Hager Lumina monostable (momentary) roller shutter switch WL0323, normally open, black

Hager Lumina WL0323 is a monostable (momentary) roller shutter switch in a black finish. Designed for manual operation of shutter and blind motors, the switch provides a normally open contact that closes only while the button is pressed. Its form factor matches standard wall-mounting frames and is suitable for installation in residential and commercial control panels where temporary contact activation is required for motorized window coverings.

Advantages

The momentary (monostable) action ensures the contact closes only during user input, reducing the risk of unintended continuous motor drive. The normally open configuration provides a clear fail-safe state when not engaged. A neutral black finish allows discreet integration with interior fittings, while compatibility with common wall-mount frames simplifies retrofit and new-install applications. The tactile button gives reliable manual control for short-duration commands.

Suitable for

• Manual control of roller shutters and blinds with motorized drives
• Integration into wall-mount frames for homes and offices
• Use in control panels requiring momentary contact inputs
• Temporary switching to trigger motorized awnings or screens

Key specifications

• Operation type: monostable (momentary) push-button
• Contact behavior: normally open (closes when pressed)
• Finish: black
• Mounting: standard wall-mount frame compatible
• Intended use: manual control for shutter/blind motors and momentary control inputs

How to use

Mount the switch into a compatible standard frame and connect wiring according to the motor control circuit or control panel diagram, ensuring power is isolated during installation. Press and hold the button to close the contact and activate the shutter or blind motor; releasing the button returns the switch to its normally open state and stops the signal. Use the switch together with the motor’s control relays or drive electronics as specified by the motor manufacturer.

Usage recommendations

Confirm the motor control voltage and wiring scheme before installation, and ensure protective devices such as circuit breakers and motor overload protection are installed according to local regulations. For long-term reliability avoid using the switch as a permanent power disconnect; it is designed for short, momentary actuation only. If integration with automated control systems is planned, check compatibility with relay modules or automation inputs.
