The invention discloses a driving mechanism of a contact assembly of a point switch. The driving mechanism comprises a frame body (10), a first driving piece (20), a first elastic piece (30) and a second driving piece (40); the first driving piece is rotatably arranged on the frame body and can rotate between a first triggering position and a second triggering position and drive the contact type contact switch. The first elastic piece enables the first driving piece to rotate towards the first triggering position. The second driving piece is movably arranged on the frame body and connected with the locking block; when the locking block moves towards the retreating position, the second driving piece can drive the first driving piece to rotate from the first triggering position to the secondtriggering position, and when the locking block moves towards the pop-up position, before the locking block reaches the pop-up position, the second driving piece can continuously prop against the first driving piece to keep the first driving piece at the second triggering position. The contact assembly provided by the invention is simple in structure and high in reliability. The invention furtherprovides the contact assembly with the driving mechanism and the point switch.

    转辙机的接点组件的驱动机构,包括一个架体(10)、一个第一驱动件(20)、一个第一弹性件(30)及一个第二驱动件(40)。第一驱动件可转动地设置于架体且能在一个第一触发位置和一个第二触发位置之间转动并驱动触点型接点开关。第一弹性件使第一驱动件朝向第一触发位置转动。第二驱动件可运动地设置于架体并连接锁闭块,在锁闭块向回退位置运动时,第二驱动件能驱动第一驱动件由第一触发位置转动至第二触发位置,在锁闭块向弹出位置运动时,在锁闭块到达弹出位置之前第二驱动件能持续抵靠第一驱动件使其保持在第二触发位置。本发明提供的接点组件,结构简单且可靠性高。本发明还提供了具有上述驱动机构的接点组件及转辙机。
