George Risk Industries M-19 Magnet 3/16 X 1 Inch Contact

Product Description

The George Risk Industries M-19 is a small-format replacement magnet designed for use with surface-mount and recessed security contact switches. Measuring 3/16 inch in diameter and 1 inch in length, this cylindrical magnet provides the magnetic field necessary to actuate reed-switch-based door and window contacts. It is a direct-replacement component for installers who need to swap out a failed or missing magnet without replacing the entire contact assembly. Security and low-voltage alarm technicians are the primary trade installing this component in residential and light commercial intrusion detection systems.

This magnet is used in door, window, and gate contact applications where a separate magnet and switch body are mounted opposite each other on a frame and moving surface. When the door or window closes, the magnet brings the reed switch into its normal state. The M-19 is sold as a single unit and fits into standard contact housings that accept a 3/16-inch diameter magnet body.

Key Features

• Compact cylindrical form factor: 3/16 inch diameter by 1 inch length
• Designed to actuate reed-switch security contacts at correct gap distances
• Sold individually for single-point replacement without full assembly swap
• Fits standard miscellaneous contact housings accepting 3/16-inch magnet inserts

Compatibility

Designed as a replacement magnet for reed-switch-based door and window security contacts that accept a 3/16-inch diameter by 1-inch magnet component.

Installation Notes

Low-voltage alarm and security technicians typically install this component as part of a door or window contact system. Verify the existing contact housing accepts a 3/16-inch diameter magnet before ordering. Ensure the alarm panel zone is bypassed or the system is placed in test mode before removing or replacing contact hardware. Align the magnet body parallel to the reed switch during installation to maintain proper actuation gap.
