Abstract
An electrical switch includes a casing having a central and two side chambers that are separated from the central chamber by respective partitions. A switching mechanism in each second chamber has fixed and moving contacts and an actuator. A rocker in the central chamber is used to cause the actuators to move the moving contacts into contact with and out of contact from the fixed contacts. There is also included engaging means engaging each actuator to the rocker for movement thereby, which has a circular part that extends across the first and second chambers rotatably snugly through a circular hole in the partition such that partitioning between the central and side chambers is substantially splash, jet or dust proof.
