New C-H oil immersed magnetic contactor operated by a clapper typemagnet and armature which increases reliability of operation over thesolenoid and plunger type. tacts connect with suitable terminals extending through hightension insulators mounted on the top of the frame. Thearmature is firmly pivoted to the frame, and is connected bya rod to an arm of the shaft carrying the moving Oil tank removed showing contacts and arcing shields. By breaking Ina horizontal plane, the arcs do not damage other parts. The attraction of the armature against the face of the mag-net rotates the shaft and closes the switch, which is normallyheld open by the weight of the moving parts. A good head of oil is maintained over the contacts byproviding a sheet metal tank of ample capacity, and as thecontacts are situated above the operating shaft, they areaway from any sediment which might accumulate in the bot-tom of the tank. The arc is broken at the contacts in a hori-zontal direction and therefore rises to the point of rupturewithout burning other parts. Transit shields prevent arcingacross adjacent poles. This new oil-immersed switch may be arranged to havetwo contactors act as a reversing switch, in which case theyare mounted side by side, so when one switch is closed thenose on the ai-mature interferes with the movement of theaiTnature of the other contactor, thereby preventing t
