Pushbutton switches are used in a variety of applications, from the low-end momentary contact switches to the high-end programmable logic controllers. The KFB2DNA1BBB is a pushbutton switch that is part of the KFB2 series of pushbutton switches from Siemens. It is a spring-return pushbutton switch that uses three momentary contact push buttons. The KFB2DNA1BBB has a single actuator with an adjustable dead-band to give it a long life and reliable operation. The operating temperature range of the KFB2DNA1BBB is -40° C to +70° C.

The KFB2DNA1BBB is designed for use in industrial control and automation applications such as pushbutton machinery start and stop control, pull-to-release and return-to-start applications, as well as other applications where reliable, high-integrity momentary contact pushbutton switches are required. Common applications include elevator control, industrial door and gate control, machine tool and other machine controller functions, HVAC and process control, access control systems, and switching of lighting, motors, and power.

The KFB2DNA1BBB features three pushbuttons mounted in the same housing. When any one of the pushbuttons is pressed, the contact is made within the switch and the actuator is driven forward. When the button is released, the switch returns to its starting position due to its internal spring-return mechanism. The adjustable dead-band within the switch controls the amount of return travel and allows the switch to return to its starting position reliably, even if the travel distance is slight or the actuation force is slight. This ensures reliable operation of the switch in all applications.

The KFB2DNA1BBB is a good choice for a variety of switching and control applications where reliability and long life are paramount. The adjustable dead-band ensures that the switch will perform reliably for a long time, making it the ideal choice for applications that require high-integrity momentary contact pushbuttons. The KFB2DNA1BBB is a reliable, long-life pushbutton switch that is suitable for a wide range of industrial, commercial, and residential applications.
