The XL-10AH is wide voltage versions. This modules can achieve the same function as self-locking switches by lightly touching the switch to turn on and off the power. It can support a load with a maximum switch current of 10A, can support a wide range voltage of 4.5-26V, and the static power consumption in the off state is about 1.3ua. The excellent performance of the module covers the working voltage and operation required for most DC loads. The small size design also does 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.
