contact with the fixed contact. Therefore, the feeling when the switch is turned on can be easily grasped.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG. In this figure, reference numeral 1 denotes a lever which projects laterally in a steering column of an automobile, and two push buttons 11 are provided at the tip of the lever 1 with their heads exposed.
Each push button 11 is allowed to move inward of the lever 1, but is prohibited from being pulled out of the lever 1 by the claw 11 a.

A wiring board 12 having a fixed contact 12a is provided in the lever 1. On the wiring board 12, a movable contact 13a is separated from the fixed contact 12a by a predetermined amount by a rubber portion 131 formed in a skirt shape. The rubber contacts 13 are provided so as to be separated from each other.
By pressing, each movable contact 13a is connected to each fixed contact 12
a.

That is, each rubber contact 13 has a skirt-shaped rubber portion 131 on the outer periphery of the columnar portion 130, and the base of the rubber portion 131 is fixed to the wiring board 12. Then, the upper surface of the cylindrical portion 130 is in contact with the bottom surface of the push button 11, and the elastic force of the rubber portion 131 pushes up the push button 11. Also,
A movable contact 13a is fixed to the bottom surface of the cylindrical portion 130 so as to face the fixed contact 12a.

In the lever end switch constructed as described above, the movable contact 13a comes into contact with the fixed contact 12a by pressing each push button 11 downward, and the circuit of the wiring board 12 is turned on. Can be.

The rubber contact 13 has a function of a spring and a movable contact 13a.
Since the wiring board 12 includes the fixed contacts 12a, the number of components for forming one switch is small and the structure is extremely simple. Therefore, two switches can be provided at the tip of the lever 1.

When the rubber contact 13 is pushed by the push button 11, the skirt-shaped rubber portion 131 buckles, and the force for elastically holding the movable contact 13a sharply decreases, and the movable contact 13a becomes fixed. 12a. Therefore, the feeling when the switch is turned on can be clearly grasped. For this reason,
Since it is not necessary to press the push button 11 with excessive force, the switch operation during driving becomes easy and traffic safety can be improved.

In the above embodiment, two switches are provided at the tip of the lever 1. However, three or more switches may be provided.
For example, in FIG.
It is easy to provide one or two switches.

[0017]

According to the present invention, the rubber contact has a function of a spring and a movable contact, and the wiring board has a fixed contact. And the structure becomes extremely simple. Therefore, 1
Two or more switches can be provided at the tip of one lever.

When the rubber contact is pushed,
The skirt-shaped rubber portion buckles, and the elastic force for holding the movable contact sharply decreases, so that the movable contact comes into contact with the fixed contact. Therefore, the feeling when the switch is turned on can be easily grasped.
