This model is with spring return From both sides

Electromechanical stairwell with maximum accuracy due to the small synchronous motor that controls the time measurement. Electromechanical stairwells generally have lower energy consumption than the electronic ones. Elpa 8 consumes only 1 VA during normal operation.The stairwell machine can be used in both 3 and 4-conductor systems. The maximum glow lamp load for the unit is 50mA.The stairwell has 2 different positions, one for constant light and one for automatic switching off after set time.Precise time interval with synchronous motor operation.Switch-on time 1 to 7min.Maximum glow lamp load 50 mA.Can be used in both 3 and 4-conductor systems.

This model is with spring return

In this model, an adapter can be fitted, which means that the key can only be removed when the switch is disconnected
