Could you go with a proximity switch?

My son has a "olympiad" event called "Robocross". He has to build a
robot that he would control, that drives around, picks up objects, and
delivers them into a jar.

To that end, I designed a system where the robot is on tracks and
drives using two DPDT momentary switches, turning like a tracked
tank.

It works, but I do not like the switches. One, they have a cheap ****
plastic ring/nut to hold them to the enclosure, and sometimes that
ring slips on the threads.

Two, these switches require significant force to switch (and that is
what affects that ring) and they are just not ergonomic. I want to
find switches that are more feather-light and easy to operate with
minimal force.

Has to be:

* DPDT
* Momentary
* Have quick-connect terminals

Any suggestions?
