  Magnetic Switches /
® Annunciators


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



Multi purpose TATTLETALE®:
Featuring dry contacts that can be used to make two circuits and break another when tripped. The operating coil is intermittent duty and must be disconnected by an external circuit when tripped.
