Power Seat Switch Interchange

My '59 retractable has power seats. However, the seat trim was removed and thrown around carelessly (prior to my owning the car) which broke the switch to pieces. I can find Thunderbird seat switches fairly easily. Are they interchangeable? For that matter, which years interchange with a '59 power seat switch?

Update: Terry Miller at Jerry's Classic Cars had a switch. Maybe that info will help others.

Update: A power seat switch from a 59 Mercury worked too.
