Interra Combo Switch Actuators are versatile control devices that allow a variety of configurations such as lighting control, AC & DC motor control, or fan coil controls. They are intended to cover each automation requirement in a smart building for safe and efficient operations to guarantee increased comfort and versatility in residential and commercial applications. 


KNX communication enables information exchanges with KNX sensors, KNX Switches, or input devices and the integration with a building management system. Combo actuators have been developed to provide full control in smart building projects. The usage of these devices guarantees the efficient management and provision of rooms. 


Also, the manual control of the outputs is possible through the push buttons on the device. It allows the control of the outputs when bus communication failures between devices. Combo actuators are fed with power from the KNX bus and the complete configuration of the device is performed via ETS.
