Pushbutton switches are used to create an electrical connection or disconnection in a circuit. The connection is made by pushing the button by using hand, a mechanical force or another device as a trigger for the switch’s electrical connection. One of the most popular pushbutton switches is the PN22LESA03QE.

The PN22LESA03QE is a multi-voltage handheld pushbutton switch designed for use in demanding industrial and commercial applications. The switch can be used in a variety of ways, from controlling the motion of an electrical motor, to activating emergency shutdowns in hazardous conditions. It is suitable for use in the most extreme environments, and has been tested for use in wet, dry, saltwater and explosion proof applications.

The PN22LESA03QE has a rated current of up to 20A, a voltage rating of up to 690VAC, and an operating temperature of -25C to +85C. It is rated IP67 and is UL/CSA approved. It has a secure, snap-turn construction, and its contact structure is designed to reduce arcing and sparking. The switch is also resistant to shock and vibration.

The PN22LESA03QE is a versatile pushbutton switch that can be used in a variety of applications. Its main application field is in control panel systems, where it can control the start, stop or pause functions of a motor or other device. It can also be used for circuit automation, in emergency shutdown applications, or as a manual override switch in hazardous environments. It can also be used in doors and gates, as a switch for safety functions, as a e-stop switch, or in many other suitable applications.

The working principle of the PN22LESA03QE is very simple. When the user pushes the button, a spring-loaded contact is created, allowing an electrical current to flow through the switch and consequently activate the electrical device. This enables the user to control the device without having to manually wire it up. When the button is released, the spring-loaded contact is released, creating an electrical disconnection and thus deactivating the device.

The PN22LESA03QE is a reliable and versatile switch that is ideal for many industrial and commercial applications. Its rated current and voltage, along with its secure construction and ability to withstand harsh environments, make it an ideal choice for a variety of uses. Its simple operation also makes it very user-friendly, enabling users to easily control electrical devices with the push of a button.
