This is the original message by Chris Phillips:

In my version, following John Barnes's suggestion, I put a 100 ohm resistor
in series with the reeds. The devices are very low current, and if you make
a wiring error and connect them to an output or a battery pack, you will
weld them closed! The RCX doesn't expect 0 ohm touch switches and works
pretty well with them.
