Quoted from ClarkWGriswold:I was also wondering if trough switches are a plug and play item amongst most pins of the same era....or would you be locked in to finding a specific OEM switch for a 1982 Bally Vector?
Looks like leaf blade switches all over the bottom :

Should be available or something else easily used. All kinds of leaf blade switches available. Worst case scenario you might have to make new screw holes if you need to adapt something.
