Hello to the developers,  
I have a problem with the on/off switch of the RobotHat on the PiCar-X. It doesn’t switch anymore.How can I repair it?  
Which poles need to be connected/disconnected so that I can switch the PiCar-X on and off?  
otherwise the battery will discharge too quickly.  
I hope you can send me an answer.  
I bought 9 more for students and I plan to use the Picar-Xs soon… I hope the other models are better.

Are all 9 robot hats experiencing the same issue, or is it just one of them?  
Could you please provide us with a video of the problem?  
If the issue is with the sliding switch, we will send you a replacement robot hat.

Hallo to Sunfounder !!!

Here I am sending you a photo and a short film. The switch only works when it is pressed, not when it is switched. So far we have only built 2 PiCar-X. The second one has the switch installed correctly and works without any problems.  
I would be happy if you could send me a replacement part.  
Best regards from Germany
