Understanding the 19mm Push Button Switch Wiring Diagram is crucial for anyone embarking on electronic projects, whether it's a simple DIY gadget or a more complex control panel. This guide will demystify the process, ensuring you can confidently connect your 19mm push button switches.
What is a 19mm Push Button Switch Wiring Diagram and How Are They Used?
A 19mm push button switch wiring diagram is a visual representation that shows how to connect a 19mm diameter push button switch into an electrical circuit. These switches are incredibly common due to their robust construction and standard size, making them suitable for a wide array of applications. They act as momentary switches, meaning they complete a circuit only while being pressed and break the circuit as soon as the pressure is released. This makes them ideal for initiating actions, such as starting a motor, triggering a buzzer, or activating a light.
The utility of these diagrams lies in their ability to simplify complex electrical connections. For a standard 19mm push button switch, you'll typically encounter terminals that correspond to specific functions:
- Common (C): This is the main connection point for the circuit.
- Normally Open (NO): This terminal is disconnected from the common terminal when the button is not pressed. It connects to the common terminal when the button is pressed.
- Normally Closed (NC): This terminal is connected to the common terminal when the button is not pressed. It disconnects from the common terminal when the button is pressed.
The choice between using NO or NC terminals depends on the desired functionality. For instance, if you want a device to turn ON when the button is pressed, you'd wire it using the NO terminal. Conversely, if you want a device to turn OFF when the button is pressed, you'd use the NC terminal. Some advanced push buttons might have additional terminals for indicator LEDs, requiring a slightly more detailed diagram.
The applications for 19mm push button switches are vast and varied. Here are a few examples:
- Industrial Control Panels: Used for starting/stopping machinery, activating alarms, or resetting systems.
- Automotive Accessories: Powering auxiliary lights, controlling window lifts, or activating horn systems.
- Consumer Electronics: Integrated into arcade game controls, DIY electronics projects, and control interfaces for appliances.
- Security Systems: As panic buttons or activation switches for alarms.
The importance of following the correct wiring diagram cannot be overstated, as incorrect connections can lead to malfunctioning devices, electrical hazards, or even permanent damage to your components.
