The 1L-MSR-105T magnetic micro switch from 1 LEAP Technologies is a compact and robust magnetic reed switch specifically designed for applications where a clean, concealed, and mechanically secure installation is required. This model is engineered with a 3/8″ diameter body and an integrated terminal connector, allowing direct electrical connection without external cable joints. Its recessed mounting design ensures that the switch remains protected inside the mounting surface, making it suitable for demanding industrial and architectural environments where durability and reliability are critical.
Unlike general-purpose electrical switches, the 1L-MSR-105T is developed for fixed installations where stable alignment, controlled operating gaps, and long-term performance are required. This makes it an ideal solution for professional installations handled by system integrators, panel builders, and sensor-based automation designers.
Key Features

- Easy & Quick installation
- No Cable Joints, Better Reliability
- Can use solid or stranded 22 AWG Wire
- Short Length
- Operate Gap 5/8″ (16mm) min.
Compact 3/8″ Diameter with Terminal Connector
One of the defining features of the 1L-MSR-105T is its 3/8″ diameter cylindrical body, which allows it to be easily recessed into pre-drilled mounting holes. The built-in terminal connector eliminates the need for soldered or crimped cable joints, reducing installation time and minimizing the chances of connection failure. This design directly improves system reliability, especially in environments where vibration, moisture, or maintenance access is limited.
Compatible with Solid or Stranded 22 AWG Wire
The 1L-MSR-105T supports both solid and stranded 22 AWG wire, providing flexibility during wiring and system integration. This compatibility allows the switch to be easily integrated into control panels, junction boxes, and automation circuits without requiring special adapters or customized wiring solutions. For sensor manufacturers and automation engineers, this flexibility reduces design constraints while maintaining electrical stability.
Controlled Operating Gap for Accurate Switching
This magnetic reed switch operates with a minimum operating gap of 5/8″ (16 mm), ensuring reliable actuation only when the paired magnet is correctly positioned. This controlled operating distance is critical in applications where precise alignment is required to avoid false triggering or missed signals. The defined operating gap makes the 1L-MSR-105T magnetic micro switch suitable for fixed-position sensing applications rather than dynamic consumer electronics.
Easy and Quick Installation for Professional Applications
The recessed mount magnetic switch design of the 1L-MSR-105T allows installers to achieve a flush, professional finish. Once installed, the switch remains firmly seated within the mounting surface, protecting it from accidental impact or tampering. This ease of installation is particularly valuable in large-scale projects such as shipbuilding, architectural structures, and industrial enclosures, where installation efficiency and repeatability are essential.
Applications of 1L-MSR-105T
The 1L-MSR-105T is designed for specific industrial and structural applications where recessed mounting and high reliability are required. It is not intended for compact consumer electronics such as laptops, but excels in the following sectors:
Shipbuilding Industry
In shipbuilding environments, components must withstand vibration, humidity, and long service periods. The recessed mount design and terminal connector of the 1L-MSR-105T make it suitable for hatch position sensing, access panel monitoring, and internal door status detection in marine vessels.
Architectural Installations
In architectural projects, aesthetics and concealed installation are essential. The 1L-MSR-105T magnetic switch can be embedded into doors, frames, or structural elements for security sensing, access control, and position detection, without compromising visual design.
Industrial Automation and Control Panels
As a precision magnetic micro switch, this model is ideal for industrial automation systems, enclosure monitoring, and machine safety sensing where reliable switching and clean wiring are required.
Automotive and Heavy Equipment Structures
While not used in consumer automotive electronics, the magnetic reed switch for automotive–related structural sensing can be applied in specialized vehicle bodies, service compartments, and industrial vehicle panels, where rugged mounting and defined operating gaps are needed.
