4 Position DIP Switch

The 4 Position DIP Switch (Dual In-line Package Switch) is a versatile and compact electronic component consisting of four independent single-pole single-throw (SPST) switches integrated into one small module. Each switch can be individually set to either ON or OFF, providing users with a simple and reliable way to manually configure digital circuits, hardware parameters, and operating modes without the need for software adjustments. The switch array is housed in a standard 8-pin DIP package with 2.54mm pitch, making it fully compatible with standard IC sockets, breadboards, and through-hole PCBs. DIP switches are especially useful in applications where settings must remain fixed during operation but may occasionally need to be changed—such as selecting device addresses, enabling or disabling features, setting communication baud rates, or controlling modes in embedded systems. The contacts are built using high-quality electrical materials that provide low resistance and stable performance even after thousands of switching cycles. The durable plastic body protects the internal mechanism from dust, moisture, and mechanical shock. Each switch is clearly labeled with ON markings and position numbers for easy visual identification, and can be operated using a small screwdriver, pen tip, or tweezers for precise control. Compared to the 8-position variant, this 4-position model is more compact and ideal for projects requiring fewer configuration options while saving valuable PCB space.
