<p>The method involves applying an auxiliary voltage to an encoder in a closed switch-position. A series of pulses coding the level of the auxiliary voltage is generated for transmission to a decoder, where the auxiliary voltage is coded by two uniform pulse edges of two different pulses (31, 32), which are generated with different pulse lengths. The level of the auxiliary voltage is coded by a delay time (t) between uniform edges of the two pulses, where the delay time is given by linear characteristics. An independent claim is also included for a device for transmission of a binary switching-position of a switch.</p> |
