BQ25886: BQ25886 add a switch on charge line

Hi

My customer use BQ25886 to charge 2 lithium battery, charge adapter 5V/3A. They add a switch on charge line.

1. When the switch is disconnected, connect the adapter, then close the switch, the charging current is normal (1.2A);

2. When the switch is closed, connect the adapter, the charging current is 0.1A at this time, the charging is abnormal.

Why add a switch on the charge line the charger is abnormal.

Thanks
