ABSTRACT:
A silicone rubber composition is prepared by mixing a diorganopolysiloxane which contains 0.1 to 5 weight % of low-molecular-weight organosiloxane with a vapor pressure at 200.degree. C. of at least 10 mm Hg, with at least 90 weight % of a low-molecular-weight organosiloxane with a boiling point not exceeding 250.degree. C. at 760 mm Hg and a curing agent with filler being optional. These silicone rubber compositions are useful for silicone rubber moldings which can be used to in applications involving electrical switch contacts resulting in electrical switch contact conduction free of defects.
