According to page 7 of the user manual:Hi all,
This is the switch I am using:

To control this:

When some stands on the mat. The input selection should switch.
Bouncing of signal from sitch is very interesting.
I would say max latency is under threshold at which it could be perceived.
Thsnks!
I do not think it would switch back if this was done. Would just stay on in 2. The idea is the it also switches when the button is pressed and released.According to page 7 of the user manual:

all you have to do is connect the mat switch across REMOTE IN1 and G or IN2 and G depending on which channel you want to come up when someone steps on the mat.
If you've got channel 1 set up as default, then when someone steps on the mat it'll switch to channel 2 and stay on channel 2 as long as the switch is made.I do not think it would switch back if this was done.

The TS wants to switch to mode 2 when someone is present on the mat. However, when they step off the mat he wants to switch back to mode 1. (or vice versa) Stepping on the mat will switch to mode 2 and will stay in that mode until there's a command to switch back to mode 1.all you have to do is connect the mat switch across REMOTE IN1 and G or IN2 and G depending on which channel you want to come up when someone steps on the mat.
Lol - trust me, I read the manual. A 10 second lag would not be appropriate for the application. It had to switch back instantly - at least that is what we agreed to with the client.If you've got channel 1 set up as default, then when someone steps on the mat it'll switch to channel 2 and stay on channel 2 as long as the switch is made.
Then, when the switch opens because no one's on the mat, it'll switch back to channel 1 in 10 seconds. Try it?
RTFM!
OK, I think I have a handle on the relay problem.Lol - trust me, I read the manual. A 10 second lag would not be appropriate for the application. It had to switch back instantly - at least that is what we agreed to with the client.
In retrospect, it may have been worth the delay to avoid all of this diode silliness.
Instant switch is what they want and have now though.
EM - this was a concern of mine! Figured it would be fine as the installation was only to be used approximately 9 days - maybe 2000 switches for its lifetime.OK, I think I have a handle on the relay problem.
This is a link to Panasonic's CB relay data sheet, those relays being pretty much what you have in your widget:

And here's an excerpt from the data sheet which describes a relay just like yours:
View attachment 127024
Notice that the MINIMUM current the relay's supposed to switch is 1 ampere, and that's because when it's switching lower than that, the plasma that forms when the contacts open isn't strong enough to blast the switching gunk off the contacts and keep them clean. The usual failure mode is that the contact resistance increases over time and eventually gets to the point where the contacts won't switch the load properly. Like allowing the "timeout" your client doesn't like, to happen.
In your application, the currents being switched in REMOTE mode are probably in the low tens of milliamperes, so the solution would be to use a SIGNAL relay designed to switch low currents. Something like this, maybe:

I don't, but I don't know a lot about the switch so I'd go ahead and install one just for peace of mind.EM - this was a concern of mine! Figured it would be fine as the installation was only to be used approximately 9 days - maybe 2000 switches for its lifetime. Do you think the lack of diode is also an issue?
Day after tomorrow, or next week?The situation now is that the unit is across the country in storage, and is to be installed next Thursday.
I wouldn't even want to guess... Remember Murphy's law?I did include an extra relay (same type I had before) to allow for a swap if anything happened similar to what you describe. Think we're good for another 3 days of use on a new relay,
Yup.or would you wore up a replacement with diode and lower current rating with haste, and ship it to them?
Whatever you recommend they do in the short term, I'd work like hell to get a signal relay replacement to them just in case the replacement they have on hand fails.I'm not sure I can get the relay quickly enough! I'm leaning towards just telling them to replace the relay with the unused spare.
Wise man EM - it's next Thursday. I will do my best to put together an alternate relay for shipping on Monday. Will have to be sneaky - my boss will lose it if he finds out! Hopefully I can do it on the cheap.I don't, but I don't know a lot about the switch so I'd go ahead and install one just for peace of mind.
