The battery is connected to the output of the TP4056 module. From there the supply is linked to a significant-side P-Channel MOSFET. By default, the gate of this MOSFET is pulled up for the VBAT stage. When the tiny slide swap is switched to the gate will probably be linked to the ground and also the MOSFET will be turned on. This simple circuitry
