microswitches, which turn the drive motors on and off
and keep the system perfectly aligned. One microswitch
is the operating switch, another one a safety switch,
which shuts the system off in case of a too heavy
doglegging.
In addition to the microswitches an RC-link is mounted,
which compensates voltage peaks to protect the
If a new microswitch (control – or safety switch) has been mounted into
