An electrical switch wherein a first contact member is movable relative to the switch body between first and second operative positions, and a second contact member is movable relative to the body also between respective first and second operative positions. The second contact member is movable independently of the first contact member and there is provided an arrangement whereby the second contact member is caused to be in a predetermined one of its first and second positions when the first contact member is moved into its second position from its first position. The arrangement ensures that the second contact member is in said one of the positions by moving the second contact member to that position as the first contact member is moved from its first position to its second position, in the event that the second contact member is not already in said one of its positions. |
