When installing a magnetic contact on a movable window, what component must be placed on the movable portion of the window?

In the context of installing a magnetic contact on a movable window, the correct component to place on the movable portion of the window is the magnet. A magnetic contact system generally consists of two main components: a magnet and a switch or sensor.

For a movable window, the magnet is installed on the part of the window that opens and closes. When the window is closed, the magnet aligns closely with the switch or sensor mounted on the fixed frame of the window. This creates a closed circuit that signals to the security system that the window is secured. If the window is opened, the magnet moves away from the switch or sensor, breaking the circuit and indicating to the security system that there may be a breach.

The other components like the switch or sensor are typically installed on the fixed part of the window frame (the part that does not move) to detect the presence or absence of the magnet when the window is in either the open or closed position. The connector is not specifically involved in the detection process; rather, it helps to establish the electrical connection within the system. Thus, placing the magnet on the movable portion is essential for the effective operation of the magnetic contact installation.
