Magnetic Switches

Murphy Tattletale annunciators and Magnetic Switches are the nerve centers that translate Swichgage contact operations into decisions and operate the alarm or shutdown device. They are the electrical load carrying devices for the alarm or shutdown device. Tattletales indicate which monitored function failed leading to the alarm or shutdown whereas magnetic switches do not. Magnetic switches operate basically as a latching relay.

Murphy Magnetic Switches and Tattletale 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.
