3, industrial control relays
????The main control functions are done by a universal AC relay. The relay is usually driven by a button or limit switch. The contact of the relay can control the solenoid valve, the larger start motor and the indicator light.
2, household appliances
??Air conditioning relays are mainly used to control the compressor motor, fan motor and cooling pump motor to perform the relevant control functions.
Give the following three examples:
1, the field of cars
????The more common relays are: start-up motor starting relay, loudspeaker relay, motor or generator circuit breaker, charge voltage and current regulation relay, change signal flash relay, light brightness control relay and air conditioning control relay, sliding door automatic opening and closing control Relay; glass window lift control relay.
A relay is a device that closes or disconnects a circuit by means of the effect of current for automatic protection and automatic control. In most cases, the relay is an electromagnet, and the armature of the electromagnet can close or disconnect one or more points of contact. When there is current in the winding of the electromagnet, the armature is attracted by the electromagnet, thus changing the state of the contact.
