Putting caps or even somewhat more complex networks in parralel to switches or around switches is a solution when you cannot change the rest of the system. Correct solution for this issue is debouncing logic (be it in HW or SW). But if for your application an SPDT switch costs same as SPST switch, driving an RS flipflop from that works better (less latency) and component-wise is cheaper than deboucing in HW (same amount of logic, less passives).
