New product alert
I like checking out new amp building products that come out.
One new item that CEDist/AES listed as a new product is the round hole speaker impedance switch.
I ordered some so we'll see how I like them compared to $10 3P switch I normally use and either include the 4/8/16 ohm indicators on a panel or label maker or mojotone round panel they sell.

Re: New product alert
Interesting switch. I'm curious about the chassis hole size? Please let us know. Lifetime 300 operating cycles seems kinda short, but maybe not.

What is the current rating?

Re: New product alert
What prevents it from rotating? D-shaped mounting hole? I agree 300 cycles seems like limited life... six years if you switch it once per week.

Re: New product alert
It's plastic, I'm guessing they don't expect you to be switching impedances tons. In most cases, the life of a specific amp is set for a cab until sold to someone else who may have a different cab, and switches again. I do agree it's not a long lifespan, but likely due to the cost being lower than the nicer clunking metal ones.

Re: New product alert
Maybe the thing to do is to buy one for use and one or two more for spares.

Bogner uses these switches. Mouser carries them, I had ordered one a few years back. Schurter 0033.4032 hidden under voltage selector switches.
Re: New product alert
I could be wrong but on page 2 of the diagram, doesn't it show a notch on the bottom?martin manning wrote: ↑Fri Sep 07, 2018 5:02 pm What prevents it from rotating? D-shaped mounting hole? I agree 300 cycles seems like limited life... six years if you switch it once per week.
Not sure if the hole is 22mm or 20.3mm
Re: New product alert
It looks like the diameter is 20.3; the notch adds ~2 mm.
Does anyone have a bit or punch for 20.3 mm?

Re: New product alert
Of course, everyone who drills holes in a chassis for mounting a switch, jack, etc. has a T-handle reamer to enlarge holes.pompeiisneaks wrote: ↑Sun Sep 09, 2018 3:11 am looks like almost exactly .8 inches another random size.

Re: New product alert
oh my, you're my hero, my stepper bit is often a royal PITA, I do have some punches that fit standard holes for my larger stuff like sockets and cap cans, but that thing looks outanding, I'll have to get me one.

Re: New product alert
I solved all my hole size problem by ordering metric step bits and don't use my reamer.

Re: New product alert
Looks about 13/16 inch. Might be able to find a hole punch. I like M Fowler's big metric step drill idea too. It's hell to open up a hole with a Dremel grinder, done way too many octal socket holes that way, also the large rotary impedance switches. Add an hour to the job and a lot of hand pain. For those lucky enough to have a big drill press or milling machine, good on yez!pompeiisneaks wrote: ↑Sun Sep 09, 2018 3:11 am looks like almost exactly .8 inches another random size.

down technical blind alleys . . .
Re: New product alert
Received my new switches.
The outer ring is 24.55mm
There is a small bump on threaded part for locking this into place. I measure this to be 22.23mm
The threaded part is 19.80mm or 0.7805 inch so drill the hole that size and file a V notch on the opposite side of the 8 ohm indicator.
I measured this using a cheap Pittsburgh digital caliper.
I have not drilled hole or installed this impedance switch yet.
