The XL-10AL module can achieve the same function as the self-locking switch by touching the switch, so as to turn the power on and off. It can support loads with a maximum switching current of 10A, and can support operation at a voltage of 3.5-5V, and the static power consumption in the off state is about 300na. The excellent performance of the module covers the operating voltage and operation required by most DC loads. The small size design not take up too much space on your device. For the button part, if you want to use other styles of buttons, you can also connect other styles of touch buttons to our switch control board through wires.
