A combined electric appliance is respectively used for controlling the traction condition and the braking condition conversion of the locomotive and the direction change of the forward and reverse directions. It consists of two electric air conditioners, a pneumatic unit, a piston rod and 12 fixed contacts and 6 rollers (moving contacts). The six moving contacts are mounted on the rollers of the roller bracket. In the absence of electricity, the rollers are always 6 or 6 static contacts on the left side, and there is no intermediate position. When one of the electropneumatic valves is energized, the compressed air enters the transmission air cylinder, drives the linkage rod, and the dial roller contacts the corresponding set of (6) static contacts; if the other electropneumatic valve is energized, The roller will be in contact with another set of stationary contacts. A changeover switch has 12 sets of main contacts, 6 of which are opposite to the open or closed state of the other 6 sets.
