Reason: Quality image of a mercury switch. Good depiction and complements the lead sentence of the article: "... an electrical switch that opens and closes a circuit when a small amount of the liquid metal mercury connects metal electrodes to close the circuit."

Oppose - Would be better without the background, size already mentioned in caption. There also are some droplets (not mercury) on/in the glass, looks like contamination. Here's a pristine example, as I'm used to see them: [[1]] --Janke | Talk 19:52, 7 May 2023 (UTC)[reply]

I deduced the size from the background. I am pretty sure the contamination is from the de-plating (wicking) of the electrodes. It shows the switch has been used. Bammesk (talk) 20:57, 7 May 2023 (UTC)[reply]

Support It could be sharper, and is a bit grainy, but presuming that's normal for objects of this size, we're good. Adam Cuerden ^(talk)_{Has about 8.3% of all FPs. Currently celebrating his 600^th FP!} 23:55, 8 May 2023 (UTC)[reply]

Oppose per Janke. At fuller resolution the background isn't as distracting, but at thumbnail size it makes it hard to concentrate on the subject of this photograph. — Chris Woodrich (talk) 12:01, 13 May 2023 (UTC)[reply]
Even worse, IMO, is that it is a damaged specimen - I didn't really state this clearly in my oppose above... --Janke | Talk 07:27, 14 May 2023 (UTC)[reply]

It isn't a damaged specimen. It is used. Bammesk (talk) 12:51, 14 May 2023 (UTC)[reply]

The ones that I have owned didn't look like this even after being used... --Janke | Talk 19:24, 14 May 2023 (UTC)[reply]

Ok but that doesn't mean the nominated specimen is damaged. It is just used. Electricity, materials, operating conditions, etc .... lots of factors. Not all apples are red! so to speak! Bammesk (talk) 00:21, 15 May 2023 (UTC)[reply]
