I am looking for a push button switch that turns on when it is pressed down, stays on while it stays depressed and turns off when it is released.
I am running into "momentary pushbutton" switches such as this candidate:
Do switches like this meet my qualifications?
What you are looking for is a push-on/push-off switch NOT a momentary switch. A momentary switch will only be "ON" while depressed.

One of us is confused. I say the referenced switch is what he says he needs.
Yes. Those are called "arcade switches" and as long as you use the C and N.O. terminals it will stay closed as long as held down.
Yours truly, Mr. Klay Anderson, D.A.,Q.B.E.
The one he referenced is single pole double throw, snap action. I would have interpreted that to act like a change of state relay.
Oh wait, I missed the word momentary in the product description. Never mind.
** Absolutely.
The linked example is "microswitch" with changeover contacts and a rather chunky actuator button.
Should be able to handle a fair amount of current and voltage too - long as it is switching AC.

switch specifications usuallyy have the following notoations
ON-(ON)-none and shorting or make before break thus an (ON)-none-ON switch would have 2 positions. One momentary and the other ON.
The notation of poles and throws are also used, thus SPDT is a single pole double throw (two positions).
Shorting switches were used in audio where both adjacent connections are made simultaneously for a brief instant to avoid pops. This is usually used for rotary switches.
Watch switch ratings: The AC and DC ratings can be very different.
What the OP wants is a simple pushbutton switch, like a doorbell switch.
