S4 Series Smart Home Switch
Compact 4-Key Handheld Wireless Control, No Battery Required
Primezen's S4 Series is a compact, self-powered wireless remote switch that can be held in the hand or fixed to a wall-mounted base using magnetic suction. With 4 keys, RF 433 MHz connectivity and a long operating range, it's built for flexible, on-the-go control of lights and connected appliances.

4-Key Remote
A Smarter, More Portable Way to Control Your Space
The Primezen S4 Series Smart Home Switch is a compact, self-powered wireless remote built for flexible everyday control. Unlike a fixed wall panel, the S4 can be kept handheld or fixed to a wall-mounted base using magnetic suction — so it can move with you between rooms, sit on a nightstand, or stay mounted near a doorway. Because it communicates over RF 433 MHz with an extended range of up to 100 metres outdoors, it suits homes, offices and hospitality spaces where control needs to travel, not just stay fixed to a wall.
- No wall cutting for additional switch wiring
- Magnetic base allows both handheld and fixed use
- Compact footprint suited to bedside or portable use
- Extended range for larger homes and outdoor areas
- Compatible with supported Primezen wireless automation solutions
How the Wireless Smart Switch Works
Press a Key, Handheld or Base-Mounted
Each of the 4 keys activates its own switching command, generating the operating energy needed from the mechanical press itself — whether the unit is in your hand or fixed to its magnetic base.
Wireless Signal Is Transmitted
The switch sends the command through RF 433 MHz communication to the paired receiver or controller, with a range of up to 100 metres outdoors.
The Connected Device Responds
The compatible controller operates the connected light or appliance according to the command received.
Note: A compatible Primezen controller or automation setup may be required depending on the application.
