I am thoroughly confused. This is the on/off switch for the brake lights? When the pedal is not being stepped on, the switch is open preventing voltage to the lights, also called normally open. When the pedal is stepped on, the switch closes and allows the current to flow through the lights, momentarily closed. In the open state, the resistance is Infinite, in the closed state, the resistance is zero. Shaffer - verify the ohm meter is functioning correctly, test it by itself, leads apart should read infinite, leads touching should read zero. Then test the switch. whatever reading the meter gets by itself, should be the same as with the switch. Some meters have indicators other than infinite, and there may be a few ohm resistance between the leads, ymmv.
