The operation unit 1 sends out an operation signal by being operated, and has a substantially flat plate 2 and a pushing means 3 arranged at a substantially central portion thereof. plate
Reference numeral 2 is detachable from a main body 12 that houses a detection unit 6 which will be described later, and is fixed to a wall of a room to cover the main body 12, and is made of resin or metal. Pushing means 3
Is an operation signal that is sent to the detection unit 6 to be described later by being pushed. The flat operation piece 4a and the operation piece 4a
A flat plate-like detected piece 4b which is connected to the operation piece 4a and a pushing piece 4c which is also connected to the operation piece 4a and pushes a reversing spring 5 described later. An operation body 4 having a and an inversion spring 5 thereof are provided. The operation piece 4a and the pushing piece 4c are made of resin or metal, and the detected piece 4b
Are formed of a conductive material such as aluminum.

As shown in FIG. 5, the reversing spring 5 has a displacement load curve having a maximum value of the load at a predetermined displacement at the time of pushing, and is made of a metallic material having a spring property, as shown in FIG.
As shown in FIG. That is,
A fixed piece 5a fixed to the plate 2, a connecting piece 5b pushed by the pushing piece 4c, and a support piece which serves as a support for reversing.
5c, a reversing spring body 5d for holding the fixed piece 5a, the connecting piece 5b, and the support piece 5c. The displacement load curve in Fig. 5 shows that the load is 0 at the beginning of pushing in the direction A and the maximum value of the load is 3 when the displacement is 1.5 mm.
50 gf, then the load decreases once, but the load increases again toward the end of indentation with a displacement of 3 mm.

The detection section 6 receives an operation signal from the operation section 1 and outputs a detection signal, and is composed of an electrostatic sensor 7 and a detection circuit 7c. The electrostatic sensor 7 is formed by attaching two substantially apple-shaped copper plates 7b, 7b to a printed circuit board 7a and detects a change in electrostatic capacitance. The detection circuit 7c amplifies a change in the electrostatic capacitance of the electrostatic sensor 7, sets a threshold value of the electrostatic capacitance, and outputs a detection signal for controlling an electric switching unit 9 described later. That is, if the electrostatic capacitance detected by the electrostatic sensor 7 is larger than the threshold value of the electrostatic capacitance, a detection signal is output. The capacitance increases as the detected piece 4b of the operation body 4 approaches the electrostatic sensor 7.

The electric switching section 8 turns on and off electricity based on a detection signal from the detection section 6, and is formed of a relay having contacts. This relay operates by an electrical detection signal. Further, 9 is a display part, which is formed by an LED,

Next, the operation of this one will be described.
When the operation piece 4a of the operation body 4 of the operation portion 1 is pushed in the direction A, the pushing piece 4c pushes the connecting piece 5b of the reversing spring 5. As a result, the reversing spring 5 is deformed by the supporting piece 5c and the reversing spring body
5d will be reversed. As shown in FIG. 5, the displacement load curve at that time has a maximum load value of 350 at a displacement of 1.5 mm.
Since it has gf, the operator can surely feel the actual operation. That is, an appropriate click feeling can be felt when overcoming this maximum value, and since displacement is possible even after the maximum value, a feeling of being jammed is not felt and a good operational feeling is obtained. And
When the operation body 4 moves in the A direction, the detected piece 4b approaches the electrostatic sensor 7 of the detection unit 6, and the detection unit 6 receives an operation signal in the form of a change in electrostatic capacitance, As a result, the detection unit 6 sends a detection signal to the electric switching unit 8.
Therefore, the electrical switching unit 8 turns on and off electricity based on the detection signal. That is, when the detection signal is received,
When electricity is energized, it is cut off, and when electricity is cut off, it is energized.

In this device, since the operation unit 1 and the detection unit 6 are not mechanically connected, the structure of the contacts of the electric switching unit 8 does not affect the operation feeling of the operation unit 1, and the operation unit 1
The operation feeling of can be designed arbitrarily. In addition, since this operation unit 1 is detachable from the main body unit 12 that houses the detection unit 6 etc., the design of the operation unit can be easily changed according to the installation location of this switch, and the operation unit can be easily changed. 1
No electrical work is required to replace the.

Next, a second embodiment of the present invention will be described with reference to FIGS.
It will be described based on. In this embodiment, the shape of the reversing spring is changed.

Reference numeral 13 denotes a reversing spring, which is formed of a leaf spring 14 and a disc spring 15. The leaf spring 14 is made of a thin and long spring material, and one end 14a thereof is fixed to the plate 2. . The disc spring 15 is formed of a thin, substantially hemispherical spring material, and the end surface 15a is fixed to the operation piece 4a of the operation body 4 and the apex 15b is pressed against the other end 14b of the leaf spring 14. Further, the operation body 4 does not have the pushing piece 4c.

This one has the displacement load curve shown in FIG. 5 as the disc spring 15 is reversed by pushing the operating piece 4a of the operating body 4. Compared with the reversing spring of the first embodiment, the number of parts is increased, but the structure of each part is simple.

The displacement load curve of the operating portion is not limited to the one shown in the embodiment, but one having another displacement load curve or a finger of a human body operating without pushing the operation body. A structure in which the detection unit detects a change in capacitance caused by touching one piece is also conceivable. Further, the operation signal between the operation unit and the detection unit has been described as one that utilizes the change in capacitance, but the operation signal is not limited to this. It suffices to transmit the fact that the operation portion is operated to the detection portion without mechanical connection by detecting the heat signal with the heat sensitive element.

[0026]

In the switch according to the first aspect of the present invention, an operation signal is sent to the detection section by operating the operation section, and as a result, the electric switching section turns on and off electricity, so that the operation feeling of the operation section is electric. Since it can be arbitrarily set without being affected by the structure of the opening / closing section, a desired operation feeling can be obtained.

In addition to the effect of claim 1, the switch according to claim 2 can separate the operation part from the detection part, so that the shape of the operation part can be easily changed. It is possible to select operation parts of various shapes.

In addition to the effect of claim 1 or 2, the switch according to claim 3 has a displacement load curve in which the operating portion has a maximum value of the load by applying a predetermined displacement, so that Since it is possible to feel completion, it is easy to give the user a sense of security that the operation has been performed.

In addition to the effect of claim 3, the switch according to claim 4 can achieve the displacement load curve by the deformation of the reversing spring, so that it can be realized at low cost.

In addition to the effect of any one of the first to fourth aspects, the switch according to the fifth aspect has a compact electric switching part, so that the overall size of the switch can be reduced.
