I have updated my undercabinet lighting that was controlled by an Insteon 2477D to Lighting Division "No Dot" LED.  The LEDs required a 15V non-dimmable transformer.  I have a Qubino Flush Dimmer to control the 0-10V required to dim the LEDs.  My question is, since the 2477S on/off switch is nearly impossible to find, can the 2477D act as an on/off switch at a zero percent ramp?  I don't want to damage anything downstream.  I looked in the 2477D manual to see if there was a way to configure as switch rather than a dimmer but couldn't find anything.

Any insight would be appreciated.

No, currently your best bet would be to use a Zwave on/off switch

Even at fast On and Off with a full On setting, on a dimmer is not a god way to go. There is still a possibility it may not play well with an inductive load. Unless it has an OK for a dimmer ratting. There is also a short time at Zero Crossing where the output is distorted. When turning on between the cycles. Switching from positive and negative.

The on/off module uses a relay to switch the load, the dimmer module uses a triac designed to work with resistive loads.

I’ve likely got a single band switch that was replaced with dual band switch I could sell you (if you’re mesh will support it.)

I’ll look if you’re interested.

Thanks.  I'll keep that in mind if I don't get this working the way I want.

Luckily Smarthome is still up and order history is available.  Apparently I purchased (4) 2477S back in 2015 that I had forgotten about.  Accounted for 3 so there is still one in a drawer somewhere.  

Thanks for the help!

There is a BUNCH of the "S" switches popping up on EBay....
