Switch actuator 2-gang with 2 binary inputs Jung BT P S2 B2 U (JUNG HOME Puck)

Jung BT P S2 B2 U (JUNG HOME Puck) is a compact 2-gang switch actuator with two independent switching channels and two binary inputs, intended for building automation and smart-home applications. The device provides control of electrical loads through its two outputs while accepting external binary signals for integration with sensors, push-buttons or other switching devices. Its compact form factor and straightforward functionality make it suitable for installation in distribution boards or close to load points in residential and commercial environments.

Advantages

The switch actuator offers two independent channels for switching loads, enabling separate control of lighting circuits or small appliances. Two binary inputs allow direct connection of external switches and sensors for local or centralized control. The module is designed for easy integration into automation systems and supports stable switching performance suitable for routine building control tasks.

Suitable for

• Switching lighting circuits in homes and apartments
• Controlling small motors or heaters within rated limits
• Integration with sensors, push-buttons or alarm systems via binary inputs
• Centralized room control in commercial or residential installations

When it may not be suitable

This actuator is intended for switching tasks within its electrical ratings and may not be appropriate for directly driving high-power industrial loads or large motors without additional contactors or protective equipment. It is not a standalone controller for complex logic or automation scenes; full system functionality depends on the surrounding automation platform and configuration.

Key specifications

• Channels: 2 independent switching outputs
• Inputs: 2 binary inputs for external switches or sensors
• Mounting: designed for distribution board or installation near loads (compact form factor)
• Application: building automation, smart-home and centralized control systems

How to use

Install the actuator according to local electrical regulations, mounting it in a suitable enclosure or distribution board. Connect the two load circuits to the switching outputs and wire external switches or sensors to the binary inputs. Configure the device within the building automation platform or the central controller so that the outputs respond to input signals and automation commands. Verify correct wiring and test switching operation before putting the system into regular use.

What to consider before purchase

• Confirm the actuator’s switching ratings match the intended loads
• Ensure compatibility with your automation platform or central controller
• Plan mounting location and enclosure space for safe installation
• Verify required wiring and protection devices (fuses, circuit breakers)

Recommendations

Use the actuator for distributed switching close to loads to reduce wiring complexity, and combine it with appropriate protective devices and contactors when controlling inductive or high inrush currents. Regularly inspect connections and integration settings within your automation system to maintain reliable operation.
