A switch for use in a pole for situating an electrical fixture remote from a base position is described. The pole is moveable between an operating position and a maintenance position, and the switch may automatically connect/disconnect power to the electrical fixture based on the position of the pole. The switch comprises a sensor for measuring an orientation of the switch, a microcontroller for processing the orientation of the switch as measured by the sensor and providing a microcontroller output signal based on the processing of the orientation of the switch, and a controllable switch for connecting and disconnecting the electrical fixture to and from a power source based on the microcontroller output signal.
