These switch lubricating oils are solid-containing lubricants for the treatment of switch blades and switch controls. Even after longer usage, the special chosen solid lubricants do not leave any residues but provide optimum surface wetting. In case of long lubricating interval, special additives provides sufficient lubrication. The lubricating oils can be applied without prior cleaning, they damp mechanical pressures on the switches, therefore offering outstanding protection against wear and guaranteeing unobstructed function.
