A22EL-M-T2-01 Pushbutton Switches - Application Field and Working Principle

The A22EL-M-T2-01 pushbutton switch is a highly versatile device that can be used in numerous applications. It is a self-contained family of switches, consisting of mechanical and electronic parts that act as a single unit. The switch is widely used in automotive, industrial, and consumer electronics applications.

Mechanical Pushbuttons

The mechanical switch element is typically composed of a rotary cam, a plunger and a series of contacts. When the plunger is pressed, it rotates the cam and the cam actuates the circuit switch contacts. The plunger can be actuated either by a simple press or by a rotary motion such as turning a knob. The plunger can also be actuated by a momentary pushbutton or by a toggle action switch. In all of these designs, the plunger is the main switch actuating element. The contacts for the switch can be single pole or dual pole and can be either normally open (NO) or normally closed (NC). These switches can be wired in different configurations. For example, two normally closed switches can be wired in series or two normally open switches can be wired in parallel. The mechanical switch element is typically enclosed in a plastic housing. The housing is typically molded in one piece and can be mounted onto a variety of surfaces using mounting screws or spacing standoffs for surface mounting applications.

Electronic Switch Components

The electronic switch elements of the A22EL-M-T2-01 are typically comprised of a diode, a transistor and a capacitor. The diode is used to pass current in either direction, while the transistor and the capacitor act together to amplify and synchronize the electrical signal. The diode and the transistor are usually surface mounted (SMT) components. The capacitor can either be a polarized or non-polarized device and is housed in a through hole mounting design. The electrical switching elements can be configured in a variety of ways. For example, a single transistor can be wired as a normally open or a normally closed switch, or two transistors can be wired as a bi-stable switch. This helps to increase the versatility of the A22EL-M-T2-01 for different applications.

Working Principle of the A22EL-M-T2-01

The working principle of the A22EL-M-T2-01 is based on the mechanical switch element and the electronic switch components. When the plunger is pressed, the cam rotates and the series of contacts are actuated. This actuation of the contacts creates an electric signal that is amplified and synchronized by the diode, transistor, and capacitor. The electric signal can then be used to control the flow of current to various parts of a circuit, such as controlling the flow of power to a motor, activating a solenoid, or lighting up an LED. This makes the A22EL-M-T2-01 a very versatile and reliable switch that can be used in a wide variety of applications.

Conclusion

The A22EL-M-T2-01 is a highly versatile pushbutton switch. It combines mechanical and electronic components to provide a reliable and robust switching solution for many types of applications. The mechanical switch element actuates the series of contacts to generate an electrical signal that is then amplified and synchronized by the electronic switch components. This signal can then be used to control the flow of current in a circuit.
