All Casios that have a sustain pedal facility use a normally-open non-latching footswitch. This has been the case since at least 1981 when I bought my CT-202, and still applies to my recently purchased WK-3000. As far as volume pedals are concerned, the CT-202 used a simple potentiometer wired to a stereo plug, but I couldn't get this configuration to work on a CZ-1; Casio may have changed the way their volume pedals worked in the 5 or so years between these two models.

As I understand it, sustain pedals are just switches, but they can be
normally open or normally closed. I'm not sure which Casios use. I think
Yamaha pedals won't work and Ensoniq ones will, not that it really helps to
know that.

The foot pedals that I've seen are just potentiometers connected between 12
V and ground with a TRS jack, providing a CV output (though this doesn't
indicate anything for the Casio pedals). Some older Yamaha CV pedals
actually have a lightbulb inside, moving the pedal actually moves a tinted
glass thing between the light and a photoresistor (or something like that, I
didn't get a good look). But probably the basic principle of operation is
the same.
