Abstract
A control element for switching and controlling an electrical appliance having a cover panel includes a support (4) for receiving a top part, which can be attached and removed. The support can be glued onto the front panel (2), which need have no openings. Elements (14, 15, 16, 17) are in the top part for causing an indirect control transmission through the front panel, with sensors (5, 6, 7, 8, 9, 21, 22) behind the front panel (2) electrically sensing the indirect control transmissions and carrying out operational functions of the electrical appliance.
Claims13
A control element for an electrical appliance of a type having a front panel, said control element comprising:
- a rotatable upper part including a mount;
- a support for being adhered to a front side of the front panel and for being selectively attached to the mount for allowing the upper part to be rotatable relative to the support and the front panel;
- transmitting means mounted on the upper part for moving with the upper part and thereby causing an indirect transmission through the front panel indicative of rotation of the upper part without being linked to a structural member passing through an aperture in the front panel;
- a sensor positioned behind the front panel for sensing the indirect transmission indicative of rotation of the upper part and for controlling the electrical appliance in response to changes in position of the upper part, whereby the control element can be used on a front panel that has no openings therethrough.
