Rotary Knob vs Push Button Specs
Switch Style
The ANABIUP Rotary Dimmer Knob offers a traditional rotary interface. It is a replacement component designed for existing dimmer shafts. You must align it with a crescent-shaped axis for installation. This style provides tactile feedback and smooth operation through its corrugated edges. In contrast, the GE Cync Button Smart Switch uses a push button interface. It functions as a standard on/off switch. This style is familiar for basic lighting control. The GE unit is a complete smart switch, whereas the ANABIUP item is a knob replacement. You choose the style that matches your current hardware or desired control method.
Wiring Requirement
Wiring needs differ significantly between these two products. The GE Cync Button Smart Switch explicitly requires no neutral wire. This makes it suitable for older homes built before 1980 where neutral wires are often absent. It does require a ground wire and 2.4 GHz WiFi for operation. The ANABIUP Rotary Dimmer Knob is a physical replacement part. Its data does not specify wiring requirements because it replaces an existing knob on a pre-wired dimmer. You must ensure your existing dimmer shaft matches the internal ridge of the knob. If you need a new switch for a circuit without a neutral, the GE unit is the clear choice.
Smart Home Compatibility
Smart capabilities are a key differentiator. The GE Cync Button Smart Switch connects to Amazon Alexa and Google Home. It allows for voice control and remote management via the Cync App. You can set schedules and control lights from anywhere using your smartphone. No standalone bridge or hub is required. The ANABIUP Rotary Dimmer Knob has no listed smart home compatibility. It is a mechanical component that relies on the underlying dimmer switch for any electronic functions. If you want voice control or app-based scheduling, the GE switch provides these features directly. The ANABIUP knob offers no such connectivity.
Connectivity
Connectivity options vary by product function. The GE Cync Button Smart Switch uses 2.4 GHz Wi-Fi to connect to your network. This enables remote access and smart features without additional hardware. The ANABIUP Rotary Dimmer Knob has no listed connectivity specs. It is a passive mechanical part that attaches to a dimmer shaft. It does not communicate with your home network or other devices. If you need your lighting to respond to voice commands or app triggers, you must use a smart switch like the GE unit. The ANABIUP knob is purely for manual operation.
Dimensions
Physical size and form factor are important for installation space. The GE Cync Button Smart Switch measures 3.78 inches in width, 5.55 inches in height, and 3.37 inches in length. It weighs 9.6 ounces. The ANABIUP Rotary Dimmer Knob is much smaller, measuring 1.45 inches in width, 1.6 inches in height, and 1.45 inches in length. Its compact design saves space and fits into shallower wall boxes. It is described as having an ultra-thin shape with half the depth of traditional rotary dimmers. If you have limited space in your electrical box, the ANABIUP knob is a better fit.

Homes without neutral wires
Older homes often lack neutral wires in switch boxes. This GE Cync switch is designed for no-neutral installations. It requires only a ground wire and 2.4 GHz WiFi. This makes it easier to install in pre-1980s homes. You avoid complex rewiring while still gaining smart home features and remote scheduling capabilities.

Frequently asked questions
Can I use a rotary dimmer knob for simple on/off control?
No, the ANABIUP Rotary Dimmer Knob is designed to replace worn dimmer controls, not to provide basic on/off switching. It attaches to existing crescent shafts to refresh the look and feel of your lighting. If you need simple toggling without dimming capabilities, a push button style is more appropriate for your setup.
Do I need a neutral wire for the GE Cync switch?
Yes, the GE Cync Button Smart Switch requires a neutral wire for installation.

You must verify your wall box contains a neutral conductor before purchasing this specific model to ensure proper connectivity.
Which smart switch works with Alexa and Google Home?
The GE Cync Button Smart Switch is compatible with both Alexa and Google Home. This push button model allows you to control your lights using voice commands through these major platforms.
