The present invention relates to a low, medium or high voltage two or three position switch, comprising. a shaft (6); a sun cogwheel (5); at least one planetary cogwheel (4); and a cogwheel ring (7): The shaft is fixedly connected to the sun cogwheel such that an axis of the shaft is coaxial with an axis of the sun cogwheel and the shaft and sun cogwheel rotate together. The sun cogwheel comprises a plurality of outward facing teeth. An axis of the cogwheel ring is coaxial with the axis of the sun cogwheel. The cogwheel ring comprises a plurality of inward facing teeth. The at least one planetary cogwheel is located between the sun cogwheel and the cogwheel ring. The at least one planetary cogwheel comprises a plurality of outward facing teeth. Some teeth of the at least one planetary cogwheel are engaged with some teeth of the sun cogwheel and some other teeth of the at least one planetary cogwheel are engaged with some teeth of the cogwheel ring. In a first switching action, a rotation of the at least one planetary cogwheel about the axis of the sun cogwheel in a first rotational direction is configured to rotate the sun cogwheel in the first rotational direction; and the rotation of the shaft associated with the rotation of the sun cogwheel in the first rotational direction is configured to transition the switch from a first switch-state to a second switch-state.
