Product Description

Technical Information:

The MRK Magnetic Switch, equipped with a reed contact, is switched by the approach of a permanent magnet. The contact surrounded by protective gas reliably reports the position of moving parts. In a bistable version, it has a stay-put latching effect and remains in the switching position until a magnet passes in the opposite direction. The type MRK in the classic round construction form can be actuated at the end and at the longitudinal side.
