Double throw safety switch - [1]
UL standards for double throw safety switches stipulate 4000 cycles rating at 100% power. Should be more at partial power. [2]

Must use several SPDT for creating an automated DPDT relay? Ie, with logic, you turn certain contacts on, and certain contacts off.

GE 100A $200 [3]
Eaton 100A
- Amazon $200 [4]
- Double throw $310 HD [5]
$86 - CSA but non-UL? [6]. You can look up the CSA listing here - it is CSA listed as file # 025483_0_000 [7]
UL, home depot - $200 [8]
