Tips: Working principle of electromagnetic relay
Electromagnetic replay uses electromagnet to control “on” or “off” status of operating circuit. Thus how an electromagnetic relay works specifically?
Electromagnetic relay consists of electromagnet, armature, spring, movable contact and stationary contact. When applying voltage to both ends of a coil, the coil will be flowed with current and generate electromagnetic effect. The electromagnet will attract armature to the iron core against tension of spring, so as to pull the movable contact of the armature to the stationary contact (normally open contact, or NO). When users cut off power, attraction of the electromagnet will disappear and the armature will restore its position under tension of the spring to release the movable contract from the stationary contact (normally closed contract or NC). The pulling and releasing are used to control opening and closing of the circuit. Normally open and closed contacts respectively refer to the stationary contract when the coil is cut off from power and the stationery contract when the coil is connected to power.
