The AC-DC converter 10 includes components such as a rectifier, a capacitor, a power transistor, and a heat sink (not shown). These components are other components whose height from the circuit board P3 is provided on the circuit boards P1 to P3. Higher than

  Further, on the back side of the second circuit board P2, a pair of relays 9 for controlling energization to the load devices L1 and L2, respectively, a terminal plate 33 for connecting the AC power supply AC and the load devices L1 and L2, A remote control terminal 34 including a modular jack is mounted. A second connector 35 is mounted on the front side of the second circuit board P2, and the second circuit board P2 and the third circuit board P3 are electrically connected by the connector 35. In addition, each terminal board 33 comprises what is called a quick connection terminal with which the core wire of the electric wire inserted from the back side of the container body 7 is connected with the lock spring which is not illustrated.

  Here, as shown in FIG. 1, the second circuit board P2 is a lower left part, and a notch is formed at a position corresponding to a region where the components of the AC-DC converter 10 are mounted on the third circuit board P3. By forming 36, it is formed in a substantially L shape as a whole. As shown in FIGS. 8 and 9, the second circuit board P2 and the third circuit board P3 replace the component parts of the AC-DC converter 10 mounted on the third circuit board P3 with the second circuit board P3.

Further, the operation panel 15 covering the front surface of the container body 7 is entirely formed of a light-transmitting material to form a light transmission portion. Therefore, the light from the LED 37 is a light transmission portion 38 of the container body 7. And it will be taken out through the operation panel 15 forward. Note that it is not essential that the operation panel 15 has light transmittance as a whole, as long as at least a portion corresponding to the LED 37 functions as a light transmission portion that extracts light from the LED 37 forward.

  According to this configuration, the user can easily understand the positions of the operation units 2a and 2b even from the front side of the operation panel 15 by the light from the LED 37, and any part of the operation panel 15 may be touched during operation. Can be easily recognized. In addition, by using the LED 37 having different emission colors in the first operation unit 2a and the second operation unit 2b, it is easy to distinguish both the operation units 2a and 2b, and control states of the load devices L1 and L2 ( It is possible to make it possible to visually recognize the control state of each load device L1, L2 by changing the lighting state (emission color, etc.) of the corresponding LED 37 according to the on / off state. is there. Furthermore, if the light transmitting portion 38 of the container 7 or the operation panel 15 is formed in an arbitrary pattern or character shape, the surface of the operation panel 15 can be made to emit light in an arbitrary pattern or character shape.

  In the present embodiment, since the third circuit board P3 is interposed between the first circuit board P1 and the second circuit board P2, the ground pattern formed on the third circuit board P3 ( (Not shown) can be used as a shield. That is, since the detection circuits 3a and 3b formed on the first circuit board P1 detect minute changes in the electrical state of the detection electrodes 8a and 8b, they are mounted on the second circuit board P2. If the noise generated during the operation of the relay 9 affects the detection circuits 3a and 3b, there is a risk of false detection. According to the above configuration, the noise is blocked by the ground pattern of the third circuit board P3. The influence of noise on the detection circuits 3a and 3b can be reduced.

  By the way, in the above-described embodiment, the example in which the cutout portion 36 is formed in the circuit board P2 so as to avoid interference with the components of the AC-DC converter 10, but the present invention is not limited to this example. Need only be formed so as to avoid interference with at least one component mounted on the circuit boards P1 and P3 other than the circuit board P2 in which the notches 36 are formed. For example, a hole penetrating the circuit board P2 It may be. Further, the notch 36 is not limited to the second circuit board P2, but may be any one that is formed on at least one circuit board P1 to P3.

  In the above embodiment, the two-circuit, two-contact type touch switch device 1 capable of on / off control of the two load devices L1 and L2 has been exemplified. However, in addition to this, for example, as shown in FIG. The present invention can be applied to various touch switch devices 1 such as a one-circuit one-contact type touch switch device 1 used for on / off control of the load device L1.
