Abstract
A rocker switch with a shaft ( ) that can be pivoted clockwise or counterclockwise from a neutral position, which reliably returns to the same neutral position without “play”, and which is of simple design. A coil spring ( ) which extends around the shaft, has front and rear opposite coil end portions ( ) with corresponding spring ends ( ), and which has a spring middle ( ). Arms mounted on the shaft include a first arm ( ) engaged with the front spring end and a second arm ( ) positioned to engage the spring middle. When the shaft is turned clockwise from the neutral position, the arms turn the first spring end ( ) and spring middle ( ) clockwise while loading only the rear coil end portion ( ). When the shaft turns counterclockwise, the spring middle ( ) is prevented from turning by a spring center support ( ), so only the front coil portion ( ) is loaded.
