Abstract
A device for closing or opening two or more main switches of corresponding electrical power supply circuits of related electrical devices includes a plate having at least two capacitive touch contact areas, and a control circuit configured to control two or more additional switches so that, in the event that only one of the contact areas is touched, only the corresponding main switch is opened or closed, while in the event of a combined touching of at least two of the contact areas, one of the additional switches is opened or closed.
Claims6
A device for opening or closing a plurality of main switches of electrical power supply circuits, comprising:
- a plate having a plurality of touch contact areas of capacitive type, wherein an individual touching of each of said plurality of touch contact areas causes the opening or closing of a corresponding main switch;
- and
- a control circuit;
- wherein said control circuit is configured to control a plurality of additional switches, so as to cause:
- when only one of said plurality of touch contact areas is touched, only the corresponding main switch is opened or closed, and
- when a combined touching of at least some of said plurality of touch contact areas occurs, one of said plurality of additional switches is opened or closed but not one of the plurality of said main switches,
- wherein the combined touching identifies a condition in which at least two of said plurality of touch contact areas are touched simultaneously or within a first predetermined time interval, and
- wherein maintaining said combined touching for a different amount of time causes a selective opening or closing of another one of said plurality of additional switches.
