Abstract
An electric switch 11 has contacts 12 and 13 which are initially closed by activating means 14. The invention provides urging means 22 to bias the switch against reopening of the contacts during at least an initial period which is useful if the activating means does not operate for long enough for the electric switch to assume its stable closed position. The urging means is responsive to current carried through the contacts. It is possible to provide a plurality of switches responsive to the same urging means, different switches being provided for different electrical circuits and possibly energised from different sources.
