A novel method based on the switching logic to represent power system structural configuration,operating condition and operation activities for expert system applications is developed.

According to the problem of signal route allocation and management in automatic test system,this paper established route model based on the thought of sharing the information with other models and describing routes with logical switches.

This paper takes the multiposition control of single group light for a example,analyzes the inadequacy of the existent multi-position control circuit of mechanical selector switch,and introduces the basic working principle and practical circuit of the multi-position control circuit formed by the electronics logic switch.
