Switch controller for tower crane

The invention relates to the technical field of building construction, in particular to a switch controller for a tower crane. The technical problem to be solved by the invention is that when the tower crane is controlled by using an operating handle, the movement amplitude of fingers is great, and the switch controller is likely to be operated by mistake, and therefore, safety hazards exist. In order to solve the technical problems, the invention provides the switch controller for the tower crane. The switch controller comprises a controller body, wherein a groove is formed in the middle of the top of the controller body, sliding grooves are formed in two sides of the grooves, blocking covers positioned at the top of the controller body are slidably connected inside the sliding grooves, and a through circular hole is formed in the middle of one side of the bottom of the groove. For the switch controller provided by the invention, a pressing rod can be moved left and right by shiftinga hollow ball, the bottom
