Button switches, commonly referred to as push-button switches, are essential components in various electronic devices and systems. They control the flow of current within circuits through their unique operation and contact types, allowing users to activate or deactivate functions with simple presses or releases.

Operation Principles of Button Switches

Button switches typically function by completing or interrupting circuits upon pressing or releasing. When the button is pressed, it comes into contact with conductive material inside the switch, allowing current to flow through the circuit. Conversely, when the button is released, the contact is broken, interrupting the circuit and stopping the flow of current. This mechanism enables the switch to control the activation or deactivation of connected components.

Composition of Button Switches

Button switches consist of a button or actuator, a housing or enclosure, and internal components such as contacts, springs, and terminals. The actuator is the part pressed by users to operate the switch, while the housing provides protection and support for the internal components.

Understanding Latching and Momentary Button Switches

Switch actions are classified into latching and momentary types, distinguished by their behavior after activation. Momentary switches, also known as non-lock switches, provide a momentary connection signal upon pressing, returning to their original position when released. On the other hand, latching switches, also referred to as lock switches, maintain their state (either on or off) until pressed again to change it. They are commonly used for power switches, requiring toggling between on and off states.

NO / NC / COM Contact Circuit of Button Switches

The NO (Normally Open), NC (Normally Closed), and COM (Common) terminals of button switches describe their common terminal terms, defining their basic circuit connection modes.

NO / NC / COM Contact Circuit of Button Switches

These terminals control the opening and closing of button switches, thereby controlling the circuit's on and off states. This combination provides the flexibility of button switches in various applications, such as using the NO terminal to trigger an action or the NC terminal to prevent one.

Button switches are versatile components, playing critical roles in electronic devices and systems, from simple switching functions to complex circuit controls.
