Lenco Marine elastomer keypad by Elite Label

Lenco Marine needed a user interface that controls the positioning of the trim tabs on power boats. The customer only had a vague idea of how it should look but they knew it needed to be durable, sealable, marine-grade and selectively backlit.

We decided to develop the part based on a similar project for Corvette.  The part uses backlit graphics plus LED windows to indicate the port and starboard trim tab positioning.

This is a compression molded clear silicone elastomer part. After molding, it is sprayed with white paint, followed by black.

The graphics are laser etched down to the white; making them visible both in daylight and at night, when they are backlit. Finally, the keypad is top-coated for durability and mounted and sealed. The part includes a window for a light sensor that adjusts backlighting to ambient lighting. 

In the end, we had a great part that has the necessary aesthetics yet was still able to stand up to the tough marine environment.
