The control knob on my Cambridge 302 is slightly bent. It rotates OK
but will not "double click" - it sticks when pushed in and has to be
pulled out. Is it safe to try to bend it straight? Any advice on the
best way to do this?

Probably the worst way is to try to bend it back with your thumb.

Two ways I would try:

1. A 6 inch tube (aluminum, brass, steel, strong plastic) that will fit
snugly over the knob (or better yet, take the knob off and straighten
the shaft directly). Slowly force it back into position. This gives
you a mechanical advantage for the bending and allows you to control it
better with a longer moment.

(or)

2. Tap with a small mallet (carefully!)

Don't have a 302 in front of me, so I don't remember how the switch is
mounted. Assuming that it is held to the front cover or bezel with a
nut, The above should work without much danger of ripping it from the
circuit board below. Otherwise, you might have a repair waiting.
