2P4T Horizontal Slide Switch — SK-24D02 12 Pin DIP 4 Position PCB Mount Slide Switch for Audio, Consumer Electronics & Industrial Control

2P4T stands for “2 Pole, 4 Throw” — the standard nomenclature for describing switch circuit configurations. In the SK-24D02 2P4T horizontal slide switch:

• 2 Pole (2P): The switch simultaneously controls two independent electrical circuits. Both circuits switch together when the actuator is moved.
• 4 Throw (4T): Each pole can connect to one of four different output contacts (throws). This gives four distinct switching positions, allowing selection among four signal paths or modes per circuit.

With 12 pins total (2 poles × 4 throws + 2 common inputs), this 12 pin DIP horizontal slide switch is ideal for applications requiring multi-position mode selection in a compact form factor.

A horizontal slide switch (like the SK-24D02 slide switch 4 position) has an actuator that moves parallel to the PCB surface, with the slider knob protruding from the side of the switch body. This is ideal for low-profile designs, edge-mounted controls, and applications where the user operates the switch from the side of the product enclosure.

A vertical slide switch has an actuator that moves perpendicular to the PCB, with the knob protruding upward. Vertical switches are better suited for top-panel access and often provide a more prominent tactile target. Choose horizontal for space-constrained, thin-profile products; choose vertical for desktop equipment with top-mounted controls.

The SK-24D02 slide switch 4 position is designed for through-hole DIP mounting with the following recommended process:

<

1. Wave Soldering: The preferred method for high-volume production. Insert the 12 pins into drilled holes (typically 1.0–1.2mm diameter), apply flux, and pass through a wave solder machine. Ensure the metal shell grounding tabs (if present) are also soldered for EMI performance.
2. Hand Soldering: Suitable for prototypes and low-volume assembly. Use a temperature-controlled soldering iron at 350–380°C with Sn63/Pb37 or lead-free Sn96.5/Ag3.0/Cu0.5 solder. Solder each pin individually, ensuring complete fillet formation without bridging adjacent pins.

Standard pin spacing is 2.54mm (0.1″) pitch, compatible with standard DIP socket layouts and breadboard prototyping. For the exact hole diameter, pad layout, and keep-out zones, contact sales@vistarelectronics.com to request the official mechanical drawing.

Standard MOQ is 1,000 pieces with a 2–4 week production lead time. Free samples are available for qualified engineering and product development projects.

The 4 position slide switch 10,000 cycles detent mechanism uses an internal spring-loaded ball or plunger that engages with machined notches in the slider track. As the actuator moves between positions:

<

1. The spring compresses as the ball rides up the ramp between notches.
2. At the peak of the ramp, the spring force is maximized, creating a resisting force that prevents the switch from resting between positions.
3. As the ball drops into the next notch, the spring expands, creating a crisp “click” tactile feedback and a positive mechanical lock.

This design ensures the 2P4T horizontal slide switch cannot settle in an intermediate (half-throw) state, which would cause open circuits or intermittent connections. The detent force is calibrated to prevent accidental switching from vibration or light contact while remaining easy to actuate with a fingertip.
