This is a Cinemeccanica CC4000H console - common as you like in the UK for at least 20 years, being standard kit in Odeon multis, UCIs, etc.
The Off/Auto/Manual switch is indeed rectifier/lamp control. Its function will depend slightly on whether the auto-strike link is present in the Irem (usually) igniter. Off is self explanatory; Manual closes the rectifier contactor, and if the link is present the lamp will strike (press the red Strike button on the lamphouse door otherwise); Auto closes the rectifier contactor when you run the motor - the lamp will strike if the link is present and switch off when the motor stops.
The blue and yellow buttons are the dowser controls; if memory serves (and it's been a while!) yellow is open. My Italian is sketchy (at best!) - I seem to recall that CO-CM relates to the Italian for 'changeover', a nicely archaic term on what is very much a multiplex projector. Note that the dowser closes when the motor is stopped. The dowser on the Vic 5 (which I think is what you have) is relatively flimsy and will warp and then burn through if a big enough lamp is left to shine on it for long enough. There is a more substantial manual dowser on the front of the lamphouse - a pitfall if one had been doing certain types of maintenance in the morning and forgot to reopen it before showtime!
'Relay SIC' is the fire alarm connection, and was often also used for the 'polyester film tension sensor' to stop the show in the event of a wrap-round with poly film. The red button would light up when the relay was activated, and you had to clear the fault and press the button before you could continue.
There were a number of variations of the control panel over the years, from the cosmetic (round buttons rather than square) to the more involved - the CC4000H was certainly contemporary with the old cam type automation, but I think had been superseded by the CC7040H by the time Vector 500 & 1000 automations came along. The version with the the cam automation included a 'pulse' button to advance the auto, for example.
