The relay is divided into AC and DC. According to its working power supply, the choice is to use AC relay or DC relay. As an Automotive Relay Manufacturer, let us explain to you.
The reed switch relay has two types of contacts: normally open contact (H) and change contact (Z). The control group has single group, two groups, three groups, etc. Its working principle is very simple, using permanent magnet. The magnet or the magnetic field generated by the energized coil can convert its normally open contact operation into a normally closed state to turn on the control circuit.
In general, the reed switch relay has a small rated capacity and can only be used as a small control current for the control signal loop. When used as a control loop signal, there is no rated operating voltage parameter.
