Need help finding a switch

I had a PCB made up and wasn't careful to pay attention to the pin
spacing on the switch I used. I need a SPST momentary switch with a 4mm
or .156" pin spacing where the center pin is common. I wanted it to be
..1" spacing but I didn't double check that so now it is too late. I
have been looking at data sheets for switches from mouser and digikey
and have had no luck yet. I am thinking I may have to get out the
drill, and drill some new holes.

Drill it if you wish to save your PCB....

A SPST switch doesnt usually have a center contact, just two end ones.
Did you mean SPDT?

I've seen a SPST that used the same construction as the SPDT. These had
a center pin and one side pin only.

Seems like _everybody_ has switches with contacts on 0.185" centers,
so if you use a rat-tail jeweler's file you'd only have to elongate
the end holes by about 0.030" each to get them to fit.

Is it possible to mount the switch to the intended enclosure and wire
down to the board?
