Abstract
A control panel having a momentary push-button switch matrix in combination with a rotary switch, which is coupled to the switch matrix by a pulser that generates a signal similar to that of a selected momentary push-button such that the selection of a rotary switch position will generate a signal similar to that of a momentary push-button.
Claims17
A control panel comprising:
- a momentary push-button switch matrix comprising multiple send electrodes and multiple receive electrodes arranged such that the send electrodes and receive electrodes form multiple intersections, momentary push-button switches located at least some of the intersections to couple the corresponding send and receive electrodes upon the actuation of the corresponding momentary push-button switch, and rotary switch contacts provided on at least some of the receive electrodes;
- a rotary switch having an input and a rotatable contact that can be rotated to electrically couple with at least some of the rotary switch contacts;
- and
- a pulser having an input coupled to at least one of the send electrodes and an output coupled to the input of the rotary switch and generating an output signal similar to that of the momentary push-buttons in response to a trigger signal.

A rotary switch assembly comprising:
- a rotary switch having an input and a rotatable contact that can be rotated to multiple contact positions;
- and
- a pulser having an input for coupling to at least a send electrode of a momentary push-button switch matrix and an output coupled to the input of the rotary switch and generating an output signal similar to that of a momentary push-button in a momentary push-button switch matrix.
