The Miniature DPDT Slide Switch is a compact and versatile component designed for precision control in electronic circuits. Here are its key features with technical specifications:
1. Dual-Pole Dual-Throw (DPDT) Configuration: This switch features two independent circuits (poles) with two positions each (throws), enabling simultaneous control of two separate signal paths. Its contact rating is typically 3A at 125VAC or 1.5A at 250VAC, making it suitable for low-power applications.
2. Compact Dimensions: With a standard footprint of 6.5mm × 10mm × 4.3mm (L×W×H), the miniature design saves PCB space while maintaining robust performance. The slide actuator travel distance is precisely engineered at 2.5±0.2mm for reliable switching.
3. High Reliability: Constructed with phosphor bronze contacts and silver plating, the switch offers low contact resistance (<30mω initial="">) and withstands 10,000+ mechanical cycles. The operating temperature range spans -20°C to +85°C for diverse environments.
4. Precise Actuation: The slide mechanism requires an operating force of 200±50gf, ensuring positive tactile feedback. The gold-plated terminals provide excellent solderability with 260°C wave soldering compatibility for 10 seconds maximum.
5. Versatile Mounting Options: Available in both through-hole (THT) and surface-mount (SMD) variants. The THT version features 0.5mm diameter leads with 2.54mm pitch, while SMD types comply with J-STD-020 moisture sensitivity standards.
6. Electrical Isolation: The switch provides 500VAC insulation resistance between contacts for 1 minute, with dielectric strength exceeding 100MΩ at 500VDC. This ensures safe operation in circuits requiring signal separation.
The DPDT Slide Switch works by physically sliding a lever to change the connection between the input and output terminals. The sliding mechanism moves a conductive contact inside the switch housing, bridging the appropriate terminals to complete or break the circuit.
In the ON-ON configuration, sliding the lever connects each input terminal to one of two output terminals.
In the ON-OFF-ON configuration, there is an additional neutral (OFF) position where no connection is made between input and output terminals.
The movement of the slider ensures a secure and tactile engagement with the internal contacts, providing reliable operation across multiple switching cycles.
1.Reversing Polarity: In motor control applications, DPDT switches are used to reverse the polarity of the motor's power supply, enabling forward and reverse motion.
2.Circuit Selection Allows users to toggle between two sets of circuits for dual functionality.
3.Power Switching: Provides control over two independent power supplies or loads.
4.Mode Switching: Used to alternate between different operating modes in electronic devices.
5.Signal Routing: Directs audio, video, or data signals between different inputs or outputs.
1.Industrial Automation: Control panels for selecting operational states or routing signals.
2.Robotics: Reversing motor polarity for direction control.
3.Telecommunications: Switching between communication channels or circuits.
4.Lighting Systems: Managing multiple lighting circuits in architectural or automotive applications.
5.Consumer Electronics: Mode selection in audio equipment, handheld devices, and home appliances.
6.Testing and Prototyping: Used in test setups to select or route signals and power.
7.Model Railroads: Switching tracks or controlling train direction
