These temperature switches are designed specifically for applications where high temperature exposure, hermeticity and vibration resistance are required. A snap acting, bi-metal disc, mounted in the tip of the probe, provides fast thermal response and rapid positive contact action when the pre-set temperature is reached.
The probe's body and tube are of all welded, stainless steel construction with glass to metal seals to ensure hermeticity. Switch design and construction provide high vibration and shock resistance. High contact force and the excellent wiping action of the contacts combine to make the probe suitable for light loads of 100 milli amperes or less.
