I decided I'd better carry a spare kill switch magnet cap in case the worst happens at an inopportune time.
$25 for a new one, or fire up the CAD, borrow a mate's 3D printer and bingo.

If anyone cares to print more it is available on Thingiverse:

I tweaked the design a bit so a bootlace fits through the hole, avoiding the tiddly bit of string.
Also included a bead to tighten the lanyard on your wrist.
Common 10 x 5mm disc magnet (approx $1) slips in and just melt the lip to hold it.

I found melting the surfaces of the lanyard and squashing them together made a solid & neat join.

I have made a silicone mold of the magnets. As @zippy mentioned i mold them up with some carbon fiber and attach a bra strap to them. If  you lose or forget yours then you ride with Nancy all day. I need to make a female version with some tighty whitey elastic and we will call it Dirk or Yanni or something. Team WGASA is an equal opportunity organization.
