how to stop a thread in tkinter python

Question

I am working on a project using Tkinter and threads. Th project is kind of a machine to test an electronic product.

The product is inside a box with an open/close sensor. the product is powered by 220 volts

I am using a thread to monitor the state of the sensor so then when the enclosure is opened (if the value = 0 ) I should shutdown the power supply to protect the user, and this is properly working.

However when the box is opened all the test sequence should stop and the result of the test should be FAIL, but this is no happening and the thread which is managing the tests of the product keeps running (the power supply is OFF but tests are still executed)

I have to find a solution so that when the box is opened, the test sequence stops and return to the initial state.

Any help will be greatly appreciated

Thanks
