Brake pressure switch leaking

In the process of replacing the master cylinder on my 88 GXL, while bench bleeding the MC, I notice fluid leaking out around the pressure switch, so I replace the crush washer and go back to bleeding. Few seconds later fluid starts flowing out around the wires on the pressure switch. Called Mazda, they have nothing but a part number fb0743410 that is NLA. Local parts stores are at a loss. Dealer suggested I try the internet. Has anyone ever had this issue?

The switch for the ABS on the bottom you are referring to? Try some teflon tape on the threads.

Car doesn't have ABS.
Also, the fluid I thought was running out the bottom turned out to be coming from the brake fitting on the far side that I couldn't see. Cleaned it up and all is good now. Minus the caliper hardline threads being cross threaded . . .
