Broken Power Switch

[JDC]

Hi, I have a Cool-er with pocketbook firmware running on it and love it even more than my kindle or Android pad as a reader.
Problem is that the power switch on top has become very flaky. It is not broken as such but unless you open the case and jiggle it manually you cannot get the device to power up or shut down.
Any ideas if it can be replaced?
I know i can start the thing up using the reset button or a connecting the charging cable but its not a very satisfactory interim fix and I would hate to bin the device which is otherwise working perfectly.
