You're trying to boost a backlight? If the LED is fed through a resistor as usual, just put a switch + resistor in parallel with the existing one so that the LED current increases when the switch is on.

plenty of switches here:

That's beautiful, Catskull, thank you.  Want it to add a small button on the front of a GBC to boost the brightness of an AGS-101 screen mod using BennVenn ribbon connector and SP AGS-101 driver board - not because it's necessary, just because it would be fun.  smile

Any reason you can't just use a "normally on" switch?

Does anyone have an easy hack or knowledge of a small pc board to enable using a momentary switch to send a constant signal? (on/off)

I've found this:  http://www.instructables.com/id/Use-a-M … shbutton-/  but am hoping someone has a ready (and very small) alternative.
