ABSTRACT:
A sealed toggle switch is formed of a hollow thermosetting plastic base, a metal cover closing off the base, a rocking blade, and a bat actuator handle having a ball disposed to rotate in a socket bushing in the cover and a resiliently biased finger pushing against the blade to rock it from one position to another when the bat actuator is moved. Sealing is accomplished by an O-ring seated in a groove on an upper surface of the base and extending around the periphery of the same. This O-ring is compressed by the cover to form a seal. Another O-ring is seated in an annular groove in the bushing and is compressed against the ball of the actuator handle. Contacts of the switch are selectively connectable by rocking of the blade, and these extend through the base. Seals, such as O-rings or flat rubber seals, are provided between these contacts and the base. The toggle switch of this invention can favorably be constructed as a single-pole, double-throw two-position switch or a single-pole, double-throw, center-off three-position switch.
