Description

TECHNICAL FIELD The present invention relates to a seesaw type switch device suitable for use in a dimmer or the like.

[Prior Art] As a switch device used for a dimmer or the like, a switch device provided with a seesaw-type push button for up dimming and down dimming operations is used.

At this time, the seesaw-type switch device incorporates a power control element such as a triac or a thyristor that constitutes a phase control element of the dimming circuit.

However, in the conventional seesaw-type switch device, as described in JP-A-59-5530, the above-mentioned triac is fixed to the back surface of the mounting frame for embedding and fixing the switching device in a wall surface, etc. There is something that doubles as a heat sink for a triac. As for the structure of the seesaw type switch device, as described in Japanese Utility Model Laid-Open No. 165628/1984, the fulcrum part of the button is located at the fulcrum receiving part provided in the frame, and the right side inner surface and left side of the button are There is a seesaw button structure in which an elastic pressing piece located on the inner surface of the part is made to act.

[Problems to be Solved by the Invention] However, in the above-described conventional seesaw-type switch device, since the seesaw-type push button is arranged in the mounting frame, a relatively large window hole for inserting the push button main body is attached. There is an opening in the frame. Therefore, the heat dissipation area of the mounting frame is reduced,
It is difficult to secure sufficient heat dissipation performance.

As another mounting frame for the seesaw type switch device, there is one that can be housed in a recess instead of being fitted with the push button body, and this mounting frame without a window hole is mounted as the mounting frame for fixing the above-mentioned triac. It can be used. However, in this case, the concave portion of the mounting frame is hard to function as a heat radiation portion due to the retention of hot air, and it is difficult to expect sufficient heat radiation performance after all.

In a seesaw-type switch device, the center of the button body is swingably supported, and a spring is arranged between the back surface of the button body and the front surface of the mounting frame. The main body is kept in the neutral position, and at the time of operation, either one of the two longitudinal ends of the button main body can be pushed to turn on / off the corresponding switch.

However, in the conventional seesaw-type switch device, due to the shape of the above-mentioned spring, especially the shape of the terminal, a biased elastic force is applied around the central portion of the button body, and the button body is horizontally moved at the neutral position. There is a case where it cannot be kept and it tilts. This is not appropriate in the sense that the operation load and the operation stroke are different between the one side and the other side of the seesaw operation, and the operability is deteriorated.

It is an object of the present invention to secure sufficient heat dissipation performance for a power control element when incorporating the power control element in a seesaw-type switch device.

Also, the present invention keeps the button body horizontal at the neutral position,
It is an object of the present invention to ensure good operability and to provide wiring even after construction by providing a remote control light-receiving section necessary for operating a dimmer with a remote control in a switch mounting frame.

[Means for Solving the Problems] The present invention according to claim 1 is characterized in that a seesaw-type push button having a built-in power control element is arranged on a plane surface of a metal mounting frame, and the power control element is provided. In the seesaw-type switch device disposed in contact with the mounting frame, the seesaw-type push button has support members provided on both sides of the mounting frame with convex vibration center widths provided on both sides in the center width direction of the button body. Supported by the rocking guide part of the button body, and the planar copying parts extending on both sides in the longitudinal direction of the rocking center axis of the button body are flat plate extending on both sides of the rocking guide part of the supporting member. A spring is arranged between the back surface of the button body and the front surface of the mounting frame so that the spring can be brought into contact with the neutral guide portion. According to a second aspect of the present invention, the light receiving portion of the remote control device for adjusting the light in the room where the seesaw-type switch device is arranged is arranged on the room-side surface of the metal mounting frame.

[Operation] According to the present invention as set forth in claim 1, the seesaw-shaped push button is disposed on the mounting frame, and the push button is disposed on the surface of the flat plate, so that the push button is released from the power control element. Heat is efficiently dissipated from the flat plate having good heat dissipation. Also, depending on the shape of the spring, especially the shape of the terminal, from the swing center of the button body,
Even when the button is pushed at a distant point, the planar copying portions extending on both sides in the longitudinal direction of the swing center axis of the button body are provided with a flat neutral guide portion provided on the supporting member by the elastic force of the spring. Pressed against. As a result, as a result of the flat copying portion being abutted so as to follow the flat neutral guide portion,
The button body can be kept horizontal in the neutral position. This makes the operating load and the operating stroke even on one side and the other side of the seesaw operation, so that good operability can be secured. Even if the illuminator itself does not have a remote control function, it is possible to change the brightness of the illumination in an analog manner by using the seesaw-type push button switch of the present invention.
