Electronic help request.

Hi There,

I will repairing two ultrasabers, due a lack of saber smiths in hong kong.
Now i want to setup my stunt sabers in this order:

re-purpose the 6W LED units from Ultrasabers.
Completely rewire the lot, by using a single 3.7 LIPO battery holder: http://www.thecustomsabershop.com/18...lder-P886.aspx
Install a simple click switch: http://www.thecustomsabershop.com/Pu...utton-P40.aspx.

Place the battery holder in a PVC Tube that runs from pommel to the free floating LED unit from US, so the LED unit cannot move down inside the hilt upon vertical impact.
I slide a bit of the PVC pipe out of the hilt bottom upon unscrewing the pommel to access the rechargeble 3.7 battery and off on switch.

The reason for this is, i keep breaking the standard plastic guarded latching switch: http://www.thecustomsabershop.com/SP...tton-P255.aspx

I do alot of spinning and my sabers often fall on the ground hitting the guarded section resulting in shattered plastic. I tried my best to find a more durable solution, but it seems the only option i have are momentairy switches which require a switching board. http://www.thecustomsabershop.com/16...itch-P714.aspx

I do not care about the LED light on these switches i only care they are made of alloy vs plastic, i understood that both the 12 and 16 mm do not fit in the milled standard hole by US anyway.

So my question is what would be the best possible way for me to create a very simple electronic design and have a durable switch button? my sabers get a serious amount of beating. I am no saber smith and don`t have alot of tools such as dremmels etc so thats why i mainly got the option to go for a PCV pipe chassis.

I hope you can help me out with this one, thanks!

Measure the switch you have and search online for a replacement, otherwise you'll have to find the means to resize your switch hole. Momentary-to-latching boards aren't difficult to find. I believe there is one in the TCSS store.

Thank you sir, i will measure it up. Lastly for a 3.7 18650 battery with a US 6Watt LED what resistor should i use and should i place the resistor close to the LED or close to the battery holder? int he TCSS youtube channel i could find the how to build a lightsaber, but i could not really understand why i should put the resistor close to the battery or LED.

Thanks!
