MP2877B Volton Combi Relay
The Volton Combi Relay has been designed to switch a live 12 volt input feed to supply the supplementary socket on the vehicle’s caravan. This unit stops the drain of the vehicles battery when the ignition is turned off as the relay senses the voltage of the vehicle and switches off. It also switches itself on when the vehicle starts up and reaches the required voltage.
