Hewitt Industries. MurCal Products. MurCal's Toolbox. Clearance Sale. Magnetic switches and Tattletale annunciators described in this bulletin are electrically tripped relay type devices. Models are available to operate from battery power, VAC, conventional magnetos and capacitor discharge type ignitions. Energized to run models allow Closed Loop circuitry. Others draw momentary power to trip. Configurations are available for contact make or contact break to cause shutdown.
Some models have both make and break contacts. All 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 the Tattletale version.
Only the Tattletale connected to that function sensor trips causing the reset push button to pop out. Electrically reset models perform the same functions as the manually reset models and are reset by cycling the power supply off and then on. Specific models allow application of power to a shutdown circuit and automatic disconnect of power after a given time delay. See circuit desriptions below. A : Dry contacts normally wired in hot circuit.
