DE4400565A1 - Contact or proximity sensor for electronic control e.g. of dimmer switch - Google Patents

Abstract

The contact or proximity sensor for the control of e.g. dimmer circuits and their associated electronics has a sensing element which utilises an electrically insulating material as the core substance (2). The core (2) may therefore be of a naturally occurring insulator e.g. granite, sandstone, gypsum, pebble etc. or a manufactured alternative e.g. concrete, brick, glass, ceramic etc.

Description

In conventional touch sensor switches are elek trically conductive materials such as semiconductors, metals, Metal alloy contact surfaces needed to make a switch trigger function when touched. The downside is that with it an electrical potential is touched. So there is a possible circuit flow when touching the metal sensor at a De of electronics through the human body possible (touch).

With the new medium touch proximity sensor switching Dimmer electronics it is now possible to touch sorfläche from a medium such. B. a mineral (Stone, glass, etc., Electrically non-conductive) to ge design. Absolutely potential-free, no tingling touch.

Solution of the problem or the technical problem

In order to transfer the electrophysical touch effect to a medium, a stone, granite block ( 2 ) is pierced as a contact medium with any dimensions in the middle ( 3 ). A stainless steel tube ( 4 ) is inserted through the hole ( 3 ), to which the sensor cable ( 5 ), which is shielded by the digital dimmer ( 9 ) output ( 7 ), is connected in an electrically conductive manner. Through this tube ( 4 ) current-carrying Lei ter, which are also shielded with the digital dimmer ( 9 ) output ( 7 ) can be carried out without having an influence on the electrophysical touch effect of the medium. Other methods of transferring the contact effect into a medium are as follows: A metal expanding thread bushing is inserted into the bore ( 3 ab) and thus firmly clamped to the medium stone ( 2 ). A screw ( 4 ac) is screwed into this metal threaded bush, to which the sensor line ( 5 ) of the adjustment ( 9 a) is contacted ( 5 ac).

It is also possible the medium with an electrical rule's z. B. to wrap a bare or insulated copper wire ( 4 ad), or to span with a steel band, on which the sensor line ( 5 ) is then also contacted ( 5 ad) to transmit the effect. The medium stone ( 2 ) placed on a metal surface ( 4 ae) also enables transmission ( 5 ae).

If the transmission is ensured by one of the above-mentioned types, different effects on the stone ( 2 ) or through the stone ( 2 ) can now be achieved by comparison ( 9 a).

On the one hand, it is possible to transfer the touch field by mere contact from stone to stone ( 2 a). The touch panel is then embedded in the stones that touch each other. This makes it possible to pile up several stones so that they touch each other and the touch effect is given on each stone.

The touch panel can be integrated into the medium or can be made effective as a proximity effect, radiating beyond the medium. This means that the comparison ( 9 a) is based on masses.

The possibility by a deep bore (3 a) and a metal pin cylinder (4 ab) to produce a dosage of Berührfeldübertrittes, namely un terschiedliche depth of insertion of the metal pin cylinder (4 ab) in the deep hole (3 a) is flat if any.

Due to the different surface area of the metal ( 4 a), there is an equally different dosage of the touch panel crossing when connecting ( 5 a) to ( 5 af), or by ( 5 a) also as a sensor line for contact with the medium stone ( 2 ) Touch is used. ( 5 a) can be of any length due to the interposition of the medium ( 2 ) without having to be shielded.

This makes it possible to galvanically decouple an electrical potential ( 4 af), which can be compared with the medium stone, as a so-called dielectric. The stirring effect occurs when ( 5 ab) is connected to ( 5 af) on the entire low-voltage circuit ( 4 af) with consumer ( 8 a).

The medium-touch proximity sensor switch dimmer electronics enables materials that do not conduct electricity to be touch-selective. Practical applications in wet rooms, as child protection sensors, as wall switches, wall touch sensor switches, proximity switches, etc. . .

Claims (4)

Mineral sensor A mineral (stone) acts as the medium of electronics. With the medium-touch-proximity-sensor-switch-dimmer electronics it is possible to remove the touch sensor surface from a medium such as e.g. B. one Mineral (granite, conglomerate, sandstone, gib, brick, concrete or to shape pebbles etc. Even certain glass or ceramics can be used for this effect turn.
