Shared control

  A shared control is one overloaded with several functions, to enable activating all of them, using the same control.

Function selection

  The function actually activated is determined by one of the modes defining the active scenario.

Example

The function of an On-Off button is determined by the device mode. If the device mode is Off, the button function is to turn it On, and if the mode is On, the button function is to turn it Off.

Risks

  Shared controls are a primary source for mode confusion
