External switch + mode control
I was pondering whether or not to use the momentary MC switch for the L32 board, so I built an external switch that contains an On/Off power button and a momentary switch for the advanced Mode Control functions.
It's about the size of a Jolly Rancher and can be used on the bars or helmet.
The body of the switch is 6061 T6.
It has a flashlight type power button and a 6mm micro momentary that are recessed to be flush with the lip of the aluminum. The heat shrink forms a diaphragm over the buttons that will protect it from the elements, but when you push on the front half you get on/off...back half is momentary.
There was a bit of confusion elsewhere as to why I used two seperate switches.
I have two sets of wires coming out of the switch. The power button can do a half-tap. The other set of wires goes to the momentary for the "Advanced Functions" on the L33 MC board:
"As a minimum all you need is to connect the power supply to the power input leads. By interrupting the power supply you can switch between 3 predefined levels (100% -> 20% -> 2%). Optional button provides more features (smooth mode switch, low-mode programming, different strobe patterns). If you need two (or more) modules to work in sync, use PWM output/input pads. Probably I had to reserve posts for them too.""the updated firmware features:
- 3 modes (100%, 20%, 2%) switched sequentially by power cutoff (up to 5 sec)
- 2 modes switched by an optional button
- Adjustable low mode (50%-0%)
- Smooth mode change for easy eyes accommodation
- 3 strobe patterns including ISO standard SOS
To adjust the low setting and to switch to strobe you'll need a button.
Single click switches the light between 2 modes, the full throttle and some low.
On the low mode holding the button >2sec enables low mode adjustment. Any value between 50% and zero may be selected.
On the high mode holding the button during >2sec turns it to strobe mode."
This is my switch:
bulkier than yours, but a bit sturdier. Your self-made membrane is a good idea.
