The signs are normally placed around or next to the emergency-stop button and are made as standard in yellow engraving plastic with black text. The high contrast keeps the marking clear even where there are many other controls and components.

They can carry the text NÖDSTOPP, extra instructions, symbols or other function information.

Size, outer shape and centre hole can be adapted to the button and the mounting. That lets the sign sit cleanly in a machine panel or cabinet door.

Engraved plastic gives a permanent, easy-to-read marking well suited to industrial use.
