Hi All,
My understanding is that when building a power on switch for a large heating element (30A), a low voltage switch is used along with a 30A contactor.
I was wondering if there are any drawbacks to using these:

it's what i currently use on my 20A controller. I am converting to 240/30 and would like to simply add 1 more block to my switch rather than getting an extra component (not a lot of space in the box).
Any reason a contactor is a better solution?
thanks
