ABSTRACT:
The front panel of a control panel is provided with a recess for receiving a keypad. The recess is larger than the keypad to define a channel between the edges of the keypad and the sides of the recess. A sealant fills the channel to provide a smooth transition between the front panel and the keypad that protects the edges of the keypad and prevents the entry of moisture and debris into the channel. The control panel can be assembled by fixing the keypad within the recess, placing a temporary barrier over the top surface of the channel, and introducing the sealant into the channel. The sealant can be introduced through one or more ports in either the front panel or the temporary barrier. The temporary barrier is removed when the sealant hardens within the channel.
