Install pushbuttons

Insert the first button and tighten the locknut by hand. Then you insert the second button, from here you have to put on the locknut and turn the button instead of the nut, otherwise there is not enough space for finger and locknut. Continue in this way with all further buttons.

The cables can now be connected to the PCB and inserted into the housing. Now solder the cables to the corresponding buttons one after the other. Please check the pin assignment of your buttons carefully! Not all buttons are the same! If you are not sure, test Smartpusher with one button first.
