Abstract
A switch mechanism is provided for inclusion in a downhole production string located in a wellbore. The switch mechanism includes an electrical power input and at least two electrical power outputs. In addition, the switch mechanism includes an actuator mechanism which is capable of being actuated from a position remote from the wellbore to selectively move between at least two positions. The movement thereby provides a selective electrical connection between the input and one of the outputs when the actuator is in one of the at least two positions.
