homemade handle bar timing system

[Case king]

Yesterday I made a handle bar timing sytem. It only cost $20.00 and works great.
I picked all the parts up from Jaycar.
All it is is a stopwatch with a remote button.
It is fully sealed so no water will get in.
I didnt solder anything inside of the of the stopwatch only outside
The button is a bit sketchy though bit it works.
Any ides on how to improve the start stop button?

I made mine diferently to the wiki
I didn't solder inside the unit (only outside)
I conneted small wire to the start/stop spring and the lap/reset spring under the PCB.
this is because they are joined together on the PCB and I also couldn't solder onto the tab that moves across.

I brought the wires out where the rope was and filled the hole with silicon. the switch is also waterprof. im planing to get a motorbike kill switch to use instead of the big box

I was about to suggest that. Is your switch an on off switch or a momentary switch. As the motor bike kill switch is a momentary.
