Bought this instead of the Supco ES671 Lid Switch because the  ES247 was available for prime 2 day shipping and it was less money. I didn't care to wait 1 to 2 weeks for the other part. The pins in the connector of the ES247 are flat, where the pins in the ES671 are round. You will need to cut, swap, and solder the connector if you want to use this on a machine that that takes the ES671 switch. Other than the plug/connector, they are the same.
