What is and how a 2-way key selector works for rollable metal blinds

The 2-contact key selector is an essential component for the control of roller shutters, especially in commercial premises. This device offers a safe and comfortable mechanism to upload or lower the blind, ensuring controlled access to the facility.

What is a 2-way key selector?

This is an electrical device that allows the engine of a metal shutter to be operated by a physical key. This selector consists of a cylinder where the key is inserted and an internal mechanism that activates or deactivates the current step to the engine.

The term "2 contacts" refers to the two main operating positions of the selector:

Uplink: Send a signal to the engine for the blind to be lifted.

Contact of descent: Send a signal to the engine for the blind to descend.

How does a key selector work?

The operation of the 2-connected key selector is based on a simple yet effective electrical circuit system. These are the main steps of your operation:

Insertion and turning of the key: The user enters the key into the selector and turns to the desired position, either to upload or lower the blind.

Circuit connection: When you turn the key, you close the corresponding circuit (up or down), allowing the electric current to reach the engine.

Engine Activation: The engine receives the signal and executes the action to upload or lower the blind.

Return to neutral position: Once the movement is completed, the user can turn the key back to the neutral position to interrupt the current, stopping the engine.
