One level Clicky Switch fits the Aleph and Surefire E Series. Like the Kroll and SF Z57, it provides momentary on or latched constant on. In its planned form of application in a tail cap, lock out is available by twisting the cap loose from the battery tube.
On the Alephs, leave out jamnut and screw in McClicky2 inside the rubber boot, just like the original McClicky. It screws into all the Aleph tailcaps.
When used with a GDuP driver or GDuP light engine with a single cell battery, it turns the single stage clicky light into a 3-level light.

The McClicky2 replaces the McClicky which is the same switch with the addition of two holes drilled on top.
The McClicky2 works on the Alpeh lights and McClickie pak.
