1825042-5

The 1825042-5 series of pushbutton switches provide a direct current (DC) electrical connection when pressed. This design is useful in a variety of applications due to its low required voltage, small form factor, and long operating life. Several configurations and contact styles are available depending on the user\'s specific needs.

Components

The 1825042-5 series of pushbutton switches consists of three primary components – a button, switch and cover. The button, or actuator, is what the user presses to make contact. The switch is the internals which make the electrical connection when the button is pressed, and the cover is the external plastic shell which houses the other two components. Depending on the specific model, some components may be integrated and others an optional accessory.

Basic function

When the actuator is pressed, the switch mechanism internally creates a switch closure between two terminals, establishing an electrical connection. Depending on the specific model, the connection can be momentary, meaning the connection is only established as long as the button is held down, or it can be latching, meaning the connection is kept until the actuator is pressed again.Some models may also feature multiple terminals, which can be used for multiple circuits or to control multiple states.

Mounting & installation

The 1825042-5 series of switches can be installed several ways, such as surface mounting, through hole/panel mounting, or by using mounting screws and brackets (optional). The recommended mounting height is 4.5 mm to 12.7 mm (0.18" - 0.50").

Applications

The 1825042-5 series of pushbutton switches are widely used in a variety of applications due to their durability and user-friendliness. This includes applications like lighting control, motor control, HVAC, industrial machinery, and audio/visual equipment.

Working principle

When the actuator is pressed, it pushes the inner switch mechanism and closes the connection between the terminals. This creates a small electrical current, which is used to signal the connected device. Depending on the type of switch, the current can either latch or be momentary. In some instances, multiple terminals can also be used to control different states or separate circuits.

Conclusion

The 1825042-5 series of pushbutton switches are ideal for a variety of applications due to their small form factor, low voltage requirements and durable construction. These switches offer users complete control of their circuits and provide the convenience of either momentary or latching contacts. In addition, multiple terminals can be used to create multiple states and additional control options.
