1. A method for receiving input from a multiple-function momentary switch by providing feedback from a user interface for each function associated with the switch, the method comprising:

  • associating a plurality of alphanumeric input values with a momentary switch, the switch having an inactive state at rest and an active state when pressure is applied, wherein each of the plurality of alphanumeric input values is associated with a different active time duration for the switch and at least two of the plurality of alphanumeric input values are associated with a same alphanumeric text entry mode;

    determining when the switch transitions from the inactive state to the active state;

    in response to determining that the switch transitioned from the inactive state to the active state, monitoring a duration that the switch is in the active state;

    providing at least one of tactile and audible feedback each time the duration matches an active time duration associated with an alphanumeric input value;

    determining when the switch transitions from the active state to the inactive state; and

    in response to determining that the switch transitioned from the active state to the inactive state, selecting as input from the switch the alphanumeric input value associated with the alphanumeric text entry mode and the duration for the last feedback provided.
