After I received the switches then I find out I have to use finger to hit the center part of the switch to activate it. For my application I prefer to use hand to push the switch instead of finger. My application is to pass signal to VFD controller. I may have to take the silver bezel off in order for me to operate it with my hand. I also saw the features of this modular switch on UTUBE. It is quite interesting.
Perfect seller and perfect items,thanks_
