(ET) power disconnect switch

[David Brandt <ev_dave13 yahoo com>]

Would these be appropriate for a main disconnect?  It isn't clear what the 
duration of "intermittent" and "crank" is, but if the first isn't enough 
there is always the "Heavy Duty."  I like the feature of being able to 
remove the knob, thus locking out the tractor.
