ST1 control lever: for extreme environmental requirements

The requirement of assuring a high permanent IP protection rating (IP56) on the panel top side led to the development of the ST1 control lever. It comes with chrome-plated and / or aluminum alloy cast console. The galvanized or stainless steel handle provides precise control over the sealed shaft. Motion is captured via bevel gears, contacts, potentiometers and encoders. Motion control can be stepped or stepless. Also locking is possible with spring-return or friction brake.

The switches of the ST1 control lever demonstrate their durability and reliability on ships, yachts, oil rigs, or steel mills.
