You can test the OE switch with an ohmmeter (multimeter set to the resistance/continuity scale).

With the switch in the OFF position, there should not be any continuity between the switch body (ground) and any of it's 3 terminals. It is normal though to have a connection between the low & high speed terminals (those are the outermost terminals on the switch).

When you turn the switch to the LOW position, you should then have continuity between the switch body and both the low & high speed terminals.

Turning the switch to the HIGH position should open up the connection to the low speed terminal, leaving only the high speed terminal connected to the switch body. The high speed terminal is the one that's a little farther away from the other 2 and off at a little bit of an angle.

Finally, pushing the washer button should give continuity between the switch body and the WASH terminal (that's the middle terminal).
