A haptic button assembly may be used for detecting inputs and providing haptic outputs at an electronic device. The haptic outputs may be provided in response to detected inputs or in response to other conditions at the electronic device. The haptic button assembly may define an input surface along an exterior of the electronic device. Inputs may be provided to the input surface of the haptic button assembly. An input may include a touch input on or along the input surface and/or a force input directed substantially perpendicularly to the input surface. The haptic button assembly may provide a haptic output by moving an input member of the haptic button assembly laterally (e.g., substantially parallel to the input surface).

A modular hybrid transmission that provides for an improved support of the rotor as well as an improved cooling layout for the stator. The modular hybrid transmission has a rotating assembly and a housing assembly. The rotating assembly includes a rotor assembly, a rotor carrier hub that supports the rotor, and an input shaft.
