I took the switch apart and the wire became undone from the switch. The are 4 colored wires to be reconnected. Orange/grey/red/black. The terminals are as follows.

T1 L


T2 T3

The arrows are clock wise from L to T1.
I may have to replace the switch. Where do I buy one.
Any help will be greatly appreciated. Thanks

Is this switch for a fan?

Are you here in the U.S.A. The switches seem to be 250V switches. If so you can very seriously injure yourself if there is a 250 volt feed.
