Console with grounded trim ring
A vehicle console includes a trim ring disposed over a periphery of a housing. The trim ring includes a polymeric material and is electrically conductive and grounded. A proximity switch assembly is retained in the housing. The proximity switch assembly includes a proximity sensor proximate a sensing pad for generating an activation field. The sensing pad is proximate the trim ring.
1. A vehicle console comprising:
a trim ring disposed over a periphery of a housing, wherein the trim ring comprises a polymeric material and is electrically conductive and grounded; and
a proximity switch assembly retained in the housing, comprising:
a proximity sensor proximate a sensing pad for generating an activation field,
wherein the sensing pad is proximate the trim ring.
2. The vehicle console of claim 1 , further comprising:
a lamp, wherein the proximity switch assembly is provided on the lamp, wherein the housing comprises a bezel with an aperture, and wherein the sensing pad comprises a lens disposed in the aperture.
3. The vehicle console of claim 1 , wherein the proximity sensor is a capacitive sensor.
4. The vehicle console of claim 1 , wherein the trim ring encircles the sensing pad.
5. The vehicle console of claim 1 , wherein the trim ring is electrically coupled to a conductive support and wherein the conductive support is electrically coupled to a printed circuit board (PCB).
6. The vehicle console of claim 5 , wherein the trim ring comprises a heat stake pin that is connected to the conductive support.
7. The vehicle console of claim 6 , wherein the housing is a first polymeric material and the trim ring is a second polymeric material.
