This is an extra switch for your starting lever and an extra cable that will run from the switch to the timer. The cable's standard length is 40 feet. This switch is used with any of our timers in the DTX000 Product line and also is used to start the TURBO.
If you require the cable to have a different length, you must order the $4.00 charge for each cable length you need to be different than the standard length. You may order these changes in the same section of our catalog, under Optional Items, "Change the length of a cable".
