The Klixon M1 precision thermostat is constructed with a snap acting bimetal disc that
serves as the actuating element. As the temperature reaches a predetermined calibration
point the disc snaps to reverse its curvature, producing the crisp, positive switching
action inherent to Klixon thermostats. This feature assures reliable consistent
operating temperature over a longer cycle life.
The M1/11041 series of thermostats are engineered for exceptional vibration and shock resistance to
provide reliable switching in the most demanding applications. Prior to the final weld, finished assemblies are vacuum baked and back–filled with dry nitrogen. The inert, dry atmosphere eliminates moisture and other volatiles to prevent condensation at low temperatures or possible contact contamination at high temperatures. This back–fill also improves the dielectric characteristics of the device and prevents oxidation of the contacts. The M1 thermostat is the ideal choice where quality and reliability are paramount.
All M1 thermostats are supplied with single pole, single throw switching that can be constructed as either normally closed or normally open. The opening and closing temperatures are pre–set and non–adjustable.
