The double-break disconnector consists of one arm which is moved by the central insulator supporting it and closes the circuit on two fixed contacts, each of them placed on one of the two side insulators. There is direct entry banging type and the other one arm, upon completing its movement perpendicularly to the plane of the insulators, rotates around its own longitudinal axis leading to complete engagement and locking of the moving contacts into the fixed ones
