Thanks for reaching out to Tundra Restaurant Supply with your question Ron.
The face of the Cecilware L155A Lighted Rocker Switch measures 1"W x 1 1/4"H. That said, I've actually tracked down the replacement On/Off switch for your EL-6 Electric Fryer. The appropriate replacement piece for your fryer is Cecilware part # 08054.
We do not currently stock this part, but we special order for customers on a daily basis. If you'll give a member of our team a call at 1-888-388-6372 we'll be happy to order the part for you.
