Abstract
A touch sensor assembly. The touch sensor assembly may include a housing, at least one touch sensor and a sensor cover. The sensor cover may identify a touch area associated with each touch sensor. The housing may form a water tight cavity for the sensor cover and the touch sensor when coupled to an housing cover. A raised dome may be provided, e.g. on the sensor cover or another element, to provided tactile feed back. LEDs may be provided for illuminating the touch areas and/or sensing ambient light. A controller may control the illumination level of the LEDs in response to sensed ambient light. Adjacent key suppression algorithms are also provided.
