Radioswitch RSW

Airwave switch DW

Airwave switches are actuated by pressure waves created by any kind of pressure source. A rubber tube inside the weather seal of the door is used to create a pressure wave. When the pneumatic edge hits an obstacle, a pressure wave is created inside of the tube and this wave is recognized by the switch.

DW is a cost-efficient way to safeguard doors and gates against entrapment. These pneumatic switches can be installed without any special tools directly on site. Installation is as easy as measuring and cutting the weather seal extrusion and connecting the switch to a tube in the weather seal.
