Why is it called a stand by switch?

I am too lazy to turn a knob, pushing a switch seems much easier.

Whether you call it a Stand-By or Standby or whatever the switch has a purpose in a tube amplifier. It switches the B+ (B-Plus) voltage on and off. This voltage is applied to the plates of the tubes so they amplify. When you flip the POWER switch on you should have the Standby switch in the Standby position and only after the tubes have had a chance to warm up (a minute or two) should you apply B+ to the tubes. Use Standby while you're on a break at a gig to be kind to your 6L6 or 6V6 output tubes. Throwing B+ on the plate of a cold tube actually abuses the tube...trust me.

On older tube amps there was a polarity switch to make sure the amp was grounded to the correct side of the A/C line. Generally you could hear a "sizzle" sound out of the amp if the polarity wasn't right. This problem went away when polarized (3-prong) power plugs became standard. Before that amps has 2-prong plugs that could be plugged into a wall socket or extension either way. I learned that if I didn't have the polarity right I could get one hell of a shock off the microphone or if I touched a bandmate's guitar strings and we were not at the same ground potential. ISYN

I have two amps with a Standby switch.

My Blackstar 5 watt has an incredibly useful Standby. With power on and standby off I can run a line into my PC and record in silence, using the PC speakers to keep a low volume ear on the process. It means I can record any time of night without annoying my spouse. I only care about her nocturnal irritation on the grounds that she lives close enough to hurt me in my sleep.

My Laney VC30 (90s model I think) is kinda temperamental. The manual (which I didn't read for years) warns that all volume/gain controls must be set to 0 before the Power and Standby switches are turned on. It doesn't say why. But if this isn't done the amp blows a fuse. I turn ALL the knobs to zero now and wait a good 1 second before going from Power on to Standby on. Mildly annoying, but the thing has such fabulous tone and deafening volume I won't replace it.

Cold tubes don't conduct.
Throwing B+ on the plates of a cold tube does nothing.

I use it because Bogner basically made it just too easy/convenient not to engage it - yet another reason the Bogner Shiva 20th is one of the best amps available today (and my personal favorite that I own) - it’s one switch (as opposed to 2 separate switches like most amps with a stand by option) - the up position is off, middle is stand by, and down is on/play - not sure why every tube amp isn’t built this way to be honest.

I'm almost done my first beer and will soon need to order a second beer. I suppose the last 2" in the glass means I'm on standby. But first I'll go stand by the entrance for a smoke.

The stand by switch is simply a spare Power Switch.

Kinda like the extra buttons you get sewed to the inside of your shirt.

And just as useful.
A Side Bar...

ever notice that the shirt manufacturers who provided extra buttons
sewn into the shirt AND yet never got used?

It was only the cheap shit shirts that never gave you extra button(s) and
it seems like I always had a button fall off.

. . . and after four washings, they don't tuck in properly anymore.

I turn the volume control down to switch guitars. Can't hear the pops then.
I usually pull the cord from the amp side, and it doesn’t pop. Just enough to disconnect the tip, then pull the cord from the guitar. No need to adjust the volume.

though not a tube amp, the Kemper pops when I do that, but none of the tube amps do :dunno:

that's all well and fine, but some volume controls can be a little tricky to set blindly. my 2204 goes from Zero to Murder in an almost imperceptible distance on the volume knob. (the MV is worse than the preamp, but still....)for just switching guitars i'd probably just mute with the tuner if i have my board. if i'm plugged straight in, i just yank it out real fast and plug the other one in as smoothly as it'll go.
but people can do it however they like.

You know that boat won't float.... There will be screaming, crying, pulling hair out, gnashing of teeth, self flagellation, PMs to all the Top Men 24/7, goodbye threads from hell, more goodbye threads from hell, I'm really leaving this time threads from hell, and then it'll get real bad...... Never underestimate the dumbassery of the poochie lipped....

Well, to put a positive spin on all that; the wig makers, hair replacement people, dentists,
TOP Men specialists will be working and the economy should become robust as feck.

Just call me "Sunshine".

How about just turning on your tuner when you go to switch guitars or take a break? That's what I do, easy.
