Some wireless switches use the force of flipping the switch itself to power the transmission: kinetic light switches. That means you need to press a bit harder, but there’s no need to replace batteries.

They claim 10+ years. https://levven.com/products/consumer-wireless-switch-control... but I don't have any personal experience.

I know a couple of wireless X-10 switches I used to own lasted for a very long time. I'm not sure I ever replaced the batteries.

I have a similar system in my rented apartment, and there's no issue with batteries after 4 years so far.

I wouldn't choose it. Every ten pushes of the switch, nothing happens, and there's no visible / feelable state of the position of a switch.

The tactile feedback part of the switch is definitely an area we have tagged for improvement.

Batteries last 10 - 15 years with regular usage (30 on/offs a day). They use just a regular button cell battery.

Thanks! That seems pretty reasonable.
