You're correct Corbin. The schematic graphic in the wiki is exactly the published schematic graphic in the SAE J1772 Spec. The switches I've seen can all be wired either NO or NC when the lever is not pressed. So it all comes down to how you wire the switch.
If you wire it NC it should read 150 ohms. Then when you press down on the lever it becomes NO and reads 480 Ohms Rush www.TucsonEV.com > -----Original Message----- > From: ev-boun...@lists.evdl.org [mailto:ev-boun...@lists.evdl.org] On > Behalf Of corbin dunn > Sent: Wednesday, May 08, 2013 4:23 PM > To: Electric Vehicle Discussion List > Subject: Re: [EVDL] J1772 proximity stuff > > The Wikipedia wiki should be right: > > http://en.wikipedia.org/wiki/SAE_J1772 > > corbin > > On May 7, 2013, at 2:12 PM, Cor van de Water <cwa...@proxim.com> wrote: > > > The advantage of a Wiki (if the author is responsive) that the info > > can be corrected - it appears that has happened now.
