ABSTRACT:
A method of protecting silver contacts in switches for electronic equipment is provided by utilizing a silicone-based grease which is comprised of a polyorganosiloxane base in combination with a thickener such as finely divided silica or a metal soap and an organomercaptan compound represented by R.sup.2 SH wherein R.sup.2 represents a saturated or unsaturated aliphatic hydrocarbon group having 18 to 22 carbon atoms. There may also be optionally included an ester bond-containing organic compound for improved properties when the treated silver contacts have relatively high contact pressure.
