Differences between US1-40, US1-30 switches?

[123]

I've been monitoring eBay for used UPB switches. Naturally, most are older models and it can be difficult to find documentation for them. Even when you can find docs, it isn't always clear what the differences are between new and old models. I'm hoping the UPB gurus on this forum can help me sort out the differences.

It appears the current crop of SAI switches are US2-40 (dimmer base w/changeble faceplates) and US11-40 (dimmer with single rocker). How do they differ from the older US1-30 or US11-30?

Well, for one the LEDs are different colors. IIRC, the 30 series was green and red, no blue. Also they would have the older firmware with the 750ms delay that some people don't like. Other smaller firmware tweaks in new stuff, but besides that they should act pretty much like the newer ones.

I use both in my house and no negative waf, I just had to pick and choose my LED colors and make sure I couldn't see 2 different ones at the same time.

I have one of the 140's and it only supports single toggle applications. I wanted to put one in a location where I was using a double toggle and was surprised when UPStart didn't give me an option for the double toggle face plate. Love the 300ms delay on the 140's
