X2 Series – 850F-1750F

rod & tube cutawayThe above illustration shows a simplified depiction of the elements key to the function of our X Series switches.

The outer tube expands at a faster rate than the inner rod allowing for movement of one set of a spring & contact assembly towards another set. Setpoint temperature is calibrated by position of the calibration screw which moves the position of the spring & contact assembly opposite of the moving contacts. Electrical circuit configuration is determined by use of insulators. In our MIL connector designs, the terminal screws are replaced with an inner pin and wire assembly that are connected to related terminals on the MIL connector.
