Pushbutton Switches have been used in a wide range of applications over the years, and have become increasingly important to enabling a variety of systems and technologies. The main application fields include aerospace, automotive, industrial, medical, military, printing, and telecommunications. All of these systems require some level of precision, reliability, and control in order to function properly.

The principle of push-button switches is based on the mechanical action of pushing a button. When the button is pushed, it activates a mechanism that in turn creates some form of an electrical connection. Depending on the type of switch, the connection may be completed across two contact points, or a circuit may be opened by disconnecting the contacts. The most common types of push-button switches are momentary, latching, rocker, toggle, and rotary.

Momentary switches are activated with a single press of the button, and are immediately reset once the button is released. This type of switch is commonly used for operations such as starting a timer, activating a device, or pressing an emergency control. These switches are usually straight-on action and require manual resetting.

Latching switches remain active until manually reset, making them suitable for use in applications where there is no need to constantly activate and deactivate the switch. Once the latching switch is pushed, it will stay in the on position until reset. This type of switch is often used in circuit protection and high-current systems, since they are resistant to shock and vibration.

Rocker switches are pressure activated, but the action of the switch is not a push but a rock back and forth. These switches are most commonly found in household electronics, where it may control the power, volume, or mode. When the switch is rocked back and forth, the action will either open or close the circuit.

Toggle switches are designed to operate without any spring action, which makes them ideal for low-power systems. The switch is moved from one position to another manually, and when the switch is returned to the original position, the circuit will either open or close. Toggle switches are commonly found in devices such as computers and TVs.

Rotary switches are made up of a cylindrical control shaft, which is usually connected to the center of a rotating disk. As the disk is rotated, it will make contact with different contact points, completing or breaking the circuit. These switches are most frequently used in sensitivity control applications.

Push-buttons switch applications are varied, and they have become a staple of many industrial and consumer electronics systems. Due to their precise control and reliability, they can be used in a wide range of applications and are a key component of many modern technologies.
