Unknown Flomatic Switch

Found this in the basement overhead. House is 1975 and oil boiler is a 2001. No AC is installed. A general internet search and Flomatic’s website did not yield results. I usually think of Flomatic as dealing with valves, not switches. The name on the switch is "FLOMATIC LISTED SWITCH FOR HEAT & COOL APP. 694N. I figured one of you guys have encountered this before.

Likely the Emergency Shutoff Switch for the Oil burner.

Thanks. It had a standard Emergency Shutoff also. Perhaps they didn’t remove the old one during remodel.

Never seen one before.

Found it… “FIROMATIC”…
