Note:

Product coil is excited by positive and negative pluse,500mS≤t≤1S.long time continuous energizing is not allowed. Operation frequency should be no more than 6 ops/min. It`s square pulse(“+” connect with positive pulse, “-” connect with negative pulse) and positive pulse makes the contact close while negative pulse makes the contact open after the excitation ,the permanent magnet in product keeps the state of the contact.
