I installed 3 smart switches which are all on the same circuit in my house. I have never changed a light switch before, but I followed the directions very closely and watched a couple of Youtube videos to help me understand the different wires in the gang boxes. All the switches seem to be working (2 single pole switches and 1 3-way switch -- I haven't replaced the other 3-way switch). All of the switches have a light on the button. When I put my non-contact voltage tester near any of the switches, it beeps. Is this normal? Safe?
Edit: To be clear, the voltage tester doesn't respond to any of the other switches in my house, but of course those don't have lights or use the neutral wire.
