    Hello,

    Show us the schematic how you did connect the things.
    Without the schematic we can not help you.

    What BERTUS said:

    First when you turn it off, if your able, physically remove the switch entirely.

    If it still heats up then your circuit is bypassing the switch somehow.

    Or the switch is shorting the batteries.
