does a Vacuum Time Lag Switch in reverse exist ?

TPTB appreciates that the PestStop device we have is discouraging the local cats & foxes from wrecking our garden but its presence unsettles her.

The compromise we have reached is for me to fit a button which she can push which will disable it for an hour or so at a time.

I can't find such a device - does it exist? I could make something with a relay I guess as the power source is ultimately DC but a mains switch would be more believable. Something looking similar to this would be ideal:

in other words it can be wired as "normally closed"

You'll need to go to an electronic timer likely for that sort of time. This would probably do what you want:-

Vellerman probably do something - Maplin stock most of their kits.

RS do loads of DIN rail mounting multi purpose timers that cover most eventualities.

for example:

Doesn't really need to be, does it ? If it switches the 'wrong' way, then just reverse the action by using the switch to control a relay with c/o contacts. Then pick the n/o or n/c contacts to switch your load ...

What a disappointment. I was hoping someone would come up with a switch that turned on for an hour *before* you pushed the button.

A bit of creative thinking could let you only push the button if the horse won and place the bet only if the lamp lit an hour earlier :-)
