Where can i get some good tailcap switch for C8 and similar lights? Min 2,5A, but rather 3A or more.
DX and similar have only 1,5A
I doubt you will be able to find them (or at least at reasonable price) Switches like KAN-28 (http://www.manafont.com/product_info.php/ultrafire-replacemnet-tailcap-switch-component-5pcsset-p-7451) work just fine with 3A current.
www.cnqualitygoods.com has a couple of switches that would fit.
If looking for a premium forward-clicky, the "McClicky" switch is an excellent choice for around 6 bucks. A search will provide multiple vendors.
I have had good luck with the Romisen forward clicky from www.shiningbeam.com as well.
Solarforce switches have been increasing in quality over the last year. I have harvested switches from SF tailcaps and pushed 9 Amps through them with the only upgrade being a beefier spring.
Good luck, and please report back with your choice.
this is the same switch, which is in the C8 tailcap, it can handle 3-4A
