    Push Button Switches

    A push button switch is a type of electrical switch that is operated by pressing a button or plunger. It is a momentary switch, meaning that it only makes or breaks an electrical connection while the button is being pressed. When the button is released, the switch returns to its original position and the connection is broken.

    Push button switches are commonly used in various applications where manual control or signalling is required. They can be found in everyday devices such as doorbells, elevators, computer keyboards, and appliances. They are also used in industrial settings, control panels, and machinery for various purposes like starting or stopping a motor, activating an alarm, or triggering a specific action.

    Push button switches come in different designs and configurations to suit different applications. They can have different shapes, sizes, and colours, and may include additional features such as illuminated buttons or switches with multiple positions. Some push button switches have a momentary action, while others have a latching or toggle action, meaning they stay in the "on" or "off" position until pressed again.

    What are the types of push button switches?

    There are several types of push button switches available, each designed for specific purposes. Here are some common types:

    • Momentary Push Button Switch: This is the most basic type of push button switch. It is normally open (NO), meaning the circuit is open when the button is not pressed, and it closes momentarily when the button is pressed. When the button is released, the circuit opens again.
    • Latching Push Button Switch: Unlike momentary switches, latching switches have two stable positions, typically labelled as "on" and "off." Pressing the button toggles the switch between these two positions, and it remains in the selected position until pressed again.
    • Illuminated Push Button Switch: These switches feature built-in LED indicators that provide visual feedback. The LED can be lit constantly or only when the switch is in the "on" position, depending on the design. Illuminated push button switches are commonly used in applications where visual status indication is important.
    • Mushroom Push Button Switch: Mushroom switches have a large, prominent button with a rounded shape, resembling a mushroom. They are designed to be easily identifiable and pressed in emergency situations.
    • Keylock Push Button Switch: Keylock switches require a key to operate them. They offer a higher level of security by preventing unauthorized access or accidental activation.
    • Sealed Push Button Switch: Sealed switches are designed to be resistant to environmental factors such as moisture, dust, and vibration.
