CONTROL SYSTEM WITH HIDDEN REPROGRAMMING SWITCH

摘要

A commercial microwave oven having a plurality of operator actuable switches each of which is dedicated to activating the microwave oven for a corresponding programmed time period. These operator actuable switches are located on a switchboard, and a front faceplate has graphic keypads indicating where to push to activate the respective switches. Also located on the switchboard are operator actuable switches used to reprogram the time periods, but these reprogramming switches are hidden because they do not have corresponding keypads on the faceplate. Accordingly, access to the reprogramming feature is limited to those who have been appropriately instructed.
