A material for forming contact members of a control switch, which has a structure including a primary layer made of Ni, Co, a Ni alloy or a Co alloy formed on a conductive base, and a surface layer made of Pd or a Pd alloy having a thickness of 0.001 to 0.4 mu m which is formed on the primary layer. Such material exhibits good resistance to corrosion and adhesive wear. A control switch which is made using such material has a high operational reliability and a long service life.
