Contact material reference chart classified by load voltage & current
*If the contact is being used in the constant low-level circuit load range, the Au-clad double layer contact type is recommended. If there is a danger of the current being less than 0.5 A, for instance if the contact is being turned on and off, the Au-clad triple layer contact type is recommended.
The diagram above is intended as a reference. Please use the product within the rated voltage and current.
