The spring-return rocker always returns to centre, giving occupants a clear indication of what they have pressed and preventing the confusion of a latching switch.
Gives building occupants simple, intuitive control over window opening and closing without requiring access to the main ventilation controller.
Compatible with 24V DC and 230V AC systems across the Topp and Ventec range, reducing the number of switch types needed on a project.
The rocker returns to centre automatically after each press, providing clear tactile feedback and avoiding the ambiguity of a latching switch that may be left in the wrong position.
A single switch provides both open and close commands (press up to open, press down to close), keeping the wall plate clean and uncluttered.
Compatible with 24V DC and 230V AC actuator systems, suitable across the full range of Topp and Ventec chain, linear and rack actuators.
Fits a standard surface-mount back box for neat installation alongside other switches and outlets at any wall position in the building.
Provides building occupants with intuitive push-button control of windows in offices, classrooms, and common areas where occupant override is required.
Used at desk or reception positions to give facilities managers direct manual override of specific ventilation zones without accessing the main controller.
Standard manual switch for 24V and 230V natural ventilation systems controlled by Topp TF24 or TF44 controllers.
Spring-return rocker returns to centre position after each press, making it clear when the switch is in open or close mode and preventing accidental continuous commands.
Two-position rocker gives direct open and close control of connected actuators at the press of a button: no key required.
Standard surface-mount wall box fits neatly alongside other wall switches and controls at any convenient position.
Works with both 24V DC and 230V AC actuator systems, suitable for use with the full range of Topp and Ventec actuators.
