Smarthome Insteon Switchlinc V2 Dimmer The INSTEON SwitchLinc Dimmer is so easy to install and set up, and yet so affordable, you'll want to replace all your switches with SwitchLinc Dimmers. Just remove the old switch, reattach the line, load, and ground wires with the addition of the neutral wire using the included wire nuts, and you're done. For the ultimate in personalization, the SwitchLinc Dimmer is available with a custom-etched paddle. Ideal for labeling switches in a multi-gang setup, custom etching allows you to identify at a glance which switch controls which load. Similar dimmers are up to 50 percent deeper than the SwitchLinc Dimmer. Thanks to its slim design, it makes installation easy even in small junction boxes.
