2.2 Special versions
For special versions, which are not listed in the order code below 2.1,
these specifications apply accordingly, provided that they correspond to
the standard version.
2.3 Purpose
Pull-wire switches are used to give signals to start machines and to
open or close electrically-driven doors and gates. If the pull-wire is
pulled, the switching function of the pull-wire switch is activated.
Hoist limit switches are used as signal emitters when the wire rope is
relieved and must be pretensioned by something such as a weight.
