Auxiliary switches
Auxiliary switches are used to query the switch position (ON – OFF) of the 3KF.
Auxiliary switches can be used with different switching instants (leading/simultaneous).
Simultaneously: Auxiliary switches switch at the same time as the main contacts of the 3KF.
Leading: If the 3KF switches from the ON position to OFF, the auxiliary switches are
switched before the main contacts open.
For sizes 2 to 5, the auxiliary contacts are snapped directly onto the operating mechanism
module of the 3KF. For size 1, microswitches are used that are mounted in the auxiliary
switch modules.
