AKG TC-140 oil-cooler temperature switch

The AKG TC-140 is a normally open temperature switch for controlling an oil-cooler DC fan through a suitable relay and fuse. It closes on rising temperature at the published 145°F set point and is intended for the drain port of compatible cooler assemblies.

This execution uses deutsch connector, a brass switch body, nylon housing and a 3/4-16 UNF process thread. Its published contact-current limit is 5 A; this is a switch rating, not a fan power rating. The manufacturer recommends relaying and fusing both the temperature switch and fan.

The manufacturer specification explicitly assigns a 145°F set point to TC-140 and TC-140-WL. The 140 in the model name has not been substituted for that published value.

The exact model appears in the specification and installation drawing. The illustration represents the TC series.
