Precision Circuit Control: 12.90mm x 6.80mm 3-Pin Push Off Switch 🔘🔌

The 12.90mm x 6.80mm 3-Pin Push Off Button Switch is a specialized electronic component designed for applications requiring a "Normally Closed" (NC) configuration. Measuring a compact 12.90mm in length and 6.80mm in width, this switch is engineered to maintain circuit continuity in its resting state and break the connection immediately upon being pressed. Its ultra-slim profile and three-terminal design make it an essential choice for high-density PCB layouts and precision consumer electronics.

Key Performance Features:

• ✅ Ultra-Compact Footprint: The 12.90mm x 6.80mm dimensions are ideal for space-critical installations where standard switches cannot fit.

• ✅ Reliable 3-Pin Configuration: Features three high-conductivity terminals that allow for versatile wiring, often used to toggle between two separate circuit paths.

• ✅ "Push Off" Functionality: Operates as a normally closed switch, making it perfect for safety interrupts or limit-sensing applications.

• ✅ High-Contrast Actuator: Equipped with a distinct red plunger for easy identification against the sleek black housing.

• ✅ Durable Molded Housing: Constructed from heat-resistant synthetic materials to ensure long-term stability under repeated mechanical stress.

Typical Applications

This 3-Pin Push Button is widely utilized in:

• Safety Interlocks: Used in devices where opening a door or panel must immediately cut power to the system.

• Precision Limit Switches: Ideal for 3D printers and CNC machinery to detect the end of travel for moving components.

• Small Household Appliances: Power control for handheld devices where a momentary "cut-off" feature is required.

• Electronic Prototyping: A popular component for breadboard projects and custom PCB designs requiring SPDT (Single Pole Double Throw) switching.

• 🏗️ Materials: Plastic Body with Metal Solder Lugs.

Top 3 Customer Questions & Concerns 🙋‍♂️

1. ⚡ Why are there three pins on a "Push Off" switch?

   • The three pins typically represent a Common (C), Normally Open (NO), and Normally Closed (NC) terminal. This allows the user to decide whether the circuit should break or flip to a secondary path when the button is pressed.

2. 🔧 Can this switch be used for high-current loads?

   • These switches are generally rated for signal-level or low-current power (e.g., 0.5A at 250VAC). For heavy machinery, they should be used as a trigger for a higher-rated relay.

3. 💪 Is the red button a locking toggle?

   • No, this is a momentary switch. The circuit only remains "OFF" as long as the button is held down; it returns to its "ON" state automatically upon release.
