That depends on what's causing the failures..
If it's high pressure then a relay will do you no good...
If it's internal contacts , then yes, It will reduce a 15 to 20 amp draw through the contacts down to an amp..(your switch will last forever..or until pressure blows it out..)
You Could just install one in hopes that the failures were contacts..as preventive medicene..(never hurts) and see where it goes from there mechanical~wise.
