25700287 518PH-12 12V Magnetic Switch Compatible with Murphy Switchgage for Bandit Chipper Marine Diesel Engine Heavy Duty Generator 10A 14A Fuse Current

Replacement for part numbers：25700287, 518PH-12, 518PH12Annunciators and magnetic switches are the nerve centers that translate contact operations into decisions and operate the alarm or shutdown device.They are the electrical load carrying devices for the alarm or shutdown device.Annunciators indicate which monitored function failed leading to the alarm or shutdown whereas magnetic switches do not.Magnetic switches operate basically as a latching relay.Magnetic switches and annunciators are available for use with engines or electric motors. 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 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 and annunciators can make or break circuits for these enginesAll models have a weather-resistant case with screw terminals for ease of customer hookup. Manually reset models have a face mounted reset push button which also serves as a fault indicator.In this application, one or more magnetic switches are used to advise operating personnel which monitored function caused shutdown.Features：Covered with a weather-resistant case with screw terminals for ease of customer hookupAlso designed with a manual indicating reset type which also serves as a fault indicatorHas a control circuit output contact that is NCH and NOH.In the latched position, the NCH contact has a “hot” output; in the tripped position, the NOH contact has a “hot” output, latch type which is energized to latch.Note:1.This Magnetic Switch is not original parts, the mention of brand names and any related model designation above is only for purposes of demonstrating compatibility.2.NO installation instruction and recommend professional installation.
