Description
What it is
Power signal indicator with 22 mm switch button, suitable for monitoring the power status of an electronic circuit.
Features
- Dimensions: 22 mm
- Operating voltage: 12-24 V
- Button type: non-locking switch
- Available colors: Red, Green, Blue, Yellow
What it is for
This power signal button is ideal for monitoring the power supply of an electronic circuit. It is useful for Arduino projects, 3D printers, and security systems. It can be used to create a power monitoring system for a 3D printer by connecting it to the circuit and using an Arduino to send notifications when the voltage is low.
