Abstract
A control housing is provided which encases a control board. The housing has a cover and a backing which are fixed together to secure the control board within the housing. The control board includes a plurality of switches, and the housing includes a plurality of corresponding buttons to activate the switches. The cover includes a cover surface having at least one button hole in register with the control board switch; operating insignia integrally formed on the cover surface adjacent the button hole; and a membrane which closes said button hole to form a button surface. The insignia is exposed through the membrane to be exposed and visible. The membrane is fused to the cover, thereby providing a housing which is sealed to substantially prevent gases, liquids or solids from entering the housing.
