Abstract

The present invention relates to a three-position disconnector switch, comprising: an earthing contact (1), a power out contact (2), a power in contact (3), a piston (4), and a threaded rod (5). A length of the piston is such that in a first switch position an outer surface of a wall of the piston makes an electrical contact between the power out contact and the power in contact. The length of the piston is such that in a second switch position the outer surface of the wall of the piston does not make an electrical contact with either the earthing contact or the power in contact. The length of the piston is such that in a third switch position the outer surface of wall of the piston makes an electrical contact between the earthing contact and the power out contact. The piston comprises an inner threaded section (7) configured to engage with the threaded rod, wherein a length of the inner threaded section is less than the length of the piston. Rotation of the threaded rod is configured to engage with the inner threaded section to move the switch between the different switch positions.
