Review on REIFENG Mechanical Endstop Switch Arduino by Sam Sergio

Pros: The click is clear and sounds good. On-site PCB quality soldering is top notch. Cons: I had to put a small dab of CA on the red button on some of these to get them to work. I would definitely buy them again, for the price plus the presence of the included cables it's a bargain and the problem is not showing the cork. The problem appears to be in the metal lever itself. If I activated the hand, it would "kink" where the red button is and wouldn't activate, but if I lightly press the area above the button with my index finger while the hand is activated, it would click . This leads me to believe it might be the arm itself as it bends too easily.
