Introducing the ultimate high power tailcap switch for Z41 and FM26XXX hosts.
Designed as a suppliment to the 1450 Lumen P60 Quad drop-in. This switch's capabilities extend well beyond it's originally intended necessity.
The P60 Quad thread is quite longwinded now, so I wanted to make a separate information thread for the FETtie for any questions or comments.
With any Linearly regulated or Direct Drive light, this will give you more current, and more lumens.
With any Buck, Boost, or Buck-Boost regulators, this will reclaim power currently being eaten by your higher resistance switch, and provide longer runtimes.
How does it work?
The FETtie uses a solid state semiconductor, a MOSFET. Essentially a relay, with no moving parts, which is turned on by the clicky switch. The Clicky switch itself only conducts 100 nanoamps, that's 0.0000001A, to activate the semiconductor. This means the clicking mechanism will last nearly forever, as the electrodes will not wear from arcing.
The FETtie uses a small coin battery, 1216 size. You do not need to worry about this battery becoming depleated however. It's like the battery in a watch, it will last for many years. Even being left on, the switch will draw less current from the coin cell than it's self discharge rate
Specifications:
Current - 25A+
Voltage - 12V MAX
0.0034 ohm Rds(on) MOSFET resistance
Beryllium copper spring, Pure silver plated for extra conductivity, 24K gold plated contact area.
Gold plated contacts from the FETtie to host.
Threaded brass body
Panasonic 1216 coin cell included
Here are some graphs comparing it's performance to a McClicky switch with various cells using my 4.2A Quad drop-in. These results would be compounded with higher currents.
I'll update with some pictures soon. These are only available to those on the closed P60 Quad drop-in waiting list at the moment, but they will be available for all shortly.
