ABSTRACT:
A portable teaching apparatus comprises interlock cancellation switches and at least one operating switch for producing a signal which remains effective only when the interlock cancellation switch is depressed. A box-like body with the operating switch arranged on the front surface thereof include two parallel strips of apexes on the back side thereof. Slopes which steadily approach the front side and continued from the apexes are formed between the two strips of apexes. The operating buttons of the interlock cancellation switches are mounted on the slopes respectively.
