Device for indicating the position of a valve spindle

A device for indicating a position of a valve spindle of a valve, the device comprising:

• the valve spindle and a spindle extension which are moveable between a first position and a second position;
• first and second markings arranged on the spindle extension so as to be spaced in the direction of motion of the valve spindle;
• a sensor module comprising first and second detectors arranged on a printed circuit board and respectively associated with the first and second markings such that the first detector is configured to detect the first position when the first marking lies opposite thereto and the second detector is configured to detect the second position when the second marking lies opposite thereto;
• at least a first optical display element configured to indicate the first position, and a second optical display element configured to indicate the second position, wherein a first end position indication is assigned to the first optical display element and a second end position indication is assigned to the second optical display element;
• and
• a cup-shaped housing module secured to the valve, wherein the valve spindle is movably guided in the cup-shaped housing module;
• wherein the sensor module and the first and second optical display elements are arranged within the cup-shaped housing module, and
• wherein the cup-shaped housing module comprises an end face provided with a partially transparent protuberance configured such that an end of the valve spindle projects into the partially transparent protuberance and is visible through the partially transparent protuberance when the valve spindle is in at least one of the first and second positions.
