Switch panel fuses

[Tam Lin]

The switch panel on my new to me Hunter looks like this, see photo. I presume that there is a fuse in each push/pull switch. I have had a go at easing the top off the switch but am worried about breaking something. Am I right in thinking that there is a fuse in each switch and is there a knack to opening it?

Could those be over-current circuit breakers?

They look like circuit breakers. Fused panels tend to look like the one in the photo where the switch is separate from the fuse, which is accessed by removing the cover.

That looks very like a circuit breaker. Do you press it once to turn on and again to turn off? A white ring exposed indicates on.
Could it be this one?

If you can unscrew the panel and look for a manufacturer or part number you will know for sure. ETA, Carling and Shurter are common manufacturers.
Alternatively give it a deliberate overload and see if it resets but this is a last resort.

Thanks guys, they do look like the picture andsarkit put up so perhaps they are not fuses after all. I need to spend some time tracing the wiring as some of the systems don’t seem to work and thought that I would start with the most obvious things, fuses. If I use my multimeter across the back of the breaker terminals and I get continuity when they are switched on then I can assume that they are working?

That continuity test will check them. They do have a small (<< 1 ohm) resistance in order to heat up and detect an overload but if you can see any resistance with a normal multimeter they will be faulty. While you have the back open you can check the part numbers if you need to get any replacements or increase the current rating when you add more equipment.
