Pushbutton Switches

UB15NBKG015F-FB is a tactile pushbutton switch, which is typically used for selecting options or for a confirmation that a choice is actually made.

Application Field

UB15NBKG015F-FB has a wide range of applications, such as providing control mechanism in a variety of electronic products, displaying the settings and selections in the avionics system, and activating certain functions in the industrial machinery.

This type of switch can also be used in the home appliances. For example, it can be used to control the power switch, oven temperature, ventilation fan, and so on, so that users can conveniently adjust settings to achieve their needs.

Working Principle

UB15NBKG015F-FB switch is constructed with a metal dome, a press button, and a plunger. When the press button is depressed, it pushes the plunger which then moves down and causes the metal dome to open.

The metal dome is made up of a metallic plate with small bumps on it. When the plunger\'s movement is blocked by the external force, it will compress the metal dome and cause the bumps to come into contact with each other, generating a conductive path across the pins. When the force is removed, the plunger will move back to its original position, and the bumps’ contact will be released.

The advantage of using this structure is that it offers the best tactile feedback, allowing users to feel the actual “clicking” of the switch. Moreover, due to the robust mechanical structure, this type of switch is widely used in extreme environmental conditions.
