This example describes the multi-place control switch, you can turn on or off any partial load(electrical equipment) of the working power source. The switch can be used for corridor, public areas lighting control. It can also be used for industrial production (more than one place on the factory floor control of a set of production equipment). The multi-place control switch circuit consists of intermediate relays KA1 ~ KA3 and S1 ~ Sn. It is shown as picture. If you need to control the power of a larger load, you can use AC contactor to replace KA1. Components selection: S1~Sn selects moving together (normally open) buttons. KA1 ~ KA3 select 220V AC relays.
