Can I connect the neutral wire ends via a single switch terminal (without a pigtail)?
&quot;Never&quot; is a bit strong.
This is not a plain &quot;screw terminal&quot; where that would be true. This is a &quot;screw and clamp&quot; and appears to be designed to correctly hold 2 wires, so you are good. That extra bit of brass between the screw-head and the back plate is what makes the difference, along with the two grooves to hold wires in place.
