Hi All, I replaced my faulty switch (switch for heater + light) point to point and has the following issues: 1) The switch for the light is working fine. 2) The switch for the heater is inverted - the switch normally in a "off" position is now on instead, the power to the heater is working in this inverted position. 3) Compared to my previous casing, there are 2 additional copper points, which I couldn't what to connect to or how to connect these. Hope someone can help advise this. Thanks.
