The present invention relates to an electronic switching module that can directly be mounted without any modifications, instead of the electromagnetic DC relays used in various vehicles. The electronic switching module ( 15 ) consists of a plastic casing ( 1 ) protecting said module against the external environmental conditions, an aluminium block ( 2 ) preventing over-heating of the electronic circuit, a semiconductor switching element transistor ( 3 ), a printed circuit card ( 4 ) on which the electronic circuit elements are arranged, a cover ( 5 ) wherein said printed circuit card is placed and the contacts ( 6 ) to provide the connection to the power circuit.
