Linptech E5 ultra-thin smart display switch with Bluetooth Mesh 2.0. It features a borderless large display and long-distance sensing; automation can change the displayed information. A Bluetooth Mesh gateway is required and sold separately. Supports the Mi Home app, Xiaomi HyperConnect, and Super Xiao Ai control.

6.9 mm flush panel with a minimalist design; a large, bezel-free screen displays multiple kinds of information in real time.

Smart display of button information makes names and status easy to see. Customizable on-screen text can display family messages and reminders.

View the time, date, and weather. Stepless distance sensing; display content supports three-stage switching.

Newly upgraded for an attractive design, display interaction, and safety. The new generation features an ultra-thin, flat, bezel-less design that looks good with the screen on or off. It supports large-screen interaction and can display a variety of information.

Automation can change the information shown on the display. It supports stepless distance sensing for finer distance-sensing adjustment. It has overcurrent and overtemperature protection.

Ultra-thin, flat design with a 6.9 mm projection from the wall.

Frameless OLED large display. The single screen is 0.96 inches with a resolution of 128 × 64; the screen width corresponds to the width of a triple-key button. When displaying “Homecoming mode,” the single screen consumes only 0.03 W.

Can be installed in a row with Linptech E3S series switches and sockets.

Display scenes include spotlight, homecoming mode, and pendant light. A single-key switch has one screen; a double-key switch has two screens; a triple-key switch has three screens; and a four-key switch has two screens.

Supports custom display text and real-time display of important information. It can serve as a smart message board at home for family reminders, notes, and short mood messages.

The switch display can show custom text, such as “Gazing at the moon at the horizon together, drinking the Yangtze water together,” “Longing flows with the waves; hearts remain close across a thousand miles,” “Study champion’s rest room,” and “Sleep well.”

Automation can change the information displayed on the screen. For example, when someone is in a designated area, the screen can change from displaying the time to displaying the text “Occupied”; when no one is there, it can display the time again. Each screen supports 3 custom text entries, with up to 10 Chinese characters per entry. Automation can select one of these entries or display the time, date, or weather.

The screen can display the time, date, and weather in real time, as well as reminders.

The self-developed infrared transmit-and-receive sensing system provides stepless distance measurement, and the sensing distance can be adjusted steplessly. When “Sensing-triggered screen saver” is enabled, waking the screen from farther away opens the screen saver. The illustrated screen-saver sensing distance is 80 cm, with an adjustment range of 20–110 cm.

When “Display button names by proximity” is enabled, button names are displayed when triggered at a closer distance. The sensing distance is adjustable; the example shown is 20 cm, with an adjustment range of 10–100 cm. Sensing distance depends on the reflectivity of clothing and the background; the values shown are for reference, and actual use may vary.

Three-stage proximity sensing: the screen turns off when a person is farther away; as they approach, it displays information such as the time, weather, and date; when they move closer to the switch, it displays the key names. Within 0.3 m of the switch, the screen displays key names. At 0.3–1 m, it displays the screensaver, clock, calendar, and weather. Beyond 1 m, when no one is detected, the screen turns off. Distances are examples; the specific distance can be set in the app.

Dual use: four physical keys can provide eight controls. Lightly touch the center of the screen to switch among four wireless switches and control other devices and scenes through automation.

Supports Bluetooth Mesh 2.0, with faster response, more consistent scenes, and automatic remote OTA upgrades. Supports up to 32 physical groups and faster network setup. Bluetooth module SDK firmware version: 3.0.4.

With a neutral wire and live wire reserved in the switch box, no complex wiring or replacement of lighting equipment is required. Set scenes such as remotely turning off lights when leaving, automatically turning them on when returning home, or turning them off by voice before bed.

Lights can turn on automatically when you arrive home, adding a sense of occasion to everyday life.

Control lights by voice: turn them on or off with a spoken command.

Requires a Bluetooth gateway and the necessary sensors or a voice assistant speaker.

Supports increasing or decreasing brightness and warming or cooling the color temperature.

After switching to wireless-switch mode, always-on power mode can be set to keep smart lights connected; buttons can be configured to control lighting automations.

Fast and Standard modes are available. Fast mode responds more quickly to button presses but does not support double-click or long-press.

The relationship between relays and buttons can be configured.

The device state after power is restored can be set to Off, Memory, or On. With Off selected, the device is off whenever power returns; with Memory selected, it resumes its state from before the power outage; with On selected, it turns on whenever power returns.

Presence or absence can be used as a scene trigger condition. Enable the “Proximity/Distance Reporting” option in the app’s “Screen Display Settings.”

Switch interlock mode can control special equipment: turning on one switch forces the other switches off. This mode can be used with some projection screens, fans, and other equipment.

Switches can control one another locally for two-way control. They can also be paired with a Linptech Bluetooth wireless switch.

Three-part design: the switch is divided into three sections. The screens for the one-key and two-key versions are at the top, while the four-key screen is in the middle. Linked switches can create a staggered screen layout. The one-, two-, and three-key screens have physical buttons below them; the four-key screen has physical buttons above and below. The buttons are next to the screen, making their functions more intuitive to view.

The diagram shows the physical-button and screen layout of the switch.

Looks good with the screen off or on. When the screen is off, the panel and display area form a seamless whole.

Linptech E5 slim smart display switch. When the screen is on, the background appears pure black without light leakage.

The switch bottom shell is formed as one piece for a sturdy, neat construction.

Floating circuit board: The buttons and circuit board are suspended above the bottom shell. Slight deformation of the shell does not affect button actuation.

The elastic arm and electronic touch buttons use a stacked design. With the button cover removed, the interior is neatly arranged, with no obvious exposed circuit board.

The button gap is approximately 0.3 mm. The integrated-button design has a clean appearance, and precision tooling helps ensure an even gap.

The rotary snap-fit design helps prevent damage to the clips when removing the buttons.

The U-shaped wiring terminal is designed for switches, with a large conductor contact area for reliable connection. It accommodates up to six 1.5 mm² solid wires at the same time, making parallel wiring easier.

Enhanced safety

Zero-crossing arc suppression technology: Monitors the zero-crossing point of AC in real time and opens the relay at that point to help prevent high-voltage arcing and extend product life.

Tested with 100,000 loaded on/off presses for durability.

High-specification fire-resistant base housing: flame-retardant at 850°C.

Overcurrent protection: the fuse melts when current is excessive to help ensure electrical safety.

Overtemperature protection: a temperature sensor disconnects the load if the circuit board overheats. When the temperature returns to normal, controllable operation is restored automatically.

E5 switch dimensions: The panel is 86 mm wide and 86 mm high. The diagram labels the panel thickness as 6.9 mm; the total side depth is labeled 21 mm for the one-, two- and three-button versions, and 28.7 mm for the four-button version.
