2P3T Slide Switch: 8 Pin 90 Degree DIP for PCB Selection

A three-position switch becomes useful when a design needs more than a simple ON/OFF or two-way selection. A 2P3T slide switch combines two independent switching poles with three selectable throw positions, allowing one actuator to control two signal paths at the same time.

The 8-pin DIP construction is suited to conventional through-hole PCB assembly, while the 90-degree orientation places the actuator in a horizontal direction relative to the PCB. This makes the configuration useful when the switch must be accessible from a product side panel, front panel or enclosure opening.

For engineers and purchasing teams, the key selection factors are not only pole and throw count. PCB orientation, pin arrangement, actuator accessibility, electrical rating, mechanical life, soldering process and enclosure geometry should all be checked before finalizing the component.

Below are the key specifications for the 2P3T slide switch with 8-pin 90-degree DIP configuration.

Electrical, mechanical, and dimensional values should be confirmed against the latest Vistar engineering drawing before PCB layout, tooling, or mass-production approval.

An 2P3T slide switch 8 pin configuration normally uses four terminals for each pole: one common terminal and three throw terminals. Two poles therefore require eight electrical terminals.

The actual pin numbering and orientation should be verified against the manufacturer’s dimensional drawing before PCB layout.

Before placing a production order, engineering and procurement teams should confirm the following points:

1. Confirm the circuit function. Make sure the design requires two poles and three throws rather than a 2P2T or 1P3T configuration.
2. Confirm the physical orientation. Check that the 90-degree actuator direction matches the enclosure and PCB edge.
3. Confirm the PCB footprint. Verify hole size, pitch, pad geometry and component keepout.
4. Confirm electrical ratings. Match voltage and current ratings to the actual load, including startup or transient conditions where applicable.
5. Confirm mechanical life. Select a switch with sufficient operating-cycle capability for the expected product lifetime.
6. Confirm assembly compatibility. Check the soldering process and PCB construction before production release.
7. Confirm environmental requirements. Review temperature, contamination, vibration and enclosure conditions.
8. Confirm supply requirements. For mass production, verify MOQ, packaging, sample availability and production lead time.

For appliance applications, engineers should also identify the applicable safety and product standards. IEC 61058-1:2026 covers general requirements for switches used in appliances and other equipment for household or similar purposes. See the current IEC 61058-1 standard for the applicable scope and requirements.

What Is a 2P3T Slide Switch?

A 2P3T slide switch is a three-position mechanical switch with two independent poles. Each pole has one common contact and three selectable contacts. Moving the actuator between the three stable positions changes which throw is connected to the corresponding common contact. This configuration allows one actuator to control two signal paths simultaneously, making it suitable for dual-channel audio routing, mode selection and multi-source signal selection.

The 8-pin DIP construction is suited to conventional through-hole PCB assembly, while the 90-degree orientation places the actuator in a horizontal direction relative to the PCB. This makes the configuration useful when the switch must be accessible from a product side panel, front panel or enclosure opening.

2P3T Slide Switch 8 Pin — Configuration and Selection

An 2P3T slide switch 8 pin configuration normally uses four terminals for each pole: one common terminal and three throw terminals. Two poles therefore require eight electrical terminals. This arrangement gives the designer two independent switching circuits operated by the same mechanical actuator.

The 2P3T configuration is particularly useful when two related signal paths must be switched together. For example, a stereo design can use the two poles to route left and right channels simultaneously between three selectable sources. The 8-pin DIP construction is suited to conventional through-hole PCB assembly, and engineers should verify the exact pin assignment against the manufacturer’s dimensional drawing before PCB layout.

8 Pin Slide Switch — PCB Signal Routing

An 8 pin slide switch is useful when two signal channels need to be selected together. The three-position configuration can provide source A, source B and source C selection, or three different operating modes depending on the circuit. Common PCB applications include three-way audio source selection, dual-channel signal routing, three-mode function selection, electronic instrument controls and test and measurement equipment.

The main advantage is simple mechanical control: one actuator changes both poles at the same time. This reduces the need for two separate switches when the two signal paths must remain synchronized.

2P3T DIP Slide Switch — Through-Hole Mounting

A 2P3T DIP slide switch is well suited to conventional through-hole PCB assembly. The terminals pass through drilled PCB holes and are soldered on the opposite side of the board. Through-hole construction can be useful for manually actuated switches because the mechanical load from sliding the actuator is transferred through the terminals and solder joints into the PCB.

Engineers should still check hole diameter, terminal pitch, component height, solder-side clearance and actuator-to-enclosure alignment before releasing the PCB layout. For comparison, Vistar also supplies SMT and other slide-switch configurations, so the correct mounting technology should be selected according to the complete PCB assembly process rather than electrical function alone.

90 Degree Slide Switch — PCB Layout and Mechanical Fit

A 90 degree slide switch is generally selected when the actuator needs to operate parallel to the PCB rather than vertically above it. This orientation is especially useful for controls accessed through the side or front of an enclosure. Engineers should check terminal pitch, hole diameter, overall switch body dimensions, actuator travel, actuator height, distance from the PCB edge, panel opening and actuator alignment before PCB release.

The electrical schematic can be correct while the mechanical design still fails if the actuator does not align with the enclosure opening. For right-angle controls, the PCB edge distance and panel geometry should therefore be reviewed together with the footprint.

Applications Across Industries

This 2P3T slide switch is widely used across multiple industries. Audio equipment uses it for three-way source selection and dual-channel signal routing. Electronic instruments use it for mode selection and configuration control. Consumer electronics use it for source, function and operating-state selection. Industrial equipment uses it for manual configuration and signal-selection functions. Communication equipment and embedded systems also rely on this 8-pin 90-degree DIP component for reliable three-position dual-pole circuit selection.
