In this article, we will discuss how to install a lift push button on a cargo lift, focusing on the popular LA38 switches. By following this guide, you can ensure that your cargo lift operates smoothly and safely.

Materials and Tools Required

Before beginning the installation process, gather the necessary materials and tools:

1. Lift push button (LA38 switch or similar)
2. Screwdriver
3. Wire stripper
4. Electrical tape
5. Multimeter (optional)

Step-by-Step Guide to Installing a Pushbutton Switch on a Cargo Lift

Step 1: Choose the Appropriate Lift Push Button

Select a suitable pushbutton switch for your cargo lift. The LA38 switches are a popular choice because of their durability and reliability. Ensure that the switch is compatible with your cargo lift’s control system and electrical requirements.

Step 2: Turn Off the Power Supply

Before beginning the installation process, ensure that the power supply to the cargo lift is switched off. This will protect you from potential electrical hazards during the installation.

Step 3: Remove the Old Pushbutton Switch (if applicable)

If you are replacing an existing pushbutton switch, first remove the old switch from the control panel. Unscrew and disconnect any wires that are connected to the switch. Take note of the wire connections, as you will need to replicate these connections when installing the new switch.

Step 4: Install the New Pushbutton Switch

Insert the new lift push button (e.g., LA38 switch) into the control panel. Ensure that the switch is securely fastened, and the button is facing outward for easy access.

Step 5: Connect the Wires

Using the wire stripper, strip the ends of the wires that will be connected to the new pushbutton switch. Refer to the wiring diagram provided with the switch or the notes you took when removing the old switch. Connect the wires to the appropriate terminals on the new switch. Ensure that the connections are secure and properly insulated with electrical tape to prevent short circuits or other electrical issues.

Step 6: Test the Pushbutton Switch

Once the new lift push button is installed and the wires are connected, it’s time to test the switch’s functionality. Turn the power supply back on and press the button to verify that the cargo lift responds as expected. If the lift does not operate correctly, double-check your wiring connections and consult the lift’s manual or a professional technician for assistance.

Step 7: Secure the Control Panel

After confirming that the pushbutton switch is functioning correctly, reassemble and secure the control panel. Ensure that all components are properly fastened and that the panel is closed tightly to prevent dust, debris, or moisture from entering the control system.


Installing a new pushbutton switch, such as the LA38 switches, on a cargo lift is a straightforward process that can be accomplished with the right tools and some basic electrical knowledge. By following the steps outlined in this guide, you can ensure that your cargo lift operates smoothly, safely, and efficiently. Remember to always consult your lift’s manual or a professional technician if you encounter any difficulties or have questions about the installation process.
