The relay is a common element in electronic circuit, which often consists of the electric switch drive circuit formed by the transistor, relay and others, and other circuits that can change the working features of the relay or fulfill protection function. The additional circuits of the relay has 3 pattens: 1. The relay parallel RC circuit: the circuit type is shown in figure 1, and it is often used in the circuits that the regulated working voltage is lower than the power supply voltage. When the circuit is closed, the current in the relay coil is increaseing.
