Auto Sleeper branded control panel problem

Hi Team,

Need some help please identifying my 12V control panel.....it is Auto Sleeper branded, with a Plug In Sytems branded water level meter.....the switches have red reset buttons above them, like mini RCD's, their are no fuses on the panel. Has anyone seen these before or advise on the model, I am assuming they are Zig?

My issue is that one of the switches, for the water pump, has locked and will not move...I need to get a replacement, any assistance would be appreciated.

Picture of the control panel below

Thanks
