## Summary description

Steinel PC4 Bluetooth switch coupler is a Steinel interface device designed to connect push buttons to compatible control systems via Bluetooth. It enables wireless integration of manual switches for remote control, lighting or automation setups. Ideal for retrofitting existing installations where a Bluetooth bridge for button inputs is required.

## Long description

Steinel PC4 Bluetooth switch coupler is an interface device that connects mechanical push buttons to compatible control systems via Bluetooth. Designed for integration into lighting and automation installations, the Steinel PC4 provides a wireless bridge for existing manual switches so they can send control signals to receivers, controllers or gateways without rewiring. The compact module supports standard push-button inputs and is intended for retrofitting where a wireless connection is preferred or required.
Advantages
The Steinel PC4 Bluetooth switch interface eliminates the need to run new control cables by converting physical button presses into Bluetooth signals compatible with supported control equipment. Its compact format allows discreet installation near the switch location or inside distribution boxes. The device preserves the original tactile operation of push buttons while enabling remote control and integration with automation systems.
Suitable for
Retrofitting existing light switches to add wireless control
Connecting push buttons to building automation controllers or gateways
Applications where running new wiring is impractical or costly
Installations requiring preservation of original switch hardware
When it may not be suitable
The Steinel PC4 is intended specifically for converting push-button inputs to Bluetooth signals; it is not a universal I/O module for complex logic, analog sensors, or direct power switching of high loads. It requires a compatible Bluetooth receiver or control system on the network side to interpret its signals. Environments with heavy Bluetooth interference or strict wired-only control policies may limit its effectiveness.
Key specifications
Interface: Push-button inputs to Bluetooth wireless output
Wireless protocol: Bluetooth (compatible with supported control equipment)
Mounting: Compact module suitable for mounting near switches or inside enclosures
Power: Low-voltage supply as required by the device (refer to manufacturer documentation for exact values)
Intended use: Retrofit and integration of manual switch inputs into wireless automation systems
How to use
Install the Steinel PC4 module close to the mechanical push button or inside the local distribution box and connect the button contacts to the module’s input terminals following the manufacturer wiring diagram. Power the module with the appropriate low-voltage supply and pair it with a compatible Bluetooth-enabled controller or gateway according to the pairing instructions. Once paired, test each button to confirm signals are received and mapped correctly in the target control system.
What to consider before purchase
Ensure your control system or gateway supports Bluetooth inputs from the Steinel PC4 or can be configured to accept its signals
Verify available mounting space and the electrical supply requirements for the module
Assess Bluetooth coverage and potential interference in the installation area
Confirm compatibility with the type of push buttons you plan to connect (normally open/closed).
Usage recommendations
For reliable operation, place the module where Bluetooth signal strength to the receiver is strong, keep wiring short and secure, and follow Steinel’s installation and safety instructions. Verify mappings in the control system after pairing and perform a functional test of each connected button before finalizing the installation.
