DXM-2A type signal relayDetailed product description：

Application of DXM-2A Signal Relay
DXM-2A signal relay is used in DC operation protection and automatic control circuits as an action indicator for remote reset.

Working principle and structure of DXM-2A signal relay
2.1 The relay is a reed switch type relay. It consists of a reed switch, a working winding, a release winding, a self-locking permanent magnet, and an indicator light. When the working winding is conducting, the magnetic field generated by the coil is of the same polarity as the permanent magnet placed inside the coil, and the magnetic flux is superimposed, causing the contacts inside the reed switch to close and the red signal light to turn on. After the working winding loses power, the contacts are held by permanent magnets. When the winding is released for conduction, the magnet generated by the coil has the opposite polarity to the permanent magnet, causing the contact to return and the signal light to turn off.
2.2 Relays have two structures:
2.2.1 Protruding plug-in structure. Adopting Aji JK-5 shell (horizontal), its outline and opening diagram are shown inAppendix IThe internal wiring of the relay is shown in Figure 1.
2.2.2 Embedded plug-in structure (with/Q in the model). Using the Xuji A11K shell, its external shape and opening diagram are shown inAppendix IIThe internal wiring of the relay is shown in Figure 2.
