Hello, need some help :)

[chipster2005]

I've had my Darwin for 2 years...I love the vapor production..problem is the warranty just expired and there is an internal problem with the brass twist switch. I have had it apart and did a thorough cleaning, but the switch wont work consistently, i think the wires going into the switch may have a bad connection. Is this repairable ? can I replace just the rotating switch. I haven't had any luck on the Evolv site. could use some advice and help. TY!
