ABSTRACT:
An electrical slide switch comprising spring-action mechanics (5) overcomes the problems of fused contacts (3,6) caused by high starting currents by the provision of disconnecting mechanics (2,9) which positively separate the rocking arm (3) from its associated contact (6) as the switch is turned off. Preferably the disconnecting mechanics does not act on the rocking arm until shortly before the switch-off end position of the slide switch is reached. The disconnecting mechanics preferably consists of an insulating material lever (9) which is pivoted by a pin (11) of the slide member (2) against the force of a spring arm (22), the insulating material lever (9) having a lug (12) which protrudes into the path of pivoting movement of the rocking arm to positively move the same.
