Wall Power Switch Grandview WS-MI Up/Down Control for Motorized Projection Screens

The Grandview WS-MI wall power switch provides tactile up/down control for motorized projection screens and similar electric roller devices. Designed for wall-mount installation, the switch offers direct local control of screen movement and power, compatible with Grandview motors and systems that accept a two-button up/down input. Its compact design and clear operation make it suitable for meeting rooms, classrooms and home theater installations where a simple, reliable control point is required.

Advantages

The WS-MI switch delivers straightforward directional control with a minimal footprint, enabling precise up and down movement of motorized screens without navigating remote controls or control systems. Its mechanical interface is easy to operate and install in standard wall boxes. The switch supports integration with existing wiring and provides immediate tactile feedback for users, reducing setup complexity and minimizing points of failure compared with more complex control panels.

Suitable for

• Motorized projection screens in conference rooms and boardrooms
• Classroom and lecture-hall projection systems
• Home theater and media room retractable screens
• Roller blinds or projection surfaces with compatible two-button motor inputs
• Local manual control alongside automated control systems

Key specifications

• Wall-mount switch with two-button up/down control
• Designed for use with compatible motorized screens and electric roller devices
• Standard single-gang installation form factor for flush mounting

How to use

Install the WS-MI in a standard wall box and connect the switch wiring to the motor control terminals according to the motor manufacturer’s wiring diagram and local electrical regulations. Press the up button to raise the screen and press the down button to lower it; release the button to stop movement when the desired position is reached. If integrating with additional control systems, ensure the switch wiring and control logic are compatible and that motor limits and safety features are configured before regular operation.

Usage recommendations

For reliable operation, have a qualified technician perform the electrical installation and confirm compatibility with your motorized screen. Test travel limits and any safety sensors after installation and periodically inspect the switch and connections for wear or loosened terminals. Avoid exposing the switch to moisture or heavy impact; use the switch as a local control complement to centralized automation when needed.
