Emergency stop pushbuttons

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.
