MATCH 55 KNX TP Push Button Insert 420 secure

The TP version of our Push Button Insert has an integrated bus coupler for the KNX bus. The flat design allows mounting even on wall boxes with reduced space. Furthermore, the device includes a timed telegram sequencer and supports ten independent logic or timer functions.

  Push button interface

The device is also available as push button interface only. This variant does not include rockers and mounting frames but interface wires to connect standard switches with dry contacts. So you can use the same powerful application also for other switches or contacts. The build-in switches allow a fast testing of the configuration.
