50-Pack Micro Limit Switches — Reliable SPDT Action for Arduino, DIY Electronics & More

Get precision control in your electronics projects with this pack of 50 CYT1073 Micro Limit Switches. Each switch features a 3-pin SPDT (Single Pole Double Throw) configuration with both Normally Closed (NC) and Normally Open (NO) contacts, delivering fast, snap-action switching in a compact black-and-white plastic housing. Perfect for makers, hobbyists, and engineers alike.

Key Specifications

  • Model: CYT1073
  • Configuration: SPDT — 1NC + 1NO (3-Pin)
  • Rated Voltage: 125V AC
  • Current Rating: 1A – 3A
  • Material: Durable Plastic Housing
  • Color: Black & White
  • Terminal Type: PCB Terminals (Circuit Board Mount)
  • Quantity: 50 Pieces per Pack
  • Made in: Mainland China

How It Works

These micro limit switches operate via an external mechanical force — applied through pins, buttons, levers, or rollers — which acts on an internal reed. When the force reaches a critical threshold, the reed snaps instantaneously, causing the moving contact to make or break with the fixed contact at high speed. When the force is removed, the reed reverses instantly, resetting the switch. This snap-action mechanism ensures consistent, repeatable performance with minimal contact bounce.

Features & Benefits

  • ✅ Snap-Action Design: Small contact spacing, short stroke, and fast break/make action for responsive switching
  • ✅ Versatile SPDT Output: Both NC and NO outputs available — use the circuit state that best suits your design
  • ✅ PCB-Ready Terminals: Easy to solder directly onto circuit boards for a clean, secure connection
  • ✅ Compact Form Factor: Tiny size makes these ideal for space-constrained builds
  • ✅ Great Value: 50-piece pack ensures you always have spares on hand for prototyping and production

Wide Range of Applications

These micro limit switches are trusted across a broad spectrum of uses:

  • 🖱️ Computer mice & car mice
  • 🤖 Arduino projects & DIY robotics
  • 🏠 Small home appliances (microwave ovens, rice cookers)
  • ⚡ Electric tools & building automation
  • 🔥 Gas water heaters & gas burners
  • 📡 Communications equipment

Frequently Asked Questions

Q: Are these micro limit switches compatible with Arduino projects?

A: Yes! These CYT1073 SPDT micro limit switches are widely used in Arduino builds. Their 3-pin PCB terminal design makes them easy to wire into breadboards or solder onto circuit boards. They work great as end-stop sensors in 3D printers, CNC machines, and other Arduino-driven motion control projects.

Q: What is the difference between the NC and NO terminals on these SPDT switches?

A: SPDT stands for Single Pole Double Throw. The NC (Normally Closed) terminal maintains a closed circuit when the switch is at rest and opens when the actuator is pressed. The NO (Normally Open) terminal is open at rest and closes when the actuator is engaged. You choose which terminal to use based on whether your circuit needs to activate or deactivate on trigger.

Q: What voltage and current can these switches handle?

A: Each switch is rated for up to 125V AC and handles a current range of 1A to 3A, making them suitable for low-voltage control applications in electronics, appliances, and automation systems.

Q: How many switches come in this pack?

A: This listing includes a pack of 50 CYT1073 micro limit switches, giving you plenty of units for prototyping, repairs, and production builds.
