Disconnect and remove the old switch. Reconnect the leads, tighten the nuts, et voila! Less than five minutes, start to finish.
Good product, easy installation.

Simple Repair, Quick Service
My mower wouldn't restart one day. I assumed the battery finally died after 10 years. Then a short while later parts of the switch start falling off the mower. A quick easy trip to E Replacement Parts got a new one ordered and in the way. It took about 2 minutes to replace and I was mowing in style. Great part, Quick Service.

It was pretty straightforward, unhook the quick connectors from the old switch and slide in the new switch and connect the connectors back up and tighten the nut that held it on, pretty easy.
