I just got my Protege back today after switch replacement. I took one puff on it and it wouldn't shut off. Luckily I was paying attention and didn't burn up the atty. I immediatly took battery out and took the switch out. The switch didn't seem "stuck". It clicks when pushed and seems to be working fine. Put switch back in and it stayed on again after releasing the button (I'm not real sure but don't think it was on until I pushed the button). Again took apart and all seemed ok. This time when I put it together it wouldn't work at all. Messed with it some more, checked button again but this time I pushed the center post out on the part the atty screws to and when I started to put the atomizer I heard the sizzle that tells me it's working, only I'm not pushing the button. I guess the question is, do you think it's the switch, which is new today, or is there something that I'm doing or that I need to check before I start a ticket for a new switch, again. BTW this is similar to the problem I had when I sent in for first switch. Thanks in advance for any help.
