I've got appropriate buttons and caps for my serial LCD keypad panels:http://liudr.wordpress.com/2011/12/03/phi-panel-face-plates/
Thanks BillI actually ordered some tall buttons from little bird electronics to do just this. Tayda are great, but to get them for the weekend I needed to buy locally. This sure has been a learning experience. When getting one of these shields next time I'll know there's some customisation needed to use them in a permanent situation.Cheers, Geoff
Since a simple button only costs a few cents (in US) but a button with the proper plunger (actuator) for a cap costs ten times more (digikey), I would imagine most LCD shields are made with the cheaper ones.
Their purposes are more academic than practical
