Ilford DT600 timer hopes and wishes

Hello all.
I'm looking for any ideas about how to connect a foot switch to my cute little Ilford DT600 timer. The timer and power pack are in perfect condition; just hoping to add the luxury of a foot switch. It's a luxury that I'm generally used to, so I can't go back. Good for dodging and burning, little burps of light....

I have searched far and wide and have never seen a reference to an actual foot switch, just comments such as "and you can plug a foot switch into the little holes"...
I've looked for small 2-pin connectors that could hook up to and split from my mini-jack switch; no luck so far.
The holes are 1.8-2mm, set apart exactly 10mm centre to centre.

Anyone know of any foot switch availability? Any MacGyver connector hack for my existing mini-jack switch?
Thanks!

KHB makes them for the 400 and 500 series controllers. Perhaps they have knowledge about the 600 series controller.
The connector for the 400 series controller - which was the one I was familiar with - were a particularly UK sort of connector.
