If so, please fill out our form and we will respond quickly. We are considering using the MET M2 series keypad assemblies in an airborne application. I am confused about what the Semi-Custom keypads are and how to order them. The contacts do not make during the test. It is basically to see if the keypad assembly holds together.
Data is unavailable for any other temperature range.
The adhesive we use to bond keycaps to the keypads is GE RTV-108, which is a clear industrial grade silicone adhesive. The RTV takes 24 hours to cure and can be heat cured to speed up the curing process. You may purchase this from an adhesives distributor. The RTV must be applied as a thin bead around the ledge of the pushbutton where the keycap sits. Care must be taken not to let it smudge onto the top of the pushbutton or else it could interfere with the lighting.
