Pushbutton switches are an essential part of industrial technology and essential controllers. They are used to control electric equipment, industrial automation and robotics. The pushbutton switch is a type of switch which is operated by pushing or pressing down a button and can be used for on/off, input control or sensing functions.

The pushbutton switch has evolved over the years and can now come in various shapes, colors, sizes and types. It can be a panel mount or a surface mount depending on the type of application. It can also come with a variety of contact types – normally open, normally closed, momentary, maintained, latching or break before make. Typically, a standard pushbutton switch is made up of a case, a contact, a connecting tabs and an actuator.

Pushbutton switches are used in many industries and the type of application will determine the type of switch. Some popular applications include medical, aviation and aerospace, industrial, automotive and personal electronics.

Most pushbutton switches consist of a case, a contact, a connecting tabs and an actuator. When the switch is in the ‘on’ position, the contacts inside the switch close, allowing an electrical current to flow through the contacts. When the switch is in the ‘off’ position, the contacts remain open, breaking the circuit and interrupting the electrical current. Depending on the type of switch, the contacts may be normally open, normally closed, momentary, maintained, latching or break before make.

Pushbutton switches are designed to be robust and reliable, have a long service life and are usually rated to a maximum voltage and current. They can typically operate in the temperature range of -30°C to +70°C and the contacts can be made from brass or carbon. Some switches can be equipped with a mutiple pole form in order to meet various requirements.

In conclusion, pushbutton switches are an essential part of industrial automation and are used in a multitude of applications. They work by closing or opening a circuit which sends or stops an electrical current. They can be found in various shapes, colors, sizes, contact types and materials, allowing for various control options.
