Breakers are fairly complicated mechanical devices. They usually consist of one spring loaded contact which is latched into position against another contact. When the current flow through, the device exceeds the rated value, a bimetallic strips heats up and bends. By bending it “trips” the latch and the spring pulls the contacts apart.
Breakers can be reset, yet each time they trip, or are thrown when the circuit is in use, some arcing takes place, which damages the contacts. Thus, Breakers should not be used in place of switches unless they are specifically designed for that purpose.
