BLF Ti: Update the switch

PayPal the same as the one we sent the light money to?

Rey what’s your PayPal? I know it’s listed elsewhere but might as well put it in the op here too.

Count me in for one upgrade switch Please!

Rey, I will wait until you mention when and how to make the Paypal payment! for this part.
I don’t want to jump to conclusions.

Just received my BLF Ti yesterday in the mail. Very pleasant surprise!

Thanks!

2 set for me, thanks.

I don’t suppose it’s possible to get just the ring?

Any idea if other hosts might come with a compatible ring? I have some Convoy S-series lights where I only use the head (for firmware testing), and could use the tail parts in other lights.

The Convoy S series seems to have slightly differing threads from the BLF Ti, except for the S7. Not everybody is having trouble with the switches. All of mine are fine, albeit with the weaknesses noted above. And the more competent replacement from Rey is only $2.50.

FWIW I tried both the S2 and S7 rings in the Reylight. Both are much too large in diameter.

Good thought though. Something out there other than the original X6 probably fits.

Sorry, paypal will be updated in OP.

Payment sent for two switches. Thanks.

My Light’s been delivered and kudos, Rey. Nice job. I see the issue with the switch. Can you put me down for one? Also, mine came without the rubber button, do you have any the right size?

I have one of the first batch BLF EE X6 and the retainer and switch fit nicely and should work fine as long as there’s a proper sized disc over the switch for the rubber button to seal to.

You can probably find something suitable in the hardware store, but weird enough Fasttech sells them as a dedicated switch part : https://www.fasttech.com/products/1616/10007333/1611614-iron-tail-switch-gaskets-for-led-flashlight-diy . I ordered them a while ago to see if they fit the small Omten correctly (they should) but they did not show up yet.

PayPal set for 2 sets

Switches arrived, kinda bad news. Some of them doesn't match. Threads are smaller.

Due to the tiny machining difference. Really tiny.

I tested 2 Ti tails, one inner size 17.9mm, the other 17.93mm.

Retainer in 17.9,works fine.(a little loose though)

in 17.93, after pushing the button several times, retainer crooked and fell out.

I'm thinking to machine some retainers. Maybe in aluminium, I did not see any brass or copper material in factory.

That is quite a setback, sorry to hear that. Brass is nice but aluminium retainers should be fine too if they are a bit thicker: because of the softer material the threads wear out easier. I think 3mm thickness is thick enough for good threading and thin enough to not cause extra battery space problems (a compressed tail spring will not normally be thinner than 3mm).

Yes I agree. Note the threads in the tailcap inside interfere with the battery (18mm battery ) so even if the ring is thick it should work.

I guess that I’m in for 1, maybe 2.
