Basic principles of circuits with contacts

Designed to teach students industrial motor controls by creating the standard circuits to control different types of motors in different schemes

Extremely compact and flexible equipment, with industrial components, is easily expandable as well

Jumper plugs for connecting the boards improve clarity

Stable, angled, screw-in sockets for contactors, relays, and breakers
