Modern car engines use electric motors as starting power. It is composed of battery, ignition switch, starting relay, starter, etc. Jump Start Manufacturers introduce that the function of the start system is to convert the electrical energy of the battery into mechanical energy through the starter to start the engine.
1. Start switch Turn on the electromagnetic switch circuit of the starter to make the electromagnetic switch work. The start switch of the gasoline engine is combined with the ignition switch.
2. The starting relay is controlled by the starting relay contact (normally open type) to turn on and off the electromagnetic switch circuit of the starter. The starting switch only controls the starting relay coil circuit, thereby protecting the starting switch. There are single connection type (protection starting switch) and composite Type (protect both the start switch and the starter).
