You know, while reading the thread, trying very hard to not let all the aggravation vibes get to me, and respecting pakalolo's request to NOT carry on, and in light of OF's latest tidbits, I was thinking about how I would design the switches on the Cera, and what would work best for me. (How's that for an overly medicated compound sentence?)
Now I'm not thinking about how hard my desires might be to manufacture, just what would work the best. To my mind, irrespective of whether we're talking about herb or oil or juice, I want the safety switch to be on the bottom, and the "working" switch to be on the top. The bottom safety switch should be a latching on-off switch, NOT a momentary switch, and should be very difficult to accidentally switch on, and relatively easy to deliberately switch on. I'd pay for an illuminated version. The top "working" switch should be usable as both a momentary and a latching on-off switch.
Everyone (herb, oil, or juice) would use the bottom (safety) switch to protect themselves when they're not using the Cera. For travel, pocket, whatever. Push the bottom switch in, the top switch becomes active; leave the bottom switch out (in the off position), no power to the core regardless of the top switch position.
The original design for the "working" switch was like an old fashioned light bulb switch. A push-push switch with the "buttons" extending through the tube a tiny bit. If the design of this switch were such that it was pretty easy to slide the switch back and forth, while at the same time it wasn't loose and wouldn't slide back and forth without a push, it would serve both the momentary users (oil, juice), and the on-without-holding users (herb), perfectly.
I can't see it the other way around. It's much easier to work a top switch while vaping, where your fingers already are, and much more difficult to work a bottom switch, where your fingers aren't. I've never tried a Cera, so I have no idea if the top push-push switch is easy to slide back and forth, but if it is, then it will work as well or better than a momentary switch (which you have to hold down).
Seems to me this is pretty much what TET originally designed, though I don't know how easy/hard it is to work the push-push switch (OF?).
So I'm gonna continue to wait, until all the parts in all their glory have arrived, and things have settled in at TET, before I order. Since TET will replace any "temporary" parts that come with the pre-order Cera's, including swapping out your used batteries, and giving you a new switch, I don't think there's much down side for those of you who have pre-ordered. You'll get to play and enjoy long before I will...
