HST Series Saftey Interlock Switches


Hazardous machines and systems are frequently equipped with safety elements (safety doors) with a locking mechanism to protect the operator. Their function is: - To prevent hazardous machine functions if the safety door is not closed and locked, - To keep the safety door closed and locked until the risk of injury has passed. A general example: A machine has one or more maintenance openings (part-body access) or is accessible through one or more doors (full-body access). On the one hand, it has to be secured that the machine is switched off, before one of these openings or doors can be opened.
