Refers to the minimum current that the relay can generate the draw action. In normal use, the given current must be slightly greater than the draw current for the relay to be stable To work. The working voltage added to the coil, generally do not exceed 1.5 times of the rated working voltage, otherwise it will produce a large current and burn the coil.

​The relay coil is represented in the circuit by a long box symbol, and if the relay has two coils, two long boxes are drawn side by side. At the same time, mark the relay word symbol "J" in or beside the long box. There are two ways to represent the contacts of relays: one is to draw them directly on one side of the long box, which is more intuitive. The other is to draw each contact into its own control circuit according to the needs of the circuit connection. Usually, the contact of the same relay and the coil side are marked with the same text symbol, and the contact group is numbered to show the difference.

Self-locking and interlocking are achieved by auxiliary contacts of relays. First of all, you need to understand what is called self-locking and what is called interlocking. Self-locking is to short off the button switch of the contactor coil loop with your own contacts, and make the coil loop open continuously after the button switch is released, which is self-locking.

When choosing a relay with QC lead-out method, please do not use soldering to connect the load lead-out end of the relay. If other welding methods are used, it is also necessary to ensure that the heat generated by welding will not affect the function of the magnetic latching relay

Please apply a suitable voltage to the coil according to the coil polarity specified in the manual, otherwise the operating voltage of the relay will increase or even not operate; it needs to be changed When driving the polarity, please use the "-R" type relay.

The factory state of the Magnetic Latching Relay is in the state of action or return, but it may change due to the impact of transportation or relay installation and other factors, so please set it to the state of return or action as required when using it (when the power is connected);

Thermal Reed Relay is a new type of thermal switch that uses thermal magnetic material to detect and control temperature.

Latching refers to "self-locking", which means that after the relay is energized, its state is automatically locked and the circuit is kept connected. Even if the control current is disconnected at this time, its state will not be changed. That is to say, when the power is energized and absorbed, the control current is disconnected, and it remains on until the unlock button is pressed.
