Help with Torch Modes

Will lift for boobs!
Hi guys

I am not sure if there is an electrical engineer or genius here that might be able to assist me with a problem I have.

I have an LED Torch attached to an Airsoft Rifle of mine with a Pressure pad switch.
The LED has 5 modes, and you have to put the torch off and on again to cycle through the modes. You can't set it to 1 mode.

So this is what I want to do. Basically removing it's memory. Making it have just 1 mode, On and Off.
I saw it is possible but could not find a diagram for my exact torch. it should be similar i suspect though.

Would any1 be able to assist if I post pictures of the Torches circuit?

Thanks =D
 
Not an electrical engineer, nor genius, but with the circuit diagram someone might be able to help. A photo of the circuit might not be as useful, unless a significant chip is identifiable, but the brand and model number would be useful as well.
 
occam's razor tells me remove all circuit boardy stuff and hook the power switch directly between the LED and the battery :D

The Board is very clear, will post a photo and draw up a diagram if needed with the model name and number.
Managed to find tutorials for other models. But have not had a chance to open mine up yet and look! Will post everything later today =D

Not necessarily, there are all sorts of tricks like switching power to create a duty cycle.. In other words, the voltage might be stepped down from the battery in order to not blow the LED, if the manufacturer wanted to use a specific battery because its more efficient or they already had it in stock or his brother manufactures the battery and they don't want to make Thanksgiving dinner awkward or because they like the colour or the battery fell off the back of a truck or they got a good deal on it.

hahahaha!

it sound easier to just buy another torch that only has 1 setting then :p

From a few Tutorials that I've watched and read. Some people just soldered on an extra wire between 2 certain points to bypass certain resistors and so on. Another tutorial a guy took a lead pencil and shorted certain parts of the board on purpose by drawing over it. So as soon as I figure out which part do what exactly on mine, then I should be able to do the same with mine!
 
LED 10mm CL-WT 90Kmcd 10-DEG - R 11
470 Ohm resistor = R20 +/-
Battery = Meh, whatever
Switch = R 2.70 to R20
Misc wires = R20
 
Ok, so do you have a multimeter? if so then just hook it up and find the offending modes and bypass it with some wire and neat soldering. Else just solder a wire after the first resistor past the switch to the circuit immediately before the LED light. That should do the trick.

Else post the circuit diagram and I'll have a squizz

That is for a pack of 10 if I recall correctly. I pretty much just copy pasted from my price list

Yeah, that sound's better :D

Although [MENTION=16362]Flex[/MENTION] is in Centurion, he can probably just bum one off the guys at Micro Robotics, if he gets all the other goodies from there. Or he can come and fetch one from me, I've either got one in my office, or at home, or our resident electronic engineer should have some.
[MENTION=16362]Flex[/MENTION]: Seriously, though, it shouldn't be too hard to mod your light, or build some circuitry to make it better/more interesting/pretty colours.
