Simple Relay Switch Circuit Diagram Relay is an electro mechanically operated switch, however other operating principles are also used in relays, such as solid state relays. A Relay is generally used when it is required to control a circuit by a separate low power signal, or when several circuits must be controlled by one signal. Simple Relay Circuit – Circuit Wiring Diagrams The following schematic illustrates the Simple Relay Circuit Diagram. When the switch S is closed in a relay circuit, current flows in the coil, causing a strong magnetic field around the coil. The soft iron bar in the lamp circuit is attracted toward the right end of the electromagnet and makes contact with the conductor at A. How to Use Relays to Control Electronic Line Voltage Circuits Here is a schematic diagram for a simple circuit that uses a 9 VDC circuit with a handheld pushbutton to turn a 120 VAC lamp on and off. The relay in the circuit has a coil rated for 9 VDC and a switch rating of 10 A at 117 VAC. Thus, only 9 VDC passes through the handheld pushbutton. How To Build Time Delay Relay Circuit Electronics Hub A simple time delay relay circuit is designed here. With the help of this circuit, a user controlled delay to relay can be given. Time delay relays are very useful in protecting sensitive electronic devices from spikes and surges. Relay Switch Circuit and Relay Switching Circuit As well as switching relay coils and other such loads with NPN Bipolar Transistors, we can also switch them using PNP Bipolar Transistors. The PNP relay switch circuit is no different to the NPN relay switching circuit in terms of its ability to control the relays coil. However, it does require different polarities of operating voltages. How to Build a Relay Driver Circuit We will also go over a generic relay driver which can operate from either AC or DC voltage and operate both AC and DC relays. All the circuits are relatively simple to understand. DC Relay Driver Circuit. We will first go over how to build a relay driver circuit for relays which operate from DC power.
