Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a touch control device.

A conventional touch control device generates a signal by touching a touch control switch attached to the surface of a device such as a television stereo with a finger, and controls the device using this signal.

As a result, since the device cannot be preset to a specific state in advance, a dedicated preset switch must be provided, resulting in a complicated structure.

An object of the present invention is to provide a touch control device which has a simple structure and can be preset without such drawbacks.

An embodiment of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a sketch of an embodiment of the present invention.

The button 10 in the figure is a touch control switch attached to the front panel 9 (shaded area) of equipment such as televisions and stereos. A plurality of hot-side electrodes 4 constituting a first electrode are lined up in a line and embedded 1 approximately in the center of the body 2 .

Here, each hot-side electrode 4 protrudes from the surface of the insulator 20, and each hot-side electrode 4 passes through the inside of the insulator 2 using a conductive wire to detect each corresponding tentacle (not shown) inside the front panel 9. connected to the circuit.

Reference numeral 11 denotes a presetting member 5 which is conductive and has a substantially U-shape.
and a conductive rubber plate 6, a hole 8 is bored in the bottom 7 of the member 5 in correspondence with the electrode 4, and the rubber plate 6 is attached to the inner bottom surface.

With the above configuration pressed, if one of the hot side electrodes 4 and the ground side electrode 1 or 3 are touched at the same time, the corresponding one of the hot side electrodes 4 is grounded, and as a result, each of the tentacles A corresponding one of the sensing circuits generates a signal to set the device in a predetermined state.

As described above, the touch control switch 10 can be operated as a normal touch control switch, but as shown in FIG.
It is also possible to preset by attaching the presetting member 11 to 0.

That is, FIG. 2 shows a cross-sectional view of the state in which the presetting member 11 is attached to the touch control switch 10, in which a conductive rubber plate 6 is in contact with one of the hot-side electrodes 4, and one of the hot-side electrodes 4 is in contact with the conductive rubber plate 6. The leg portions 12 of the letter-shaped member 5 sandwich and elastically touch the ground side electrodes 1 and 3, and as a result, the corresponding contact detection circuit generates a signal to connect the device to each hot side. Preset to one of each predetermined state corresponding to the electrode.

In the above, each of the predetermined states corresponds to, for example, in the case of a stereo amplifier, each setting state of a so-called function switch that sets which of the tuner, player, teleco, etc. connected to this amplifier is selected. Can be done.

As described above, the present invention has the excellent effect that by attaching a presetting member with a simple structure to a touch control switch, it is possible to easily preset a device, and it can also be used as a normal touch control switch. has.
