12v Spst Relay Wiring Diagram. In figure 1 no DC voltage is applied to points A and B therefore no current flows through the coil of the relay the contact stays in the close position and the fan will be switched ON because it is connected to the 220V. This relay will be identified as having a middle 87b spade or no middle spade at all.
This relay will be identified as having a middle 87b spade or no middle spade at all. If the contact is broken with the relay at rest then the relay is referred to as Normally Open NO and if. SPST Form A.

4RA could you advise with the wiring of a relay hella 4ra as I tried to wire the relay as per instructions but could not get it to function. Yeah also several books are given that book can steal the reader center therefore much. It reveals the components of the circuit as simplified shapes and also the power and signal connections in between the tools. If you need a relay diagram that is not included in the 76 relay wiring diagrams shown below please search our forums or post a request for a new relay diagram in our Relay Forum.
