One of the advantages of magnetic starters is the ability to add control stations. These stations may be located at any convenient location and duplicated as required. The maximum number of stations and their location is unlimited for all practical purposes. Stations are built using Normally Closed (STOP) and Normally Open (START) momentary contact switches. These switches must be rated for the control circuit voltage at a minimum. Over-rated switches will work fine. Many manufacturers incorporate both Normally Open (NO) and Normally Closed (NC) contacts in a single switch body. By rewiring the switch you can change it from one to the other. Many manufacturers also provide interchangeable buttons in at least red and green.
The last station must always be provided to complete the circuit. The intermediate stations may be repeated as many times as required. Suitable 3 conductor control wiring is required from the starter to each of the control stations in turn (daisy chained).
