The BD09BU is a DIP (Dual In-line Package) switch manufactured by C&K Components. DIP switches are used for configuring electronic devices by allowing users to set a series of on/off switches. The BD09BU contains 9 individual switches, each of which can be independently set to control various functions or represent a binary code within a circuit.

Applications

• Configuration of settings on printed circuit boards (PCBs).
• Selection of operating modes in electronic devices.
• Setting addresses for interconnected devices in network systems.
• Calibration of electronic test and measurement equipment.
• Programming of embedded systems and microcontrollers.

Features

• 9 individual SPST (Single Pole Single Throw) switches in a single package.
• Standard DIP package for easy insertion and soldering on PCBs.
• Recessed actuator design to minimize accidental switching.
• Gold-plated contacts to ensure reliable and low-resistance switching.
• Sealed construction providing protection from dust and other contaminants.

Benefits

• Provides a straightforward method for configuring electronic devices.
• Ensures reliable switching performance over its operational life.
• Reduces the likelihood of inadvertent setting changes.
• Offers long-term performance in various environmental conditions.
• Delivers a cost-effective solution for device configuration requirements.

Specifications

The BD09BU DIP switch includes 9 SPST switches typically rated for 24VDC at 25mA. Contact resistance is usually less than 50 milliohms. It operates within a temperature range of approximately -20°C to +85°C. The design is for through-hole mounting onto PCBs. The actuator type is typically a recessed slide to prevent accidental operation. The materials used comply with RoHS standards.
