Simple on/off power remote button not working

Simple on/off power remote button not working

I have a simple RF on/off remote that controls a power outlet. The remote is starting to not work when the single button is pushed. So I took it apart, and just from pressing the two dome switches I can tell something is wrong and the contact is not being made. Most of the time the contact between the upper and lower part of the dome is not happening. Does anyone know why this is? Can it be fixed or otherwise replaced?
