What are Push Button Switches?

Push button switches are the unsung heroes of modern technology, providing a simple yet essential function in controlling electrical circuits. These mechanical devices are designed to be manually pressed, activating an internal switching mechanism that either breaks or initiates a circuit. They come in various shapes, sizes, and configurations to suit different design requirements.

The operation of push button switches is straightforward. When the button is pressed, it either completes the circuit (in the case of a normally open switch) or breaks the circuit (in the case of a normally closed switch). This actuation mechanism can be momentary, where the switch function only continues as long as the button is pressed, or maintained, where the switch function stays latched in that status after actuation.

Push button switches can be classified based on their switching circuit, such as single pole, single throw (SPST), single pole, double throw (SPDT), double pole, single throw (DPST), or double pole, double throw (DPDT). These different configurations allow for the control of one or multiple circuits simultaneously, depending on the application requirements.

When considering push button switches for a specific design, it is important to take into account key specifications such as termination style, voltage rating, current rating, Push button switches head height, pitch, Push button switches head cap options, and IP rating. These specifications ensure compatibility with the design’s performance criteria and environmental conditions.

Push button switches find widespread use in various applications, ranging from household appliances and power tools to industrial controls and consumer electronics. Their versatility and reliability make them indispensable in controlling electrical circuits and providing user interface inputs.

In conclusion, push button switches are essential components that enable manual control of electrical circuits. Their diverse range of types, specifications, and applications make them a vital part of modern technology. So, the next time you press a button to turn on a device or activate a function, remember the humble push button switch working behind the scenes to make it happen.

How do Push Button Switches Work?

Push button switches, also known as pushbutton switches or simply push buttons, are mechanical devices used to control electrical circuits. They operate through a simple in-out actuation mechanism. When the operator manually presses the button, it actuates an internal switching mechanism that either breaks (off) or initiates (on) a circuit.

Push button switches can be categorized as either momentary or maintained switches. Momentary switches only remain in the on position as long as the button is pressed, while maintained switches stay latched in the on or off position after being actuated.

These switches come in various types, such as normally open (NO) or normally closed (NC) switches. Normally open switches complete the circuit when actuated, while normally closed switches break the circuit when actuated. The functionality of push button switches can be further defined by the switching circuit they utilize, such as single pole, single throw (SPST), single pole, double throw (SPDT), double pole, single throw (DPST), or double pole, double throw (DPDT).

When it comes to specifications, push button switches have different termination styles for mounting options, voltage ratings, current ratings, Push button switches head heights, pitch, and Push button switches head cap options. They can also have an IP rating to resist moisture and dust ingress.

Push button switches are widely used in various applications, including vending machines, household appliances, power tools, and industrial controls. They provide a convenient and reliable way to control electrical circuits and perform specific functions.

In conclusion, push button switches are essential components in modern applications, offering versatility and ease of use. Their basic operation, different types, and key specifications make them suitable for a wide range of electronic devices and equipment.

Types of Push Button Switches

When it comes to push button switches, there is a wide range of types available to suit various applications and design requirements. Let’s explore some of the most common types:

  1. Momentary Switches: These switches are designed to return to their original position once the actuation force is removed. They are commonly used for applications where a temporary action is required, such as turning on a light or activating a doorbell.

  2. Latching Switches: Unlike momentary switches, latching switches stay in their actuated position even after the actuation force is removed. They are ideal for applications that require a maintained state, such as power on/off switches.

  3. Normally Open (NO) Switches: These switches have an open circuit when not actuated and close the circuit when pressed. They are commonly used for applications where the circuit needs to be closed to initiate a specific function.

  4. Normally Closed (NC) Switches: In contrast to NO switches, NC switches have a closed circuit when not actuated and open the circuit when pressed. They are often used in safety-critical applications where the circuit needs to be interrupted to prevent a specific function.

  5. SPST Switches (Single Pole, Single Throw) : SPST switches have two terminals and can either open or close a single circuit. They are commonly used for simple on/off functions, such as controlling a motor or a light.

  6. SPDT Switches (Single Pole, Double Throw ): SPDT switches have three terminals and can control two separate circuits. They are often used for applications that require switching between two different functions or states.

  7. Double Pole, Single Throw (DPST) Switches: DPST switches have four terminals and allow for the simultaneous control of two isolated circuits. They are commonly used in applications where one circuit needs to be controlled independently from another.

  8. DPDT Switches (Double Pole, Double Throw ): DPDT switches have six terminals and can control two separate circuits simultaneously. They are often used in more complex applications that require multiple functions or states.

These are just a few examples of the types of push button switches available. Each type offers unique functionality and can be selected based on the specific requirements of your application. Remember to consult datasheets and consider factors such as voltage rating, current rating, and Push button switches head height to ensure compatibility with your design.

Key Specifications for Push Button Switches

When it comes to selecting the right push button switch for your application, there are several key specifications to consider. These specifications will ensure that the switch is compatible with your design’s performance criteria and meets your specific needs.

Termination Style: Push button switches come in various mounting options, including gull wing, pin terminal, wire lead, and screw terminal. Choosing the right termination style is crucial for proper installation.

Voltage Rating: Push button switches have a maximum voltage rating, typically up to 660 V. It is important to select a switch that can handle the voltage requirements of your circuit.

Current Rating: The maximum current that can flow through the switch is another important specification to consider. Push button switches can handle currents up to 20Amp.

Push button switches head Height: Push button switches come in different Push button switches head heights, such as flush, 3.3 mm, and 5.4 mm. The Push button switches head height should be chosen based on the available vertical space and the need to avoid accidental actuation.

Pitch: The pitch refers to the center-to-center distance between the switch’s pins. Common pitch options are 2.54 mm or 5.08 mm.

Push button switches head Cap: Push button switches offer a variety of Push button switches head cap options, including different colors and finishes. The choice of Push button switches head cap depends on the application requirements or user preference.

IP Rating: Push button switches can be rated or non-rated for their resistance to moisture and dust ingress. Consider the IP rating based on the environmental conditions in which the switch will be used.

These specifications, along with others mentioned in the previous sections, will help you make an informed decision when selecting a push button switch for your application. Remember to consult datasheets and compare different models to find the best fit for your design.
