If you hear a persistent scraping or rattling sound

the SPDT switch is rated for standard pilot duty and motor loads

Using it in other series without verifying the part number can lead to improper electrode spacing

Exceeding this temperature can cause premature failure of the internal seals and solenoid components

making it ideal for units requiring specific low-temperature limit control
