FIELD: electricity.
SUBSTANCE: invention relates to a backplane. Said technical result is achieved by the fact that the bypass switch assembly comprises a bypass circuit and a mechanically actuated switch assembly comprising an electrical contact, and drive, electric contact is movable relative to printed circuit board between spaced closed and open positions, wherein electric contact is in contact with at least one of first and second sets of electric leads of bypass circuit and closes bypass signal path when electric contact is in closed position, wherein the electrical contact is spaced apart from and does not touch the at least one of the first and second sets of electrical terminals of the bypass circuit, when electric contact is in open position, drive is connected to electric contact and is able to move together with electric contact, wherein the drive arranged on the first side of the printed circuit board extends from the first side of the printed circuit board to the free end of the drive, wherein the free end is spaced from the printed circuit board, when electric contact is in closed position, at that force applied to free end of drive, when electric contact is in closed position, pressing free end of drive to printed circuit board, also presses electrical contact in direction of open position of electric contact.
EFFECT: technical result is higher efficiency and reliability of bypass switch of backplane.
