The pushbuttons are screwed to the panel by means of a front ring
and prevented from twisting by two screws.
To ensure correct positioning of the pushbuttons we can provide a
positioning insert on request.
The universal terminals of the low-level switching elements permit
them to be mounted on printed circuit boards (PCB). These terminals
are also suitable for dip soldering. For these terminals we can also
supply a plug-in base which, when soldered on to the board, enables
the switch to be plugged in.
