I used this switch on mine. It was an exact copy of the switch I had installed some 30 years earlier except this one was rated for 30 amps and the older one was rated for 15 amps. You can use this or one just like it (available at places other than Amazon) to replace the original switch...but please note: this is a 4 position switch...acc/off/on/start If you're using a foot start, you will just need to wire for acc/on/off.
