Circuit Playground Jewelry?

[SamLH]

I'm teaching an intro class to older women students and am thinking that using a circuit playground to make a wearable broach would be ideal. I think I could use the sticky back magnetic bars to attach it to clothing and then use velcro to attach a small lipo battery to the back of the circuit playground also.

The problem is in designing a good on/off switch. The JST lipo extension switch is really too big. I was wondering if I could simply cut the power side of a small lipo battery and solder in a lilypad on/off switch? (This switch is rated to about 350 mA) (Sorry, I know that adafruit doesn't sell these kind of inline small switches, but I couldn't find anything similar from Adafruit).

Thanks, Any help or suggestions would be appreciated.
