BMS as switch problem

Hello, I’ve bought this BMS sometime ago:

and put a normal switch in series with the temp switch inorder to use it as an E- switch, it used to work untill now but all of a sudden it doesn’t and the BMS is always on no matter the state of the switch or even if the input is open.

How do I fix it? maybe you can reset the BMS you make it work again?

Thanks for helping.

I have the same problem. how do you fix this?

No idea yes I’m having bad luck playing with mosfet transistors.
