I purchased a 10-pack of the new blue switches, and literally on the 10th one, I have an odd issue (the other 9 work great!).
This switch is installed in a simple on-off, power->switch->light configuration. When the switch is off, there is no issue. When I turn the switch on, the switch itself seems to emit a ~7600Hz whine (as measured by my phone). It is very quiet, but unfortunately this switch sits right above the sofa, so there is usually a head right nearby to hear it, and boy does it get annoying after more than 10 seconds of it.
The switch is hooked up to one of these: https://www.amazon.com/gp/product/B08ZN6BV43
Things I have tried:
- Putting it into dimmer mode (the whine didn’t go away, but the pitch did change as it dimmed)
- Swapping it out for an old red switch that I have (that worked, so this is a regression compared to the red switches)
Things I have not tried:
- Swapping the switch out for another blue (this was literally the last switch I had to install, so swapping would require unwiring a switch from somewhere else. I’ll likely try tomorrow though if there isn’t a solution by then).
- Swapping the light out (it is hard to reach and is an integrated unit rather than one that has bulbs).
Curious if anyone else has ran into this or if anyone knows of a possible solution. Thanks!
