To drive the relay using an N-channel MOSFET and switch the load between two LEDs, you'll need to make several connections. Here's a step-by-step approach based on your project components:

Connect the MOSFET to the Relay:
- Connect $Q1$ :DRAIN to $K1$ :Coil-1.
- Connect $K1$ :Coil-2 to a positive power supply (let's assume 12V for the relay).
Connect the MOSFET Source to Ground:
- Connect $Q1$ :SOURCE to ground.
Connect the MOSFET Gate to a Control Signal:
- You can drive the gate with a microcontroller or a manual switch. For now, assume you have a control signal: connect this control signal to $Q1$ :GATE through a resistor (e.g., $R1$ with a value of 470 ohms).
Connect the LEDs via the Relay:
- Connect $K1$ :Com-3 to the power rail (e.g., +5V or another suitable voltage for LEDs).
- Connect $K1$ :NO to $LED1$ :A (anode).
- Connect $LED1$ :K (cathode) to ground.
Optional - Connect a Second LED:
- If you have a second LED, similar to $LED1$ , and want to alternate between them, you can connect it through the relay's NC (normally closed) contact:
- Connect $K1$ :NC to the anode of the second LED.
- Connect the cathode of the second LED to ground.

Here's a simple outline of what these connections achieve:

When the control signal is applied to the gate of the MOSFET, it turns on, completing the circuit for the relay coil, thus energizing the relay.
The relay will switch from NC to NO, turning on $LED1$ .
When the MOSFET is off, the second LED (if connected) through the NC contact would be turned on.

ok if i dont have microcontroller

If you don't have a microcontroller to control the N-channel MOSFET, you can use a mechanical switch to manually control the MOSFET gate. Here’s how you can set it up:

Use a Switch to Control the MOSFET Gate:
- Connect one terminal of a switch (let's call it SW1) to a power supply (e.g., 5V or 12V, whichever is suitable for your setup).
- Connect the other terminal of SW1 to the gate of the MOSFET ($Q1$:GATE). This will allow you to manually turn the MOSFET on and off.
With the MOSFET Driven by the Switch:
- When the switch SW1 is closed, the gate of the MOSFET will receive voltage, turning the MOSFET on, which will energize the relay coil.
- The relay will then switch the load from the NC (normally closed) position to the NO (normally open) position, turning on $LED1$.
Resistors in Circuit:
- Include a pull-down resistor (e.g., 10k ohms) from $Q1$:GATE to ground to ensure the MOSFET is off when the switch is open. This prevents floating gate issues.

Revised Connections:

Switch Control:
- Connect SW1:1 to the power supply (5V or 12V).
- Connect SW1:2 to $Q1$:GATE.
- Connect a pull-down resistor ($R2$) from $Q1$:GATE to ground.
Relay and LED Connections:
- These remain the same as outlined previously.

This setup allows you to control the relay and switch between LEDs by simply toggling the switch, without needing a microcontroller. Let me know if you need further adjustments or have additional questions!
