3. Features

• Advanced Contact Materials: Features alloy copper and palladium gold contacts for improved conductivity, stability, and long-term durability.
• Enhanced Stability: Designed with 5 pins to ensure a secure and stable connection when installed on a compatible PCB.
• LED Compatibility: Equipped with built-in LED slots and SMD compatibility, allowing for custom backlighting configurations.
• Corrosion Resistance: Utilizes electroplated copper legs and nickel-plated springs to resist corrosion and maintain performance over time.
• Smooth Actuation: The lubricated stem provides a super smooth glide, contributing to a consistent and comfortable typing experience.
• Fast Response: Small size and shorter travel distance enable faster actuation, beneficial for rapid input scenarios.
• High Durability: Engineered for a long lifespan, with an estimated durability of approximately 50 million keystrokes based on rigorous laboratory testing.

4. Setup and Installation

Kailh PG1350 Choc V1 switches are specifically designed for Choc-Compatible PCBs. They are not compatible with MX-style PCBs due to differing pin configurations. Ensure your keyboard's PCB supports Choc switches before attempting installation.

Installation Steps:

1. Prepare PCB: Ensure your keyboard's PCB is clean and ready for switch installation.
2. Align Pins: Carefully align the 5 pins of the Choc switch with the corresponding holes on the Choc-Compatible PCB.
3. Press Gently: Apply gentle, even pressure to push the switch into place until it sits flush with the PCB. Avoid excessive force to prevent bending pins.
4. Verify Connection: Visually inspect the underside of the PCB to ensure all pins are correctly inserted and soldered if necessary (for hot-swappable PCBs, soldering is not required).
5. Install Keycaps: Once switches are securely installed, attach compatible Choc keycaps.

5. Operation

Kailh PG1350 Choc V1 switches are available in three primary operational styles, each offering a distinct tactile and auditory feedback:

• Linear Switches: Provide a smooth, consistent keystroke without any tactile bump or audible click. Ideal for users who prefer a fluid and uninterrupted press. Available in Blue (20gf), Red Pro (35gf), Red (40±5gf), and Black (50gf).
• Tactile Switches: Feature a noticeable bump during the keystroke, indicating actuation without an audible click. This provides feedback to the user that the key has registered. Available in Brown (50gf) and Brunt Orange (70gf).
• Clicky Switches: Offer both a tactile bump and an audible click sound upon actuation. This provides clear feedback for each keypress. Available in White (50±10gf), Robin (47gf), and Navy (60gf).

Refer to the table below for detailed specifications of each switch type:

6. Maintenance

Proper maintenance can extend the lifespan and performance of your Kailh PG1350 Choc V1 switches.

• Regular Cleaning: Periodically remove keycaps and use compressed air to clear dust, crumbs, and debris from around and within the switches.
• Gentle Handling: When removing or installing switches, use a switch puller and apply gentle, even force to avoid bending pins or damaging the switch housing.
• Avoid Liquids: Keep liquids away from your keyboard to prevent damage to the switches and PCB. In case of a spill, immediately power off the keyboard and allow it to dry completely before use.
• Storage: Store unused switches in a clean, dry environment, preferably in their original packaging or a dedicated switch tray, to protect them from dust and physical damage.

7. Troubleshooting

If you encounter issues with your Kailh PG1350 Choc V1 switches, consider the following:

• Switch Not Registering:
  • Ensure the switch is fully seated in the PCB.
  • Check for bent pins. If a pin is bent, carefully straighten it with fine-nose pliers before reinserting.
  • Verify PCB compatibility (must be Choc-Compatible).
• Inconsistent Actuation:
  • Clean the switch thoroughly to remove any debris that might be obstructing movement.
  • Ensure the keycap is properly seated and not interfering with the switch stem.
• Physical Damage During Transport: If any switches are damaged during transportation, please notify the seller immediately for a replacement.
