ABSTRACT:
A depowering apparatus for controlling selection and deselection of devices, such as a pair of torque motors, comprises two channels. Each channel has a normally open switch in series with a normally closed switch connecting a power supply line to the torque motor. A control circuit in each channel closes the normally open switch of that channel and opens the normally closed switch of the other channel in response to a channel select signal so as to ensure that each of the torque motors can be depowered to allow the other to take control.
