What Is a 1P3T Horizontal Slide Switch?
A 1P3T horizontal slide switch (Single Pole Triple Throw) is an electromechanical switch that connects one common terminal to one of three output terminals depending on the slider position. Unlike more common SPDT (1P2T) switches, this 1P3T slide switch provides three distinct circuit paths, making it ideal for mode selection, input source switching, and multi‑range settings. The horizontal actuator moves parallel to the PCB surface, which is optimal for front‑panel or side‑panel mounting where the user pushes the switch from the enclosure edge. With a 4‑pin DIP footprint and standard 2.54mm pin pitch, this 4 pin slide switch is directly compatible with prototyping breadboards and automated through‑hole assembly lines.

How Does a 1P3T Slide Switch Work?
Inside a 3 position slide switch, a sliding contact wiper moves along a stationary contact strip with four terminals: one common and three outputs. The common pin is typically located at one end of the row, with the three position pins arranged alongside. When the actuator is in position 1, the common connects to output 1; sliding to position 2 connects to output 2; and position 3 routes the common to output 3. Each position has a positive detent that holds the slider firmly in place, preventing accidental mid‑position settling. This purely mechanical design requires no power to maintain any state, and the gold‑plated contacts ensure stable, low‑resistance switching over the entire 10,000‑cycle lifetime. Engineers choose a 1P3T horizontal slide switch when they need a simple, visible, and reliable way to select among three circuit options without adding relays or digital multiplexers.
Key Features of the 4 Pin DIP Slide Switch
Three‑Position Selection
One common terminal routes to three independent outputs, providing flexible mode or source selection in a single compact component.
Horizontal PCB Mounting
Side‑actuated design enables front‑panel operation, saving vertical space and simplifying enclosure design.
DIP Through‑Hole Terminals
Four pins soldered through the board provide robust mechanical anchoring that withstands repeated actuation forces.
Stable Electrical Contact
Gold‑plated phosphor bronze contacts maintain ≤50mΩ resistance across the full 10,000‑cycle life.
10,000‑Cycle Mechanical Life
Designed and tested for over 10,000 operations, ensuring years of reliable service in frequently adjusted equipment.
RoHS & REACH Compliant
Meets global environmental standards. See RoHS Compliance Guide.

Applications of 1P3T Horizontal Slide Switches
Function selectors on set‑top boxes, remote controls, and smart home devices where a horizontal slide switch provides intuitive multi‑mode control.
Input source selection, filter toggling, and equalisation presets in mixing consoles and Hi‑Fi systems.
Channel selection and band switching on two‑way radios and transceivers.
Mode selection and speed setting on motor drives, PLCs, and automation panels requiring a PCB slide switch with clear visual position indication.
Range switching and function selection on test and measurement equipment.
Configuration and boot mode selection on development boards and single‑board computers.

1P3T Horizontal vs Vertical Slide Switch – Choosing the Right Orientation
When integrating a 1P3T slide switch into a product, the actuator orientation significantly impacts enclosure design and user experience. The table below compares horizontal and vertical mounting options:
| Feature | Horizontal Slide Switch | Vertical Slide Switch |
|---|---|---|
| Actuator Direction | Parallel to PCB (side push) | Perpendicular to PCB (top push) |
| Typical Use | Front‑panel, side‑panel access | Top‑panel, internal configuration |
| PCB Space | Narrower along board edge | More compact footprint |
| Enclosure Design | Slot in side wall | Slot in top cover |
If your PCB requires an upright actuator for top‑panel access, explore our Vertical Slide Switch series.
How to Select a Horizontal Slide Switch for Your PCB
Choosing the correct horizontal slide switch involves matching the electrical and mechanical requirements of your design. Key selection criteria include:
- Number of Poles: A 1P3T (single pole) switch controls one circuit among three positions. For applications requiring simultaneous switching of two independent circuits, consider a DPDT horizontal slide switch like our DPDT 6 Pin Slide Switch.
- Number of Positions: This 3 position slide switch offers three distinct outputs. If you only need two positions (ON‑ON), an SPDT horizontal slide switch such as our SPDT 3 Pin DIP Horizontal may be more appropriate.
- Current Rating: The SS-1P3T is rated for 0.5A at 50V DC, suitable for most signal‑level and low‑power control circuits.
- PCB Space: The 4‑pin DIP footprint with 2.54mm pitch fits standard layouts. For space‑constrained designs, verify the actuator travel clearance.
- Mounting Style: Through‑hole DIP provides superior mechanical strength; SMT versions are available for automated assembly.

Frequently Asked Questions – 1P3T Horizontal Slide Switch
What is a 1P3T slide switch?
A 1P3T slide switch has one pole (single common terminal) and three throws (output positions), allowing the user to select among three circuit paths. The SS-1P3T is a 4‑pin DIP horizontal version.
What is the difference between 1P2T and 1P3T?
1P2T (SPDT) switches between two outputs; 1P3T adds a third position, providing three selectable circuits. This is useful for mode selection or multi‑range settings.
What is a horizontal slide switch used for?
Horizontal slide switches are used for front‑panel or side‑panel controls where the user pushes the actuator from the enclosure edge. They are common in consumer electronics, audio equipment, and industrial panels.
Can a 1P3T slide switch be used for signal selection?
Yes. The gold‑plated contacts provide stable, low‑resistance switching suitable for audio, data, and control signal routing.
Is a DIP slide switch suitable for industrial applications?
Yes. The through‑hole DIP construction provides robust mechanical anchoring and reliable performance, making it suitable for industrial control and instrumentation.
