I guess bridge....like a switch between 2 two channel amps

If you have two stereo amplifiers and one pair of speakers, then no.
If you have two stereo amplifiers and two pair of speakers, then yes.
If you have two stereo amplifiers that are bridgeable to mono and one pair of speakers, then yes.
Got any pics of the amps front and rear?

The amplifiers, if using two together for stereo, on the same pair of speakers. Need to be the same model amplifier..
Use only if a Mono amp, or one's in bridge mode. One amplifier one speaker....
If wanting to use them on the same pair of speakers.
Never connect two amplifiers up to the same speaker(s) at the same time. One stereo amplifier at a time.

1) Wanting to hook up both amplifiers to both speakers at the same time?
2) Wanting to hook one amplifier to one speaker and the second amplifier to the second speaker?
If 1, then no. If 2, then yes.2) Wanting to hook one amplifier to one speaker and the second amplifier to the second speaker?
Adding on to what @Natertots mentioned, I would also clarify what it is you have, as of 2020 based on your Profile Post you have the following:
Kenwood kr7600, Kenwood kd2070, Kenwood km106, DBX CX3 MkII, HPM 100, KEF k series
The KR7600 is a Stereo receiver
The KM106 is a Power amplifier
I think that maybe OP does not understand what the term "bridging means". Because from what he said it appears that he wants to hook two amps up to one set of speakers and then be able to switch back and forth between them.
@jorgdelnorte... is that correct?

Please provide the use case. What are you trying to achieve? That will help people understand your question better.
I use two amps in my system driving one pair of speakers, but the speakers are specifically designed to allow biwiring. One amp drives the woofers, and the other drives the mids and tweeters. It's kinda dumb, actually, because the speaker crossovers are still in use, so I'm not really gaining anything by using two amps (though I'm not losing anything, either). But I had the amps so I used them. I used to drive two pairs of speakers from two amps, until I replaced the speakers and rearranged my music room.
You cannot wire the output of two amps into one speaker input.
If you a setup that allows you to compare amps, then you have to switch both the inputs and outputs to and from the amp together, so that the amp that is not in use is electrically isolated from the system on both inputs and outputs. The preamp you mentioned works only on the input side.

What if he used an input switch box in between the preamp and amps? Use it backwards so there is one input and two separate outputs. Would that work?
I am still confused at to exactly what OP is trying to achieve so I am guessing. Also I am assuming there is no control over the preamp outs, that they are not selectable in any way. Hence the input switch box used in reverse.
And then I suppose one would also need a speaker selector switch also used in reverse. That would isolate the output from one amp form the output from the other.
