Abstract

A signaling device which generates a selection signal via an analog selection device for choosing a signal range, and a range scale for displaying the signal range chosen by the analog selection device, wherein the range scale includes setting ranges and a transition range, where one setting range of the setting ranges is arranged in an alternating manner with the transition range along the range scale, and the analog selection device is arranged such that selection of a setting range or a transition range along the range scale is selected and the analog selection device defines an analog selection value, and the signaling device additionally detects the analog selection value aided by the selection signal and checks whether this value corresponds to a value allocated to a transition range, and if so, outputs a signal via a signaler.

First claim

The invention claimed is:

1. A signaler which generates a selection signal via an analog selector for choosing a signal range, and a scale for indicating the signal range chosen by the analog selector;
wherein the scale exhibits at least two setting ranges and at least one transition range, a setting range of the at least two setting ranges each being arranged in an alternating manner with, in each instance, a transition range of the at least one transition range along an extent of the scale;
wherein the analog selector is arranged such that a selection of a setting range or a transition range occurs along the extent of the scale such that the analog selector establishes an analog selection value; and
wherein the signaler captures the analog selection value aided by the selection signal and checks whether the captured analog selection value corresponds to a value which has been assigned to a transition range, and, if appropriate, outputs a signal by an included further signaler.

2. The signaler as claimed in the claim 1 , wherein the signaler includes an electronic circuit.

3. The signaler as claimed in claim 1 , wherein the signaler includes a measuring device.

4. The signaler as claimed in claim 3 , wherein the measuring device comprises a temperature-monitoring relay.

5. The signaler as claimed in claim 1 , wherein the extent of the range scale extends circularly.

6. The signaler as claimed in claim 1 , wherein the analog selector is a potentiometer.

7. The signaler as claimed in claim 1 , wherein at least one range of the at least one transition range extends in a direction along the scale which is at most half as large as a direction along which a setting range of the at least two setting ranges extends along the scale.
