Rockwell 315 circular saw switch

[Bruce]

Need a replacement switch for my circular saw. Does anyone know of a replacement for that original switch, number 843156 (or 876341?), or a source for it?

The OEM switch is probably unobtainium excepting, perhaps, finding a scrap similar saw on eBay or the like.

However, the local Ace hardware has a nice selection of replacement tool switches; on can generally find one close enough to make work. I'd think most places would have somesuch similar.

Sometimes, one can disassemble and repair the existing one if it's just a spring or other mechanical failure.

I no longer have the URL but several years ago I order switches for my shop vac at Mouser Electronics - Electronic Components Distributor.

I suspect they are still in business and can be found buy a search.

I believe this is where I ordered the parts.

Even with shipping which as a percentage of the materials order was quite hight it was cheaper than buying a new sweeper or using a jury rigged system for the rest of its life.

You mean something like this source?

Nevermind...Just read the legend. Obsolete, Unavailable.

As penance, I'll offer this:

Lot's of parts for $100:

Which is clearly marked as Obsolete, no replacement available.

Not that one can't often find something close enough online but might as well look for local options first.

Took less than a minute, did you actually look for the part ??

Which I clearly pointed out 5 minutes later *and* offered an alternative as penance.

What do you have to offer?

[Scott Lurndal]

And of course everyone's newsreader sees all articles at the same time, and reads them in reverse order. Duh. Do you understand how Usenet works?

One of these:

I believe that saw was originally made by Porter Cable. As such, perhaps a search under that name that might turn up parts otherwise missed...

[John McGaw]

Probably this will work under the Porter Cable nameplate:

Again, have you just gone to the local good hardware store and looked through their selection? There are those long rows of yellow (typically) assortment boxes of all kinds of odds and ends there for precisely this reason.

Here's a link that shows just a few random replacement switches...

w/ one specific that would likely be workable.

Then again, keep looking at more recent P-C saws until find one that is still available..

says it's a replacement for one of those numbers you gave earlier.

In the end, "a switch is just a switch"; there's nothing magic about the part number specifically, you just need one that has minimum current rating for the use and that will mechanically adapt to the location.

That's a pretty ordinary form factor it appears from the parts figure.

IOW, don't make it harder than it needs be...
