A disconnector for use in a switchgear structured to electrically connect between a power source and a load includes a pair of disconnector blades spaced apart by a distance and having a first end structured to selectively receive and form an electrical connection with a busbar contact and a second end structured to electrically couple to the load, and a pair of magnetic plates mechanically connected to inner surfaces of the pair of disconnector blades and structured to bias the pair of disconnector blades toward each other.

Disconnector having additional holding forces

Switch with a fixed set of contacts and a movable set of contacts. The fixed set of contacts comprises at least one pair of fixed contacts arranged a distance apart and each having an auxiliary contact part and a main contact part. The movable set of contacts comprises at least one auxiliary contact element and a main contact element, which, when the switch is closed, are in contact, under mechanical pre-stress, with the surface of the auxiliary contact part and of the main contact part of the pair of fixed contacts and bridge the distance between the free end edges thereof facing one another, the various features being such that when the switch is closed the auxiliary contact element and the main contact element make contact more or less simultaneously with the auxiliary and with the main contact parts of the pair of fixed contacts.

Switch with auxiliary and main contacts

Set of movable contacts for a switch with a set of fixed that comprises at least one pair of a fixed contacts arranged a distance apart, comprising at least one contact element ( ), a holder ( ) therefor and a resilient element ( ). When the switch is in the closed position the contact element ( ) is in contact, under mechanical prestress, with the surface of the pair of fixed contacts and bridges the distance between the free end edges thereof facing one another. The holder body ( ) has a front and rear face running perpendicularly to the direction of movement thereof and side faces ( ) running perpendicularly to said front and rear faces and parallel to the direction of movement. A side face ( ) is provided with a longitudinal recess ( ) continuing to the end faces ( ) of the holder body for accommodating the contact element ( ) in such a way that the ends thereof protrude beyond the two end faces ( ) of the hodler body ( ). The resilient element ( ) mechanically prestresses the contact element ( ) in the longitudinal reces ( ).
