Abstract
A rocker switch with a shaft (30) 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 (25) which extends around the shaft, has front and rear opposite coil end portions (24, 26) with corresponding spring ends (27, 29), and which has a spring middle (28). Arms mounted on the shaft include a first arm (39') engaged with the front spring end and a second arm (39) positioned to engage the spring middle. When the shaft is turned clockwise from the neutral position, the arms turn the first spring end (27) and spring middle (28) clockwise while loading only the rear coil end portion (26). When the shaft turns counterclockwise, the spring middle (28) is prevented from turning by a spring center support (43), so only the front coil portion (24) is loaded.
