Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a multi-button switch such as an electric remote control mirror switch.

In electric remote control mirrors, it is necessary to incorporate a four-way switch in order to change the angle of the mirror vertically and horizontally, and when operating it, for example, when one push button is pressed, other push buttons It is necessary to control the position so that it does not move out of its predetermined position.

The present invention aims to provide a multi-button switch which has an extremely simple structure and is suitable as a switch for an electric remote control mirror as described above.

In order to achieve the above-mentioned objective, the present invention has a plurality of pushbuttons each having a contact point attached to the lower surface thereof, which are formed integrally with the movable piece through a thin hinge section on a concentric circle centered on the movable piece. ,
The movable piece is supported on a base on which a printed circuit board is layered via an elastic body and a protrusion, and the movable piece is covered with a cover fixed to the base, and the movable piece and the cover or the movable piece and the base side It is characterized in that a cross-shaped protrusion and a cross-shaped recess are provided between the protrusion and the two are engaged with each other.

Next, a specific example of the multi-button switch of the present invention will be explained with reference to the accompanying drawings.

1 to 4 show an embodiment of the present invention.

In these figures, 1 is a push button, and a movable piece 3
and are integrally molded via a thin-layer hinge portion 2, and each of the push buttons is arranged in four concentric circles with the movable piece 3 as the center.

Reference numeral 13 indicates a contact point attached to the lower surface of each push button, and reference numeral 14 indicates a stopper protruding from the side of each push button.

The movable piece 3 has a recess 10 formed on its lower surface, and a cross-shaped protrusion 4 having a triangular cross section formed on its upper surface.

Reference numeral 8 denotes a base, on the upper surface of which a printed circuit board 7 is layered, and a protrusion 9 extending from the center of the base 8.
is installed protrudingly.

Reference numeral 5 denotes a cover fixed on the base 8, in which a fitting hole 5a for each of the push buttons 1 is formed;
A cross-shaped recess 6 that fits with the cross-shaped protrusion 4 of the movable piece 3 is formed at a position facing the movable piece 3 on the lower surface of the center thereof.

The printed circuit board 7 has two circuit boards as shown in FIG. 4, for example.
It is a combination of sheets, and electrodes 7a are formed at positions corresponding to the contacts 13 of each of the push buttons to make contact with the contacts.

12 is a connection terminal.

Then, the protrusion 9 of the base 8 on which the printed circuit board 7 is layered
The elastic body 11 is arranged to surround the elastic body 11, and the recess 6 of the movable piece 3 is fitted onto the protrusion 9 to support the movable piece 3 and each push button 1, and the cover 5 is placed over the elastic body 11. A cross-shaped recess 6 on the lower center surface of the cover and a cross-shaped protrusion 4 on the movable piece 3
The base 8
and cover 5 are fixed with mounting screws 15 or the like.

FIG. 5 shows an embodiment different from the above.

In this embodiment, a protrusion 9' is provided protruding from the lower surface of the movable piece 3, and its lower end is fitted and supported in a recess 10' formed in the base 8. The configuration of the letter-shaped recess 6 is similar to the embodiment shown in FIGS. 3 and 4.

FIGS. 6 and 7 show further different embodiments.

In this embodiment, a cross-shaped protrusion 4' is formed on the lower surface of the movable piece 3, a cross-shaped recess 6' is formed on the upper surface of a protrusion 9 protruding from the center of the waist base 8, and the cross-shaped protrusion 4' and cross-shaped recess 6
′ are engaged with each other.

As described above, the multi-button switch of the present invention has a plurality of pushbuttons with contacts attached to the bottom surface concentrically arranged around a movable piece and integrated with the movable piece through a thin hinge part,
The movable piece is supported on a base on which a printed circuit board is layered via an elastic body and a protrusion, and the movable piece is covered with a cover fixed to the base, and the movable piece and the cover or the movable piece and the base side Since a cross-shaped protrusion and a cross-shaped recess are provided between the protrusion and the two are engaged, when either push button is pressed, the contact point on the bottom surface of the push button comes into contact with the electrode on the printed circuit board. Even if the movable piece is tilted by pressing the push button, the push button always maintains a predetermined position relative to the cover and base due to the engagement between the cross-shaped protrusion and the cross-shaped recess. You can always do the right thing.
