Positively driven contacts are used in some switching
elements. These are special switching contacts that are designed to ensure
the switching contacts are always reliably separated. Even if
 contacts are welded together, the connection is opened by the
is a common feature of all safety switching elements that at least
one switching contact is designed as a positively driven contact.
Often two positively driven contacts are employed to increase safety
 using the principle of duplicated design (redundancy). This
dual-channel design ensures that on the failure of one channel or on a
fault in the control circuit (e. g. in the machine wiring), the
interlocking can still be provided with the aid of the second channel.
