Abstract
A switch assembly, a switch assembly control method, a controller, and a base station are disclosed, which relate to the wireless communications field. The switch assembly includes: a mechanical normally open switch (), a movable contact (), and a controller (), where the controller () is connected to a phase shifter () of a remote electrical tilt unit, and the movable contact () is arranged to move with a driving rod () of the phase shifter (); when the movable contact () reaches a specified position, the mechanical normally open switch () is triggered to close. A prior-art problem that interference is caused to a base station signal because an integrated semiconductor chip radio frequency switch is a nonlinear element and a problem that installation is relatively difficult because a volume of a relay switch is relatively large are resolved.
