Introduction

Pushbutton switches are widely used in various kinds of automatic control instruments, such as military equipment, industrial machines, home appliances and automotive applications. The purpose of the pushbutton switches is to enable the users to make a selection from two or more switches. The most common type of pushbutton switch is the A3DA-90A1-00ER, which is a single pole double-throw (SPDT) switch.

Application Field

The A3DA-90A1-00ER pushbutton switch can be used in any type of device that requires a two-position switch. They are commonly used in automotive applications to control the operation of headlights, windshield wipers, door locks, and other electrical components. The switch is also used in military applications, such as controlling the frequency of fire on artillery guns. Industrial machinery, such as presses, often use the A3DA-90A1-00ER to control the timing of various operations. They are also used in many home appliances, such as refrigerators and microwaves.

Working Principle

The A3DA-90A1-00ER pushbutton switch is a two-position switch, meaning it can be switched between two states: "on" and "off." When the switch is in the "on" position, an electrical connection between two points on the circuit is established. This allows the current to flow freely in one direction. When the switch is in the "off" position, the electrical connection between the two points is broken, preventing the current from flowing.

The A3DA-90A1-00ER pushbutton switch is usually operated manually, meaning it is pushed in and out with the fingertips. When the switch is pushed in, it switches to the "on" position. When the switch is released, it switches back to the "off" position. Some models of the A3DA-90A1-00ER switch feature a locking mechanism, which prevents the switch from being randomly activated by mechanical shock or vibration. In addition, the switch can be wired to be actuated by external sources, such as an electric motor or a solenoid.

Conclusion

The A3DA-90A1-00ER pushbutton switch is a single pole double-throw (SPDT) switch that is widely used in a variety of applications, such as automotive, military, and industrial machinery. The switch is usually operated manually, but can also be wired to be activated by external sources. The switch can be used to switch between two states: "on" and "off," allowing the current to flow freely in one direction when the switch is in the "on" position and preventing the current from flowing when the switch is in the "off" position.
