The use of single-pole, double-throw switches with the split pattern blade, spring connected,not only permits making better contacts and greater ease inmanipulation, but also a quick snap break. although they are expensive, delicate in contact adjustmentand liable to burn out. The knife-blade type of automatic mag-netic circuit breakers with broad, ample final break on car-bon, has proven its trustworthiness, low firstcost and correspondingly lower maintenanceand operating cost. The writer is familiarwith one case alone where the difference infirst cost of the circuit breaker was 6o per centin the prices of the laminated and blade types. Another interesting application of circuitbreakers is the employment of two breakersconnected in multiple instead of one,
