Please verify SPST means 2 terminals on back of body.

SPST means single-pole, single-throw. This switch has 3 terminals: cold, wiper, hot.
Actually, he is asking about the switch portion, not the potentiometer portion. SPST does mean there are two terminals on back of body for the switch portion; it is a simple on-off switch.

Correct, the two lugs on the bottom of this pot are for the SPST portion.

Is the switch detent-type (i.e.when the shaft is turned fully counter-clockwise it clicks off) or push-pull type?

Do you have a pot like this one with a tap. I need one for an old Crosley radio. SKU: R-VS-XA
Item ID: 003904
I would assume the tap as at the 500k point.
Thanks and God bless,
Glenn

We do not carry any tapped potentiometers at this time.

Suppose I use this as power for my amp, if I use the pot as volume, too--wont it be noisy?
(I can't find a rotary switch.. which is what I need for my old radio conversion to guitar amp. long shaft to get through the cabinet.)

There are many factors that contribute to excess noise, but using this as a power switch and volume knob is the most common application for this item, and it shouldn't add any excessive noise.

Do you have a pot exactly like this (500K + rotary switch) but with a plastic (insulated) shaft? thanks.

Great item. Thanks.
This potentiometer works very well for antique radio restoration and the price is right! Very easy to file a D slot into the shaft. Fits the knob perfectly. Thanks much!
Worked perfectly in my old, trusty MSA volume pedal. Easy to install and quiet, great sweep, and true; highly recommended.
AES is my go to spot for vintage radio parts. They have the best prices, quality, shipping and service. This part is no exception. It goes in a 1946 RCA 66X1, now it sounds great.
It is hard to find a potentiometer with a long shaft. A long shaft can be shortened and modified to fit, but a shaft too short requires more work. Electrical performance seems to be just as good as original.
Perfect fit in my S-20R.
Very good parts and a good price
Buy them as long as they are available!
Excellent quality product. Well-packed and prompt delivery.
Excellent products. No problems at all.
