Lionel 022 Switch problem

New guy here. What the heck is “the frog”? Explaining some of these terms would be expedient to those not as arcane as die hard modelers

Also, the fiber pin placement is enough to confuse us newbies. Outside rail inside rail, V with different placement recommendations.

Could we once and for all get the CORRECT PIN PLACEMENT FOR THE various turnouts ( I still call them switch tracks!) I don’t mean to sound like a complainer but I just want to see these trains go and work them around the yards more than trouble shooting problems.

BTW my question is, what would make my 022 switch vibrate,chatter without changing its direction? Fiber pins are in the inside rail of straight section. Outside rail of the curved
section. I’ve switched controller wires around with no change. Thanks
