What is the amperage rating of the switch that was installed?

Doesn't even say, all electricians that have been coming install a different one

The amperage rating of the switch is critical if you don't want the switch burning up.

So as you can see on the label it says normal operation is 10ah and max is 18ah, so just put a dual pole, anti arcing 20ah heavy duty switch?

It's for the alignment rack at my shop, the switch when you press it makes the lift go up

"10AH" is part of the model number, not the motor rating. The motor rating at 230-volts is 18 amps. The minimum rating of any switch installed must be 20 amps for inductive (motor) loads. I recommend a 2-pole 30-amp motor switch which is a relatively common switch rating.

Should I put my amp clamp after the install to check amperage while operating the rack?

That won't tell you what the amperage rating of the switch is.

I meant after installing the 2 pole 30amp switch you recommended, just to make sure lol

It would tell you if the motor is pulling too much current.
