Some times my new mod sigeli #8 missfires and then the button gets really warm. Not hot enough to burn but I assume its from bad contact. I already deleted the spring and fitted a solid cylinder of brass where it used to be, and sanded all brass contacts including the pin on the switch. Anyone have any Ideas on fixing this switch issue. I've sanded its contact and it still missfires and heats up. I'm running it with a 1.12 ohm 30g kanthal coil on a aga t2 with stainless rope and a mesh top.
