Pushbutton Switches
Pushbutton switches are probably one of the most commonly used electrical components. They are usually made up of a lightweight metal contact pieces, such as a silver or copper alloy, suitably encased in a hard plastic. The contacts of the switch are insulated from one another, preventing current from flowing between them, until the button is pressed. This activates two spring-loaded components which in turn bridge the contacts to enable current to flow from one to the other. When the button is released, the current flow ceases as the contacts separate once more.
3489 application field and working principle
The 3489 can be used for a number of different applications. These include high current applications such as water systems or household appliances, or low current applications such as a computer or other digital device. The number of underlying principles of operation is relatively small. Generally speaking, when the switch is pushed, the contacts are connected, allowing current to flow. When the switch is released, the contacts separate again and the current is interrupted.In some instances, the switch may be used to open or close more than one circuit at the same time. Multiple connections with a single switch may include numerous contact configurations that involve different circuits. Examples of these are known as single pole double throw (SPDT), double pole double throw (DPDT) or four position switches.
Different types of Pushbutton Switches
These electrical components are often segregated by the type of contact required to complete the circuit. The four primary contact types for pushbutton switches are: normally open (NO) contact, normally closed (NC) contact, single-pole double-throw (SPDT) contact and double-pole double-throw (DPDT). A normally open contact requires a push of the switch and then the connection is made. With a normally closed contact, the connection is already made and releasing the switch opens the circuit.
The SPDT is a single switch that can open and close two different circuits. When the switch is pushed, the connection is closed to one circuit, while the connection is opened on the other circuit. The more advanced DPDT switch offers two switches, each opening and closing two circuits at the same time. While both switches are pushed in the same direction (open or closed) they will control four independent circuits.
General Consideration
The size and shape of pushbutton switches vary with the application. While larger buttons are easier to use and press, they take up additional space on a crowded circuit board. Smaller components are better suited for tight fits around the other items with which they must be integrated. Likewise, selecting the proper rating for the switch is essential to ensure its proper function.
Apart from these considerations, two particularly important attributes of the switch choice must be taken into account. First, the electrical rating of the switch is important to ensure that the proper voltage or current is not exceeded. Second, the mechanical rating of the switch is important to guarantee the switch functions correctly in extreme environmental conditions. This includes humidity, temperature, dust, vibration, shock and ionization.
