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

10 Minute Quick Installation

The RZ021-10A-G series is designed for the US markets for single-pole applications. The 110V-277V voltage range works well in homes and offices and the 5A current rating is competent for daily uses. RZ021-10A-G is a 3-wire switch and does not require a neutral wire to work.

Exclusive ON/OFF Mode

One significant drawback after upgrading to motion-activated light switches is that you partially lose the ability to manually control your lights. It’s not possible to keep the lights ON like you’re used to with the good old wall switch.

The Best Of Both Worlds?

Rayzeek introduces the exclusive ON/OFF mode, allowing users to permanently keep the load ON or OFF the same as a standard light switch. It’s so convenient that users can seamlessly switch between detection mode and manual mode with only one tap.

Say goodbye to all these real-life headaches.

Pets Activate the Light at Night

Dogs and cats are active at night and might frequently trigger your motion light to turn on. That’s their nature. While most motion sensor switches do not have pet-immune features, false positives at night can be a real headache.

Select vacancy or OFF mode, especially in laundry rooms or the kitchen where your pets usually play around.

Take a Relaxing Long Bath

On average, people spend at least 8 minutes in the shower. When taking a relaxing bath at night, the light might unexpectedly turn off if the sensor can’t detect your presence in the bathing area. It can be an unpleasant experience that spoils the mood

Enter ON mode to keep the light always ON during the shower. Enjoy your hot and relaxing bath for as long as your like.

Lighting in Your Kids’ Bedroom

A vacancy sensor switch is used in bedrooms to reduce the electricity waste from the lighting left on by forgetful kids. Occupancy sensors aren’t suitable because they might activate the light at night, waking up kids, but it’s still handier in the daytime.

Now you can use occupancy sensor mode in your kid’s bedroom for the whole day. When it’s bedtime, touch the OFF button to keep the light off for the whole night.

Light False on in Empty Spaces

A fixed heat source(HVAC or hot wind) or even mirror reflection may send false positive IR signals that keep the light on when the space is unoccupied. Most of the time, it’s impossible to relocate the sensor’s position or the heat source as they’re fixed.

When the PIR sensor constantly detects signals and is falsely triggered, select OFF Mode to bypass motion detection

False off With People in the Room

Lights might falsely turn off if the sensor fails to detect the presence of people, e.g., the room is large, has obstacles blocking the IR signal, or fine motion activities such as reading or typing. It’s frustrating to repeatedly re-activate lights by moving your body.

When we need to permanently keep the light ON, enter ON mode by tapping the small button and exit without losing previous settings.
