The SNH Series of Emergency Stop
Pushbuttons from Wieland Electric is
a modular system that can be adapted
to the needs of the machinery
manufacturer. Eight operator
elements can be combined with 12
different contact blocks.Wieland also
supplies a number of assembled
emergency stop pushbuttons for the
most common applications.

For increased safety, the SNH
Series incorporates a contact block
drop-off feature, offering a signal
output should failure occur if the
contact block becomes dislodged due
to vibration. This has an additional
NO contact in series (preinstalled)
to the main contacts.

This opens as soon as the
contact block falls off,
interrupting the safety circuit and
putting the machine into a safe
position. An illuminated Stop Button
also provides enhanced safety for the
machine user.

SNH Pushbuttons are unlocked by
rotation or with the use of a key and
are supplied with or without a
protective collar.
