ABSTRACT:
A multi-function switch assembly is provided for mounting to the end of a tubular member. The switch assembly provides control information to external devices via control wires contained within within the tubular member. The switch assembly includes a housing defining at least one internal cavity for mounting switch components therein, and also defining an internal bore configured to receive the tubular member. The internal bore communicates with the internal cavity, allowing the control wires to enter the housing. First, second, and third switches are mounted within the internal cavity defined by the housing. A rotating switch actuator actuates the first and second switches which are positioned such that when the rotating actuator is rotated in a first angular direction, the first switch is actuated, and when the first rotating actuator is rotated in a second opposite angular direction, the second switch is actuated. A linear switch actuator actuates the third switch. The first, second, and third switches are electrically connected to output generating circuitry which generates an output signal from which the open or closed state of each contact can be determined.
