Staircase Switch GRT8-LS
It is used for delayed switching off lights in the corridors, entrances, stairways, halls or for the delayed finish of fans (WC, bathroom, etc.).
Geya Staircase Switch is a kind of delay off time relay. Geya Staircase Switch can be used for delayed switching off lights in the corridors, entrances, stairways, halls or for the delayed finish of fans (WC, bathroom, etc.).
Geya Staircase Switch is a smart switch to control your lamps, and don’t need using two 2-way switches anymore.
Using Geya Staircase Switch can easily make Controlling a Lamp from 2 Places by 2-Way Switches come true. Geya Staircase Switch will close the lamps automatically.
Applications
It is used for delayed switching off lights in the corridors, entrances, stairways,
halls or for delayed finish of fans (WC, bathroom, etc.).
