Here are the 3 metal latches, which need to be bend back before you can take the mechanism apart, if you want. Maybe you don't have to, if you manage to glue the new "rubber stop" into position without taking the mechanism apart. I actually had to take it apart twice, as I forgot the first time 'round to re-position the micro-switch, which hangs on the second connector (see below picture with No. 6). I also had that rubber removed, which is missing here in the picture and glued it then back on
