ABSTRACT:
An apparatus is provided for coupling a control device, which is adapted to rotate, to a stationary switch which is adapted to energize and control a machine. The coupling is made through a rotatable swivel which connects a freely rotatable table to a stationary support. The control device is mounted on the table and the switch is mounted on the stationary support. A ring is coupled to the control means and moves up and down in response to the control means. The ring is further coupled to the table and freely swivels and turns with the table. A U-shaped bracket is connected to the switch means and alternately contacts both the upper and lower surfaces of the ring as the ring moves up and down. The stationary switch means is thus switched from the first position to a second position providing a mechanism to control the machine from a rotating table without control hoses or cables becoming tangled and twisted.
