How to wire a 12v momentary switch with led?

12v momentary switch Circuit Configurations

In electrical circuits, how you wire a 12v momentary switch can affect not only the operation of the switch itself but also connected devices. Here, we explain two different circuit configurations for a 12v momentary switch, focusing on LED indicators and device operation.

12v momentary switch draw Graph One: LED Off When Idle, Device Off

In the first setup, the LED light on the push-button switch is off under normal conditions, and the connected device does not operate unless the button is pressed.

Wiring Diagram

  1. Power positive (12V) connects to Button Switch Wire 1
  2. Button Switch Wire 2 connects to LED positive
  3. LED negative connects to Device positive
  4. Device negative connects to Power negative


  1. Under normal conditions, i.e., when the button is not pressed, the circuit remains open. This means no power flows through the LED or the device.
  2. Once the button is pressed, the circuit closes, causing the LED to light up and the device to operate.
  3. It appears that the device and LED are wired in series in this configuration.


  1. This configuration ensures that the device only operates when explicitly turned on.
  2. The LED serves as an indicator that the device is operational.
  3. You must press the button to initiate any activity, which can be an additional safety feature.

12v momentary switch draw Graph two : LED On When Idle, Device Off

In the second setup, the LED light on the 12V push-button switch is on under normal conditions, but the connected device does not operate unless the button is pressed.

Wiring Diagram

  1. Power positive (12V) connects to both Button Switch Wire 1 and LED positive
  2. Button Switch Wire 2 connects to Device positive
  3. Power negative connects to both LED negative and Device negative .

  4. Explanation

  5. In this configuration, the LED remains on as it is directly connected to the power supply.
  6. However, the device remains off under normal conditions as it is only connected via Button Switch Wire 2.
  7. The device and the LED appear to be wired in parallel in this setup.


  1. This configuration allows for constant illumination of the LED, serving as a ready indicator.
  2. Pressing the button completes the circuit for the device, making it operational while the LED stays on.
  3. This setup could consume more energy as the LED is always on.

Both circuit setups are viable options depending on your needs, but they offer different advantages and disadvantages. Knowing how the 12V push-button switch operates in each setup helps you choose the right configuration for your application.
