I have a Delta hybrid TS (36-715) and just wired it for 240v. Now the thing

Anyway, in the manual it says to make sure I have a 240v rated switch. The
switch has no rating marked on it so how can I find out if it is ok?

Electrical is more of my practical side:

The Switch (A regular switch that is) is ok if you flip it one way and
the motor starts and if you flip it the other way the motor stops.


False. The switch is ok if that occurs, *and* the switch is rated for both the
voltage and the amperage that it's switching. Better still if the switch
disconnects all of the hot conductors going to the motor.
Must agree with the *and* part.

Here are some symptoms of a under rated switch:
The switch gets hot to the touch
Smoke coming out of the switch
The motor stopped under load and won't start again.


If any of those things happen, wouldn't you say the switch was *not* "ok" ?
Yup, in this case *under rated* or *not* would in my understanding
explain that the switch is bad or inadequate.
