The main difference in circuitry between electronic control devices and conventional switches is whether they are manual or not.

No. Electronic control devices and traditional switches in the circuit is the main difference between electronic control devices need a separate power supply and the need to use various forms of sensors but the switch is automatic, while the traditional switch needs to be a collective power supply, sensors only need the most primitive sensors can be there is not much requirement for the switch is manual. Electronic controller is an important electronic product components, in electronic production has a wide range of applications, in people's daily lives play a very important role.
