ABSTRACT:
The present invention employs rotary switches that can be electromechanically set or reset remotely. Typical, although not limiting, is the use of the switch of the present invention by a trainer located remotely from students' STE. Manual operation is still possible. This allows the setting of the rotary switches to an initial position prior to the trainees beginning their testing. This facilitates remote setup and thereby saves the instructor significant time in manually resetting the rotary switches.
