What's the Difference Between NO Contacts and NC Contacts?

NO contact
NC Contact

NO Contacts:
usually, the initial state is not energized, the device is off, and only when you press the button, the device can start.

NC Contacts:
usually, the initial state is energized, and only when you press the button, the device will be powered off to realize the function.

What's the Difference Between Momentary and Maintained Push Button Switches?

Momentary Push Button Switches

Momentary Push Button Switches start working when you press the button and return to the initial state when you release it. A typical example is the Doorbell Switch, where the doorbell rings when you press the button and turns off when you release it.

Non-momentary Push Button switches

Non-momentary Push Button switches, when you press the button to start working, when you release the button to maintain such a locked state, when you repeatedly press the button when it can return to the initial state.

Push Button Switch Types

2-Position Push Button Switches
2-Position Push Button Switches

2-position push button switch is a type of switch commonly used in electronic and electrical systems. Here are its key characteristics:

  1. Two Positions: It has two distinct positions, typically labeled “on” and “off.” The design allows the switch to either complete an electrical circuit (“on”) or break it (“off”).
  2. Push Button Mechanism: The switch operates on a simple push mechanism. This means that you can change its position by pushing a button. This action either engages or disengages the circuit.
  3. Simple Operation: These switches are designed for ease of use. The user can easily activate or deactivate the switch with a single push.
  4. Applications: 2-position push button switches are used in a wide range of applications. They are found in industrial machinery, consumer electronics, vehicles, and other systems where a simple on/off control is needed.
  5. Variants: While the basic function is the same, these switches can vary in terms of size, color, design, and electrical specifications to suit different ap
Dual Push Button Switches
Dual Push Button Switches

A dual push button switch is a type of switch that features two buttons in a single unit, each button controlling a separate circuit or function. Here are some key aspects of dual push button switches:

  1. Two Buttons: Unlike a standard single-button switch, a dual push button switch has two buttons. These buttons are often side-by-side or one above the other.
  2. Independent Operation: Each button operates independently and can control a different circuit or perform a different function. For example, one button might turn a machine on, while the other turns it off.
  3. Compact Design: By combining two buttons into one unit, dual push button switches save space and can be more convenient than having two separate switches.
  4. Applications: Dual push button switches are common in industrial control systems, electronic devices, and machinery where multiple functions need to be controlled from a single location. For example, they might be used in a control panel for starting and stopping a motor.
  5. Variations in Design: These switches can come in various designs, including different colors for each button to indicate their function clearly (like red for stop and green for start), different shapes, and sizes depending on the application.
  6. Electrical Specifications: Like other switches, dual push button switches are designed with specific electrical ratings (like voltage and current capacity) to suit different applications.

These switches are valued for their functionality and efficiency, allowing control of multiple circuits or operations from a single, compact unit.

Push to Break Switches
Push to Break Switches

A “Push to Break” switch, also known as a Normally Closed (NC) push button, operates on a principle opposite to that of a standard push button switch. Here’s an explanation of its features and functionality:

  1. Normally Closed (NC) Operation: In its default state, a Push to Break switch completes the circuit, allowing current to flow. This is why it’s called “normally closed” – the circuit is closed (complete) when the switch is not being pressed.
  2. Breaking the Circuit: When the button is pushed, the circuit is broken or opened, interrupting the flow of electricity. This is the unique characteristic of a Push to Break switch – it disconnects or ‘breaks’ the circuit when activated.
  3. Reset Mechanism: Upon releasing the button, the switch returns to its default state, closing the circuit once again. This is usually achieved through a spring mechanism that brings the button back to its original position.
  4. Applications: Push to Break switches are used in applications where it is important to ensure a continuous operation or connection until an intervention is needed. For example, they might be used in emergency stop controls, alarm systems, or as a safety feature in various types of machinery and equipment.
  5. Design Variants: Like other types of switches, Push to Break switches come in various shapes, sizes, and designs, with different electrical ratings to suit a range of applications.

This type of switch is particularly useful in situations where the default, safe, or desired state is for the circuit to be closed, and only in specific instances should the circuit be opened or interrupted.

Push to Make Switches
Push to Make Switches

A “Push to Make” switch, also known as a Normally Open (NO) push button, is a type of switch that operates in a way that’s generally opposite to a “Push to Break” switch. Here’s an overview of its characteristics and how it works:

  1. Normally Open (NO) Operation: In its default, unpressed state, a Push to Make switch does not complete the circuit; it’s “open,” meaning no current flows through it. This is why it’s termed “normally open.”
  2. Making the Circuit: When the button is pressed, it closes the circuit, allowing electricity to flow. This action “makes” the circuit, hence the name “Push to Make.”
  3. Reset Mechanism: After the pressure is removed from the button, it usually returns to its original position due to a spring mechanism or similar. This opens the circuit again, stopping the flow of electricity.
  4. Applications: Push to Make switches are widely used in various applications. They’re common in consumer electronics, doorbells, and as start buttons in many devices. Essentially, they are used in any situation where the circuit needs to be completed temporarily.
  5. Design Variations: These switches come in different shapes, sizes, and electrical specifications to accommodate different uses. Some might have LED indicators, different button colors, or varying resistances.

Push to Make switches are fundamental components in many electronic systems, where a temporary connection is required to complete a circuit and activate a device or process.
