D@mn thing broke the threads off the switch body; switch was hanging under dash while threaded portion was still in the dash. The switch lever itself feels broken but it worked enough to get the hatch up and down.
Sooo...where do I get a replacement?

I would check with Formula technical assistance first. They still stock some of the parts for the SR-1 models. Can then be purchased through Robert. 260-724-1412

I broke mine on our 87 272 and got a new one from Eddie Marine part # M-55054 and the rubber boot M-81264 . 272 FORMULA WITH 383'S FOR SALE .

Did it have the screw terminals? Couldn't find a picture on their site.

Ooof...MSRP $57.38 Talked with Robert and of course his price is better. Darryl says they had Carling do something custom but I can't see what that would be; maybe extra stuff inside to maximize vibe/water resistance.
Gotta find a Carling distributor and the non-Formula part number...

The local Boat Owners Warehouse stocked a Cole Hersee switch that seems to work; probably identical to the Eddie Marine pieces.
+1 for an easy fix

Gee, my hatch switch.......nevermind

Actually someone changed mine, it's totally different than the others and lights up
