An electronic switch circuit with a gas shut-off valve solenoid for use in a leisure vehicle such as a caravan, campervan or horse box. The solenoid needs an initial period of high voltage to activate, and then voltage is reduced. This reduces the electrical power needed to maintain the solenoid in the shut-off state. The circuit may also include a DC-DC converter and MOSFET transistors or power switch integrated circuits, where the transistors or power switches minimise power loss and voltage drop. |
