When the switch is not "on" there must be something to make the input
pin sense the "off" state.

Typically you would have a resistor from the input pin to positive,
negative, whatever the "off" state is, to always be a pull towards the
off state. Nothing major, just something for the switch to operate
against. 10k to 100k won't get you into any trouble.

Many PICs have the option of builtin pullups, maybe you could use them
instead of resistors if your "off" state is positive. The default is for
them to not be activated, so you will have to configure them before you
will be using your switches, usually you only do it once, near the
beginning of your program.

Cheers,

Bob
