Pushbutton switches such as the E221SD1AV3LE, are electromechanical devices that allow users to control a circuit by pressing a button. When the button is pressed, it breaks (or makes) a connection between two terminals and so activates an electrical circuit. As its name suggests, a pushbutton switch is actuated by pushing or pressing a button or lever.

The E221SD1AV3LE is a type of pushbutton switch that is commonly used in industrial, commercial and residential applications. It is a single pole (SPST) momentary action switch that is typically used for control applications, such as controlling the flow of electricity in a circuit.

The E221SD1AV3LE is a manually actuated switch, meaning that it requires a physical action (pushing of the button) to activate the switch. This switch is well-suited for applications where frequent operation of the switch is required, as the user can easily push the switch to activate the circuit.

The working principle of the E221SD1AV3LE is simple and straightforward. When the switch is in the off position (unpressed), there is no electrical connection between the two terminals. When the button is pressed, it forms an electrical connection between the two terminals and so activates the circuit.

Therefore, the E221SD1AV3LE is a type of pushbutton switch that is mainly used for control applications. This switch is used to control the flow of electricity in a circuit by breaking or making an electrical connection depending on the position of the button. It is a manually actuated switch that requires a physical action to activate the switch.
