Description

[Detailed Description of the Invention] This invention relates to a rectangular pushbutton switch comprising a pushbutton body connected to an operating shaft of the switch, and a pushbutton cap fitted onto the pushbutton body.

There are various structures of pushbutton switches in which a large number of pushbuttons are arranged on one operation panel.

In particular, for the type of installation in which a hole is drilled in the operation panel and the pushbutton body connected to the operation shaft of the switch mounted on the frame side is exposed to the outside through the hole, the condition of the switch installation is particularly important. The operating axis may tilt slightly.

For this reason, the pushbutton bodies attached to the operation shaft are arranged on the operation panel while being tilted, so that each switch is attached in a different orientation and is misaligned.

In particular, in the case of rectangular push buttons, there is a problem that the orientation of the push button caps on the operation panel is misaligned.

Therefore, there is a mounting method in which the clearance between the hole and the pushbutton body is reduced, and the pushbutton body is forcibly aligned with the inner edge of the hole. Friction occurs between the switch and the hole, and the switch operation is hindered by the frictional resistance, causing problems such as the switch becoming unable to return.

Therefore, there is a method in which the pushbutton body is connected to the operating shaft via a coil spring, etc., and the posture of the pushbutton body is maintained correctly even if the operating shaft is tilted, but this method has a complicated structure and is costly. It has the disadvantage of being expensive.

This invention was made based on the above circumstances, and it gives flexibility in the connection between the pushbutton cap that fits on the pushbutton body and the pushbutton body, and improves the appearance of the alignment and direction of the pushbutton. The purpose of this invention is to provide a low-cost rectangular pushbutton switch that has been improved to achieve uniformity.

This invention will be explained in detail below based on the illustrated embodiments.

In the figure, reference numeral 1 denotes a bush type switch, and a neck portion 3a of a plastic push button body 3 is connected to this operating shaft 2.

The pushbutton body 3 has a rectangular block shape, and a pushbutton cap 4 is fitted onto the pushbutton body 3.

The above pushbutton cap 4 has channels fitted on both the upper and lower sides.
4a, and its edge 4b is connected to support seats 3b formed at the four corners of the push button body 3.
In contrast, it is supported in the direction of the pressing force.

The fitting portion 3C of the push button body 3 that is fitted into the push button cap 4 has a shape with both corners cut out,
A cut groove 3d is provided on both upper and lower sides of the cut groove 3.
It is provided with a pair of tongue pieces 3e formed by d.

The tongue piece 3e has an arc-shaped engagement claw 3f projecting outward from its tip, and is configured to be able to expand elastically due to its material properties.

In the figure, reference numeral 5 indicates an operation panel, 6 indicates a mounting hole provided on the operation panel 5, and 7 indicates a bush provided on the back side of the mounting hole 6.

Therefore, the pushbutton cap 4 has the engaging claw 3f.
By pushing it into the cut groove 3d and introducing it into the channel fitting groove 4a, it is fitted into the push button main body 3, and the end edge 4b is supported on the support seat 3b.

In such a configuration, for example, even if the switch 1 is installed unevenly and the operating shaft 2 is tilted and the pushbutton body 3 is tilted, the pushbutton cap 4 cannot be moved in the longitudinal direction of the channel fitting groove 1a. By sliding it slightly, you can make minute left and right position adjustments as shown in Figure 3.

In addition, by slightly twisting the push button cap 4 as shown in FIG. 4, the contact position of the bottom surface of the channel fitting groove 4a with respect to the arc surface of the tip of the engaging claw 3f can be shifted, thereby changing the direction of the push button (left and right). , up and down) can be adjusted.

In this way, the pushbuttons arranged on the operation panel 5 are aligned and their directions are adjusted.

As described in detail above, this invention includes a pushbutton body connected to an operating shaft of a switch, and a pushbutton cap fitted onto the pushbutton body, wherein the pushbutton body is connected to the pushbutton cap. The push button cap is provided with support seats at the four corners that receive the edges in the pressing force direction, and a pair of tongue pieces that elastically expand in a direction perpendicular to the pressing force direction are provided in the portion fitted to the push button cap. The push button cap is provided with a channel fitting groove extending left and right, and the tongue piece is fitted in the channel fitting groove and rotates the push button cap with respect to the tongue piece. Since the engaging portion with the tip shaped like an arc is formed outward, it is possible to align rectangular pushbutton switches on the operation panel without increasing the number of parts or increasing costs. This can have the practical effect of being able to be arranged in a directionally aligned state.
