The famous McClicky made by McGizmo in the USA can take up to 6A current and has a low resistance, it is truly the best switch for any application.
In addition to high current capabilities, the stock Z41 twisty is very difficult to operate a multi-level circuits and drivers. 
The McClicky switch offers a clean forward clicky operation that is momentary on-off capable that has no problem with high current builds.


The retaining ring is made entirely with pure solid Copper for the ultimate performance, this is the best Z41 retaining ring for the McClicky on the market today. 
Brass is only 28% as conductive as Copper. So why settle for a brass retaining ring when you can get a copper one.

The rubber boot is the same one used on our Seraph SP Series Lights. It is our original design that is made to have great durability and rigidness.
