Product Overview: The MS-1283 Advantage
The MS-1283 is a Snap-Action Micro Switch characterized by its rapid transfer of contacts from one position to another, regardless of the speed of the actuator. This “over-center” mechanism ensures clean make-and-break connections, reducing arcing and extending the electrical life of the component.
- High Current Capacity: Rated for 3A, making it suitable for small motors, solenoids, and power-heavy logic circuits.
- Precision Actuation: Offers a short travel distance with a distinct tactile “click,” providing immediate mechanical and electrical feedback.
- Sub-Miniature Footprint: Engineered for modern PCBs and compact handheld devices where internal space is at a premium.

Key Features & Build Quality
1. Industrial Grade Materials
The MS-1283 is housed in a high-strength, flame-retardant thermoplastic casing. The internal contacts are crafted from high-grade silver alloy to ensure maximum conductivity and resistance to oxidation over thousands of cycles.
2. Versatile Terminal Options
Designed for ease of integration, the MS-1283 comes with terminal configurations suited for:
-
PCB Solder Mounting: For direct integration into electronic boards.
-
Wire Soldering: For chassis-mount applications using lead wires.
3. “Make in India” Excellence
Produced at our state-of-the-art facility in Vadodara, every MS-1283 micro switch undergoes 100% functional testing. Our commitment to quality ensures that the operating point and release point remain consistent throughout the life of the switch.
Typical Applications
-
Consumer Appliances: Door interlocks for microwave ovens, vacuum cleaners, and coffee machines.
-
Industrial Automation: Limit switches for CNC machinery, 3D printers, and robotic arms.
-
Security Systems: Tamper-evident switches for alarm panels and smart locks.
-
Automotive: Glove box lighting, seatbelt sensors, and door latch mechanisms.
-
Office Equipment: Paper sensors in printers and photocopiers.
Why Source MS-1283 from Pran Electronics?
Pran Electronics Pvt. Ltd. combines over 50 years of group expertise in tool design with modern manufacturing agility. By choosing the MS-1283, you are selecting a RoHS-compliant, internationally-tested component that supports the “Make in India” initiative without compromising on global quality standards.
Engineering Tip: For high-vibration environments, ensure the MS-1283 is securely mounted using the integrated mounting holes to prevent “nuisance tripping” and ensure consistent actuation.
