Pushbutton switches are ubiquitous components of most electronic and mechanical systems. They come in a variety of sizes, shapes and forms, but they all provide essentially the same function: to enable or disable the flow of energy through two conductive surfaces.

The 1241.6611.1110000 application field and working principle of pushbutton switches are quite straightforward. When the switch is off, no current flows through the switch contacts, blocking the flow of power to the device or system connected to it. When the switch is on, current flows through the switch, enabling power to flow to the device or system.

The most common types of pushbutton switches are the single-pole single-throw (SPST) and the double-pole double-throw (DPST). The SPST switch has two connections, one for the common terminal and one for the switched terminal. When the switch is pressed, the two terminals are connected together and power flows to the device or system. The DPST switch has four connections: two for the common terminals and two for the switched terminals. When the switch is pressed, two sets of connections are made, allowing power to flow to two independent devices or systems.

The working principle of a pushbutton switch is simple. When the switch is pressed, a metal rod inside the switch is pushed down, engaging a switch contact which closes the circuit. When the switch is released, the metal rod pops back up, disengaging the switch contact and opening the circuit. The majority of switches are spring-loaded, ensuring they snap back to their original position as soon as they are released.

In addition to the basic SPST and DPST switches, there are numerous other types of pushbutton switches available. These include miniature, waterproof, momentary and illuminated versions. Furthermore, the switches can be latching or non-latching. In a latching switch, when the button is pressed, the switch stays in the “on” position until it is manually switched off, while a non-latching switch turns off automatically once the button is released.

Pushbutton switches are some of the oldest and most reliable components used in modern electronics. They can be used in a variety of applications from opening doors to remotely activating machinery. With their simple working principle and wide range of available styles and functions, pushbutton switches are a useful and reliable means of controlling and monitoring the flow of power.
