The present invention comprises a relay control circuit that provides highly efficient and reliable control for devices that perform in demanding applications such as space. Multiple levels of redundant function control are provided by redundant actuators that perform mechanical operations. Each actuator is driven by redundant motors for increased reliability. Motor current sensing is provided to determine arrival of the actuator at mechanical stops, which are located at the full deploy position. Limit switches also sense when the actuators are in the full deploy position. In addition, multiple control signal so are required to initiate certain critical operations. Critical operations also are performed redundantly for increased reliability.

Relay control assembly

A switch panel that can be quickly and easily reconfigured is disclosed. The number, type and location of the switches and indicators on the switch panel can be selected to optimize the switch panel for a particular application. The switches and indicators are plugged into a fixed receptacle board in the switch panel. A wiring board customized for the particular application is inserted into the switch panel to complete the reconfiguration.
