4 Buttons 

In membrane 

keyboard

3 LEDs - light pipes with domes 

which protrude up and out of the 

enclosure wall and are heavily 

frosted — key point is to get the 

LED light up and out of the 

enclosure so it’s more visible in 

bright sunlight.

Membrane 

button panel is 

sealed and water 

proof

Notes 

Buttons have a “clicky” , responsive tactile feel 
(to enable multi-click commands) 

Membrane is UV stable, sealed and water proof 

LED light pipes are embedded  in enclosure 
wall adjacent to membrane keypad — these 
light pipes do not run through the membrane 
itself
