The original switch would have been a brass/porcelain combo, I believe. The bakelite ones were replacement as far as I know. My 102 has the bakelite housing as well, with a standard bakelite light switch, and an original would have been brass.

Thanks.
Mine has a brass housing with a bakelite "finger" almost flush with the housing. I figured there would have been a larger knob or something to make it easier to work with the foot. If anyone else has a good photo, I would love to see it.
Here are some more hoover styles. The one on the left is off of my friends 1908 spangler suction sweeper, the predecessor to the Hoover model 0,
The right image is the switch on my 102, this is a common replacement switch for these. They work well, and are not as dangerous as the originals could be (no exposed metal in case of shock.
Hi Brandon. At last count, I have about two 541's and one 543. They all have the same switch which may be brass under the bright plating. Attached are some additional photos. As you can see in the last photo, even the Hoover Baby has the same switch. Hope this helps.

Attached is a photo of another 541. This one is a dog and was hiding in my shed but I accepted it when it was offered. One second thought, the base metal of the switch cover may not be non-ferrous brass due to the appearance of some rust

Brandon - attached is a photo a Hoover of the same time period "Hoover Baby" model 103 (c.1921). It features the identical power switch set-up. Hope this will be helpful in some way. Thanks for asking.

WOW! Thanks Bernie. That was very informative. I have seen both I think. My friend who has the spangler suction sweeper also has a Baby model C from the early teens thats all original. I wonder what kind of housing it has. Ill have to ask him.
You're welcome, Brandon - anytime. I've been on this earth for a while - don't know it all - but sometimes I might be able to help. ;-) Feel free to call. Thanks,
