Motor multiple switches and circuitry

摘要

This apparatus incorporates an electric motor disconnecting safety switch within the motor's electrical terminal housing. This results in a single, compact device directly mounted to the electric motor body which is used for the safety disconnect as well as the termination point for the incoming power leads and the motor wire taps. The apparatus may be employed as a disconnecting device for single phase and three phase alternating current motors as well as various configurations of direct current motors. The apparatus further includes a simple and economical adapter plate mounting configuration which accommodates the device to a multiplicity of motor frames. This apparatus is used in three embodiments: the first being a rotary tumbler switching device with an external rotary hand operator; the second device being a draw-out disconnecting means; the third device including an integral motor starter which provides both disconnecting and motor controlling functions.
