Where is the built in test feature?

Hello Michael, The test lever is on the rear, left side near the wires. Regards, Xylem.

How long are the lead wires

Hello, The wires on all of our Rule float switches are 28" long. Regards, Rule.

I have an older version of this that has a turn able knob on the side. Any idea what this is used for?

Hello, The older float switch has a knob on the side so you can rotate and lift up the float inside to test the system. Regards, Xylem.

Is the hole spacing (and/or general dimensions) the same as on the older mercury switch rule-a-matic plus model?

Hello Matthew, The new float switch is slightly different from the old mercury float switch. The mercury switch has a different hole pattern so you will only be able to use one of the holes from the old switch. Regards, Xylem.
