HW-YT Electromagnetic Relay

HW-YT Electromagnetic Relay is an electronically controlled switch device composed of electromagnet and contacts. It can play the role of switch, protection, opening and closing in the circuit, and controls the action of the electromagnet through the magnitude of the current, thereby controlling the opening and closing of the contacts.

Electromagnetic relays have the advantages of small size, sensitivity and reliability, convenient operation, and wide control range. They are widely used in automation control systems in the fields of machinery, electricity, railways, rail transit, and housing, and are indispensable basic accessories.
