PRECISION THERMOSTAT Gold Contact Selection Guide
● Gold flashing is provided in cases where power and/or current is low. When thermostats are not cycling, oxidization can form on the contacts. In 1 A or higher applications, oxidation films are not an issue since the current load will continuously “clean” the contacts. In switches below 1 A, the current does not provide enough cleaning, and an insulative or non-conductive state occurs which in effect prevents a closed electrical state.
● In lower limit applications, like the examples listed below, gold-flashing creates a surface that provides minimal oxidation.
