I have an Aeotec Dual Nano Switch which was originally wired with standard switches. I changed these to momentary press switches, but they just aren’t working and I’m scratching my head.

If I leave the setting as normal switches, the lights turn on when I hold the momentary press switch down and turn off as son as I release it. This is what I’d expect with a momentary press switch but the Aeotec still set for a normal switch.

But when I change the setting to momentary press switches (to match what is now wired) they don’t work at all.

I have numerous Nano Dimmers with momentary press switches that work fine. This is the only dual nano switch I have.

Does anyone have any ideas?

EDIT: Actually one thing was odd with the original wiring. The sparky had one of the switches wired using the “2” terminal instead of the “1” (which was empty). I thought it seemed odd, but did a like-for-like swap and did it the same way. Now I’m wondering if that could be part of the issue?

It was because one of the switches was wired using terminal 2. When I stopped and thought about it it made sense why it would work like that on a regular switch, but not a momentary press switch. It would have just inverted the on/off positions on the regular switch, but since I could switch it on and off via the smarts I never realised this. But duplicating this on a momentary press switch was never going to work.

Anyway, changing it to terminal 1 on the momentary press switch sorted it.

Have you a good source of momentary switches? When I looked before, briefly, they seemed very expensive. I have legrand excel life switch plates.

@phrozenpenguin

I have PDL Iconic stuff throughout the house, so had to get the momentary switches from that range to fit my existing switch plates.

Not overly expensive (but I get a 50% discount off RRP through a relative with a trade account). They were about $7.50 each with the trade discount, so I guess about $15 RRP.
