The invention relates to a transmission device and switch equipment employing the same. The transmission device comprises a main shaft, a transmission rod, a transmission component and a guide structure, wherein the transmission component is arranged between the main shaft and the transmission rod and is used for driving the transmission rod to move; the transmission component comprises a swing arm and a reversing force transfer lever; the swing arm is hinged with the main shaft; the reversing force transfer lever is hinged with the swing arm; one end of the reversing force transfer lever is hinged with the transmission rod and the other end is hinged with a guide part; the guide structure and the guide part are guided up and down for movable cooperation; and when the main shaft drives the swing arm to swing, the reversing force transfer lever pulls the transmission rod to move. Due to the cooperative relationship between the guide part and the guide structure, the stress direction of the transmission rod does not change along the length direction of the reversing force transfer lever, and one part of acting force of the reversing force transfer lever on the transmission rod is undertook by the guide part and the guide structure. Therefore, the component force in the motion direction vertical to the transmission rod is reduced, namely the friction force on the transmission rod is reduced; and metal foreign matters are reduced.
