Combination Pressure Swichgage instru- ment and Built-in Electromagnetic Switch

High and Low Contacts Can Disable Engine’s Ignition Due to Critical Pressure

Magnetic Switch Will Not Allow Engine Restart Due to Flywheel Inertia

Semi-Automatic Low Pressure Override Push Button for Engine Startup

Description

The 45 Series pressure Swichgage instrument incorporates a built-in electromagnetic switch to disable an ignition whenever the gage con- tacts operate.

Flywheel inertia cannot restart the engine since the electromagnetic switch will not allow the ignition to operate until manually reset.

Asemi-automatic lockout push button over- rides the low pressure contact for equipment startup. The lockout automatically disengages when pressure is established allowing the low limit contact to be armed for operation should a low pressure condition occur.

Specifications

Basic Models

45B Series Swichgage instrument

For use with 12-32 VDC battery ignition systems; it includes battery ignition type magnetic switch.

45CD Series Swichgage instrument

For use with (CD) capacitor discharge ignitions; it includes CD ignition type magnetic switch.

45M Series Swichgage instrument

For use with magneto type ignitions; it includes magneto ignition type magnetic switch.

45N Series Swichgage instrument

For specific use with 110 VAC Power Sources; it includes 120 VAC type magnetic switch.

Models are available for conventional magnetos, capacitor discharge (CD) ignitions, 12/32 VDC battery systems, and 120 VAC power sources.
