Opolar F401 DP3T Slide Switch – Miniature 8 Pin 3 Position Slide Switch for PCB Applications

The Opolar F401 Slide Switch is a compact and highly reliable switching component designed for modern electronic systems that require precise multi-state control. As a double pole triple throw switch, it provides the ability to control two independent circuits across three selectable positions, making it ideal for advanced signal routing, mode selection, and embedded system design.

This miniature DP3T slide switch is engineered for PCB integration, supporting high-density layouts and automated SMT or through-hole assembly processes.

Product Description

The dp3t slide switch features an 8-pin configuration that enables dual-circuit switching with three stable positions (ON-ON-ON). Unlike standard toggle switches, this 3 position slide switch allows more flexible circuit design, making it suitable for multi-function electronic devices.

With a compact body and smooth sliding actuator, the 8 pin DP3T switch ensures reliable electrical contact, low resistance, and long mechanical life even in demanding environments.

The 8 pin DP3T switch is widely used in various electronic systems, including:

• Audio equipment (stereo signal routing, effect selection)

• Guitar and musical instrument circuits

• Industrial control panels

• Embedded system mode switching

• Test and measurement instruments

• Communication devices

• Motor control systems (forward/stop/speed selection)

• DIY electronics and prototyping projects

Its flexibility makes it a preferred 3 position slide switch for engineers and product designers.

FAQ

Q1: What is a DP3T slide switch used for?
A dp3t slide switch is used for controlling two independent circuits across three selectable positions, commonly used in signal routing and mode selection.

Q2: What does 8 pin DP3T switch mean?
It refers to a switch with 8 terminals that supports dual-pole, triple-throw functionality for more complex circuit designs.

Q3: Is this a momentary switch?
No, this is a latching 3 position slide switch, meaning it stays in each selected position until manually moved.

Q4: Can it be mounted on a PCB?
Yes, it is designed specifically as a miniature DP3T slide switch for PCB mounting and automated assembly.

Q5: What is the difference between DPDT and DP3T?
A DPDT switch has two positions per pole, while a double pole triple throw switch provides three positions, allowing more circuit control options.
