Can flip the In and Out on the Brake light switch?

I am using a single caliper setup from a late 70's kz something or other on my 78 kz200.

I am using this setup to replace my UNOBTAINALBE cable actuated setup found on the kz200's


I was able to modify everything to get it to fit on the bike but in order for the brake light switch to fit correctly I need to reverse the lines and mount the switch Upside down.

I am wondering if it would still even function like that?

What do you guys think?

If it is a two wire switch, it should make no difference which way the two wires are connected.

I Should have stated I want to actually swap the hydraulic lines and not the wiring.

Am thinking a pressure operated brake switch may be fitted anywhere into the brake line whereby squeezing the hand brake lever will pressurize the brake fluid inside the line and thereby activate the switch.

The electrical connections are designed to complete the brake light circuit when the switch receives pressure from the fluid inside the brake line.

In brief, the pressure turns the switch ON, and releasing the pressure turns the switch OFF.

When the brake isn't being applied (handlebar lever not being squeezed), there should be no pressure in the line. (The tiny orifice at bottom of master cylinder is designed to release the pressure inside the line when the handlebar lever is released. The larger orifice supplies fluid to the bore.)

Good Luck! :)

I can't see how it could make any difference. The switch is "piggybacking" along a pressure line to the caliper. Regardless of which line goes to the master cylinder, the net pressure is the same on the switch.
