According to the disclosure, an auxiliary voltage which is to be transmitted when the switch position is closed is coded using two identical pulse edges of two different pulses, that is to say using either the two connection edges or the two disconnection edges of the two pulses. As a result, the previously known pulse duration modulation is replaced with modulation of the delay time between the two pulses. The two pulses mentioned can be repeatedly generated inside a basic period, which is independent of the auxiliary voltage, and have, for distinguishing purposes, a connection duration or pulse length which is different but is independent of the auxiliary voltage.10-02-2008
