  • Patent number: 3952176
    Abstract: A multiple pole bushbutton rotary switch has axial as well as rotary travel. A first dimple in the back of the rotor of a stem and rotor assembly is rotatable over a desired number of position indicating detents for selective positioning of the rotor. The stem is then pushable on its axis to make a second dimple located on the opposite surface of the rotor travel into a second detent on a substrate and make electrical contact between the rotor and contact within the second detent which is preferably coupled to circuit conductors on the substrate. An embodiment of the pushbutton rotary switch is particularly useful for controlling a plurality of different time-date setting functions of electronic watches with a single switch mechanism.
