0.2W Electromagnetic Relay Switch With CQC certification

0.2W Electromagnetic Relay Switch With CQC certification Relay is an automatic control device that will change by leaps and bounds in output when the input quantity (electrical, magnetic, acoustic, light, thermal) reaches a certain value. Power relays: The relays powered by electromagnetic. Direct-current relays: The relays need input of direct current. Alternating-current relays: The ralays need input of alternating current. Polar relays: The control of the relay is
