Interruptor com Sensor de Movimento para Iluminação
Motion sensor light switch, also known as light sensor switch, or occupancy sensor switch, is a motion-activated switch that controls the light automatically for you. The motion sensor switch turns on the light when the built-in motion sensor detects your presence in the room and turns the light off when the room is vacant.
It’s a convenient way to add lighting automation to your home with a hands-free, no-touch lighting experience. Moreover, motion sensor switches help homeowners save energy easily by preventing electricity waste from lights left on.

Versatile 3-In-1 Sensor Mode
RZ021 motion sensor light switch utilizes PIR(passive infrared) technology with advanced microcontrollers for superior motion detection sensitivity and performance.
RZ021 sensor switch includes three working modes:
- Occupancy Mode: The light automatically turns on and off by the motion sensor. (Auto-on/Auto-off Mode)
- Vacancy Mode: Press the button to manually turn on the light and the light automatically turns off. (Manual-on/Auto-off Mode)
- ON/OFF Mode: Perform exactly like a single pole light switch. You can manually keep the light on or off. (Manual Override Mode)

Low-Profile & Sleek Design
The low-profile, sleek, minimalist design allows the RZ021 motion sensor switch to fit in every style of decor and blend in your home seamlessly. Besides the aesthetics part, our switch design is extremely practical as well. All adjustment and operation process is achieved by pressing the two buttons on the panel. The switch does not contain any toggles or dials for adjusting settings or switching modes. This makes the RZ021 motion sensor switch look modern, neat, and slim on your wall.

Made for Every Home
The RZ021-5A-G is an upgrade and direct replacement for regular single-pole light switches in the US. The 120V voltage range works well in homes and offices and the 5A high current rating is competent for daily uses loading multiple fixtures.
The 3-wire, no-neutral required RZ021-5A-G is perfect for retrofit projects for old houses that do not have a neutral wire available in their wall boxes. Instead, it only requires a ground wire to work. No extra re-wiring cost.

Wiring Diagram
The RZ021 motion sensor switch is hardwired and line-voltage powered. It requires a hot wire, load wire, and ground wire to function. The wiring is standard and the same as other switches.
- Connect black L wire with the live wire from the source
- Connect red L1 wire with the load wire to your light
- Connect green G wire with the ground wire
*The hotwire and load wire are not interchangeable.
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.

Hazel M –
I recently purchased 10 pcs of the 021-5a-g sensor switches and I am extremely satisfied with my purchase. The installation process was simple and straightforward, and the motion sensor switch has been working flawlessly.
One of the best features is the manual mode, as I no longer need to re-activate the sensor constantly to keep the light on. Overall, I would highly recommend it to others. This little unit is one of a kind and a real game-changer.
