H-O-A switch?

[x2jearly]

I am using a Photocell with an H-O-A switch to control ten 100w Metal Halide exterior fixtures
at 277v. My problem is where can I get a 20 amp H-O-A switch? Most catalogs do not state
the Amp rating and the ones that do are only 10 amp. Or is there another solution to obtain
the required 3-pos switching? Thanks

You can get standard wall switches in single pole, double throw, center off, maintained contact or you can use a relay
