Rayzeek Occupancy Motion Sensor Light Switch, 10A, US, No Neutral Required


The RZ021-10A-G motion sensor light switch uses an advanced passive infrared (PIR) motion sensor to detect people in the sensor zone and integrates a photocell for daylight sensing. Users can adjust the configuration by simply pressing the two push buttons on the panel without uncovering the wallplate. Besides occupancy and vacancy mode, the RZ021 series motion sensor switch introduces an innovative manual ON/OFF mode allowing the sensor switch to be used the same as a manual wall switch so that users can have manual override and keep the light always ON/OFF as long as needed. The RZ021 series is a direct replacement for the US standard 1-Gang wall switches. No neutral wire required(ground required) for RZ021-10A-G.

  • High Load Applications: 10A version capable for loading multiple lights, fans and air conditioners
  • Versatile Sensor Mode: Occupancy(Auto-ON, Auto-OFF), Vacancy(Manual-ON, Auto-OFF), Manual ON/OFF(Manual-ON, Manual-OFF)
  • Broad Voltage: Applicable for 110V residential and 277V commercial voltage in the US.
  • Flexible Wiring: Hot wire, Load wire, Ground wire. (Can be installed with a neutral wire with RZ021-10A-N)
  • Easy Installation: Fit in the US standard 1-Gang wall box

Customized Support

Incredibly versatile

The Versatile Rayzeek021-10A-G combines occupancy, vacancy and manual mode into one motion sensor wall switch for energy efficiency, convenience and compatibility.

With Rayzeek occupancy sensor light switches, you will never have to worry about looking for the light switch in the dark, forgetting to turn off the light wasting energy or having difficulties turning on the light with arms-full.

The all-round occupancy sensor switch is capable of nearly every residential and commercial application.

Unmatched sleek design

Regular 2-in-1 occupancy/vacancy sensor switches are thick and bloated. They contain mechanical dials and switches inside the panel cover for adjusting modes and settings.

Rayzeek occupancy sensors are smartly designed without any unnecessary dials or switches, all modes and settings can be adjusted by simply pressing the big and small buttons on the panel with light indicators.

The super-flat, low-profile and elegant design can fit any decor of residential and commercial applications.

Ever meet these problems?

manual mode solution for air conditioner

Lights constantly turning on and off near air-conditioner

Sudden heat change or a fixed heat source like HVAC can send distraction singles to PIR motion sensors.

In real-life cases, the air conditioner and motion sensor switches are already installed properly near each other and unable to change position, regular PIR motion sensors could be a problem by turning the light on and off randomly due to the detection of heat change.

Optimal motion sensors should always bring convenience to people, not trouble.

manual mode solution for mirror reflection

Lights keep on when room unoccupied

Similar to heat change, mirror reflection can also send false singles to PIR motion sensors to keep the light on even when the room is totally unoccupied.

Instead of finding the source and reducing the mirror reflections, which is usually relatively complicated, we need a smarter way to fix this problem.

The ultimate solution

Manual ON/OFF mode to bypass sensor mode

Rayzeek introduces a new feature to solve the problems in the above scenarios, the manual on/off mode, which can turn the occupancy sensor into a manually controlled sensor temporarily without changing the sensor’s setting and working mode.

To enter the manual on/off mode, short press the small button in the panel, the sensor will now work as a manual-controlled switch. In this mode, the sensor switch is similar to a mechanical switch, you can turn the light on/off by short pressing the small button. The sensor will still flash a red indicator light when motion detected but it will not control the lighting.

To switch back to the previous mode, short press the big button, it will work as a regular occupancy sensor again. All settings like working mode, light, and time-delay still remain the same.
