Chubb 3G114E mortice deadlock with microswitch 65quid

That had better be a helluva microswitch for 40quid. I'm guessing
I can buy
the cheapie and fit a microswitch to save cash, anyone tried this on Chubb
or any other?

Can you fit a switch in the hole where the bolt goes?

There are some problems with that:
1. The switch will be used as a final setting switch for an alarm. If
it is in
the lock case the switch will only release when the key is used but
if it's in
the bolt pocket it would also release if the door is jemmied.

Why is that a problem? Just curious.

If I configure it in the most basic way, the alarm will be disabled when the
lock is unlocked and the switch is released. If the switch is in the pocket
in the door jamb and the door was jemmied, the switch would release and .
. . . . . disable the alarm :-/. ie break-in disables alarm.

I see, thanks. I'm used to even more basic configurations where opening
the door merely starts a timer and further action is required to disable
the alarm.
