The invention relates to a method for voltage encoding of switching states of a switching unit (12) which has at least three switching elements (14), wherein a circuit arrangement (10) has an input connection (22) for each of the switching elements (14), wherein the circuit arrangement (10) has a reduced number of output connections (28, 30) corresponding to the number of switching elements (14), and wherein the circuit arrangement (10) individually assigns exactly one combination of voltage levels at the output connections (28, 30) to each switched-on switching state of each switching element (14).According to the invention, each input terminal (22, 24, 26) is electrically coupled to each output terminal (28, 30) by means of a resistor network (32), wherein the resistor network (32) has a series connection of at least two measuring resistors (R4, R5, R8, R9) for each output terminal (28, 30), wherein a first series connection terminal (38, 42) is electrically coupled to exactly one respective output terminal (28, 30), and wherein second series connection terminals (40, 44) are electrically coupled to each other via a coupling resistor (R3, R7).

The embodiment of the present application provides a multi-key detection method and a multi-key device and a multi-key system thereof, which relate to the field of key detection. By obtaining the first level information of multiple keys, the first level information is stored in a preset storage variable; based on a preset time interval, the first level information corresponding to each key is periodically read from the storage variable; a key variable is assigned to each key, the second level information stored in the key variable corresponding to each key is shifted to the high position by a preset number of bits, and calculation information is supplemented in the low position of the key variable; the calculation information and the first level information are calculated to obtain a calculation result, and the calculation result is used as the second level information to replace the calculation information and stored in the key variable; within the preset filtering time, when a preset number of identical key states appear continuously in the key variable corresponding to the key, the key state change corresponding to the key is detected to be valid, which can improve execution efficiency.
