ABSTRACT:
An electrical switch (20) comprises a plastic base (40), a plurality of base terminals (102-112) mounted in the base, a manually pivotable actuator (200) supported for pivotal movement relative to the base, and at least one actuator terminal (260) mounted to the actuator. The actuator (200) is pivotable between a neutral position in which the actuator terminal (260) is in contact with one (106) of the base terminals (102-112) and at least one actuated position in which the actuator terminal is in contact with another (110) of the base terminals. The actuator terminal (260), when the actuator (200) is pivoted from the neutral position to the at least one actuated position, slides out of contact with the one (106) of the base terminals (102-116) and slides into contact with the other (110) of the base terminals. The sliding movement of the actuator terminal (260) into and out of contact with the one (106) of the base terminals (102-112) and the other (110) of the base terminals cleans the actuator terminal and the base terminals to help prevent contamination.
