Your light switch is a few wires (is it dual-controlled).

Since you need to press the reset button, it is a leakage.

If you have the conditions, find an electrician to use a shake meter to measure the insulation of the line to the ground, I doubt that your switch controls the zero line.

When the switch is turned on, basically the zero sequence current transformer of the leakage protector does not detect the abnormality, so it does not trip.

When the switch (let's say it's the control neutral wire) is closed, the zero line from the switch to the lamp is disconnected and grounded, and the live wire is grounded through the lamp, so it will trip.

You can try to see if your light can't be turned off without a leakage protector You can also reverse the zero fire wire to see if it jumps when the light is turned on this time, which basically means that my judgment should be right (of course, it is best to use a meter).

If you suspect that there is something missing, check the wiring between the main switch and the front of the light switch.

Under normal circumstances, there is no problem with the lighting circuit, the lamp is the load.

After the lighting switch is turned off, there is a virtual connection place in front of the lighting switch, and the grounding resistance is small, resulting in leakage tripping.

Hello Upstairs said pretty much the same, if you can't figure it out yourself, it is recommended that you look for the property and ask a professional to take a look.
