Magnetic switches operate basically as a latching relay, and are available for use with engines or electric motors. For distributor ignition engines, the magnetic switch opens the distributor coil circuit to cause shutdown. For magneto or CD ignitions the magnetic switch grounds the ignition output. Some models can also trip fuel valves instead of or in addition to grounding the ignition. Diesel engines are shut down by either closing off the fuel or air supply. Magnetic switches can make or break circuits for these engines.
Various circuits, time delays, and contact configurations are available to match the power source and mode of operation required for alarm only, alarm before shutdown or shutdown only. For electric motor applications, various magnetic switches are available to operate the motor starter, holding coil directly or in conjunction with the appropriate Murphy Transformer-Relay assembly.
