A rocker switch is provided with a mechanical switch unit comprising a switch housing 11 in which a spring-loaded reciprocating switching element 14 is mounted, and an actuating rocker 16, connected to the switching element 14 and with an electric Hall sensor switch unit 17. A rocker switch of this type is composed of few components, requires no mechanical adjustment for the central position or for the end stops and therefore achieves precise resetting and operates without play over its entire lifetime. The switching element 14 comprises a hinge pin 30 rotatably mounted in the switch housing 11 and surrounded by a doubled coiled spring 25 biased in the switch housing, one of two free end legs 27, 29 of the spring being fixed in the switch housing 11 and the other being mounted on a first arm 38 non-rotatably connected to the hinge pin 30. The central spring leg 28 is mounted in the switch housing 11 and also on a second arm 37 non-rotatably connected to the hinge pin 30. |
