AUTOMATIC CHANGE SWITCH USING CONTACTOR AND PHASE CHANGE SYSTEM The contactor is an electromagnetic component. It works like a switch inside a circuit by establishing or interrupting the flow of current. The role of a day/night or off-peak contactor is to automatically switch on high-consumption electrical equipment such as a radiator, a refrigerator, a washing machine, a hot water tank, a dishwasher or an oven. when the price per kilowatt per hour is low. This appliance has three setting options: automatic on, off and manual on (during peak hours). It can be turned on manually or programmed automatically to run.Depending on the model, it may have integrated open or closed auxiliary contacts. It can support the addition of add-ons or auxiliary blocks that will only be used for remote control or signaling. A contactor consists of a coil, a return spring, 2 to 4 power contacts or poles (unipolar, bipolar, three-pole, four-pole), a magnetic circuit consisting of a fixed magnet and a moving magnet (fixed armature and mobile), a phase shift ring which stabilizes the vibrations of the coils supplied with alternating current as well as the open or closed auxiliary contacts.The contactor coil can be powered by both alternating current and direct current (from 24 to 400 V). The coil is generally powered during off-peak hours. It generates a magnetic field and the mobile part of its armature is attracted against the rigid part. Depending on the model, the contacts then close or open. If the coil is not energized, which is usually the case during peak hours, the return spring divides the two portions of the armature and keeps the power contacts open or closed. This mechanism allows an electricity supplier to control the commissioning of its customer's electrical appliances if the latter has previously subscribed to a day/night subscription.
