Description
<Desc/Clms Page number 1>
Elektrisches Wärmekissen.
Die bisher bekannten Ausführungen von elektrischen Wärmekissen haben gewöhnlich mehrere Wärmestufen, welche teils durch Steck-, teils durch Drehschalter betätigt werden.
Die vorliegende Erfindung betrifft eine Vereinfachung durch Verwendung von Druckknöpfen an Stelle der Schalter. Die Möglichkeit hiezu bietet sich dusse geringe Stromstärke bzw. durch den äusserst kleinen Wattverbrauch, wodurch eine schädliche Funkenbildung beim Ein-und Ausschalten gar nicht aufkommen kann.
Die bekannten Druckknöpfe, bestehend aus Unter-und Oberteil, sind wie geschaffen, in diesem Falle die Schalter zu ersetzen. Die Anordnung kann mit beliebig vielen Stromkreisen bzw. Wärmeregulierungen durchgeführt werden. Eine Ausführungsform ist im folgenden an Hand der Zeichnung näher beschrieben.
Auf der Stoffunterlage a sind die Stromleitongen b und c aufgenäht, deren Enden

Electric heat pad.
The previously known designs of electrical heat cushions usually have several heat levels, which are operated partly by plug-in switches and partly by rotary switches.
The present invention relates to simplification by using push buttons in place of switches. The possibility of doing this is offered by the low current strength or the extremely low watt consumption, which means that harmful spark formation cannot occur when switching on and off.
The known push buttons, consisting of a lower part and an upper part, are designed to replace the switches in this case. The arrangement can be carried out with any number of circuits or heat controls. An embodiment is described in more detail below with reference to the drawing.
The Stromleitongen b and c are sewn onto the fabric base a, their ends
EMI1.1
