Abstract

The invention relates to an electrical or electronic level indicator which is positioned in a plug-in housing 24. The plug-in housing 24 is closed with a cover 10. This cover 10 is furnished with a handle bar 11, which serves as an aid for removing the cover 10. Positioned inside the cover 10 are rotating cylindrical pins 12, 13 which allow the potentiometers 32 and/or switches 33 to be adjusted. The electrical components 32, 33 are positioned on a circuit board 30, which lies inside the cover 10.

Claims

1. Electrical or electronic level indicator that is positioned in a plug-in housing with a cover, wherein

a handle bar projecting outwardly from the cover (10) of an electronic holding fixture is provided, such that the handle bar (11) serves as an aid for removing the cover (10), but also contains externally accessible control elements (12, 13) for the mechanical adjustment of electronic components (32, 33) located beneath the cover (10).

2. Electrical or electronic level indicator according to claim 1, wherein

the electrical components are potentiometers (12) and/or rotary switches (13).

3. Electrical or electronic level indicator according to claim 1, wherein

the control elements are cylindrical pins (12, 13), which are positioned with an axially parallel disposition and a rotating mount in recesses in the handle bar (11) and which have a groove on their outer ends, in accordance with the screw type, to allow their adjustment with a screwdriver.

4. Electrical or electronic level indicator according to claim 1, wherein

the electrical components are provided on a circuit board (30), which is positioned

5. Electrical or electronic level indicator according to claim 4, wherein

the electrical components (12, 13) are positioned on the side of the circuit board (30) facing the handle bar (11) and have insertion grooves in which the control elements (12, 13) engage in a force-fitting and form-fitting manner, using coupling elements (12b, 13b) that correspond to said insertion grooves (32a, 33a).

6. Electrical or electronic level indicator according to claim 1, wherein

the control elements (12, 13) are arranged in a row and the cover (10) has at least one window (22), which runs parallel to this row and in which are positioned outwardly accessible connecting contacts (23) for the measuring device.

7. Electrical or electronic level indicator according to claim 5, wherein

the circuit board, along with the electrical components (12b, 13b), is secured to the back of the cover (10) in a detachable manner, preferably with screws.
