Using this compact slide switch is easy. First, connect it to your breadboard. Then, you can use the integrated slide switch to control the power MOSFET. You can also connect an external switch or the digital output of a microcontroller to control it. The switch can handle a current of up to 4 A and a voltage from 4.5 V to 40 V. When using it, make sure the voltage is within the specified range to avoid damaging the switch. For maintenance, keep it in a dry and clean place. If it gets dirty, you can gently wipe it with a soft cloth.
