Can anyone point me towards a UK source (phone or online) for an
inexpensive cylindrical, enclosed reed switch, N/C, for use in a
burglar alarm circuit please.

I'm still googling but so far without success and want to place an
order for delivery Monday.

No Radio Shack there? Try an alarm company then... They were commonly
used in the big dish satellite systems on the positioning motor, but
since big dishes are uncommon now, that's not a good source, but some
satellite dish companies may have a few sitting on the shelf.
