🧩 Understanding the Telemecanique XB4 Push Button Components

Before assembling your push button, it helps to understand the core elements. Every Telemecanique XB4 button typically consists of:

Core Component Parts:

• Actuator / Button Head

  • Flush Push Buttons:

    • ZB4BA1 (White)

    • ZB4BA2 (Black)

    • ZB4BA4 (Red)

    • ZB4BA5 (Yellow)

    • ZB4BA6 (Blue)

    • ZB4BA8 (Grey)

  • E-stop Button: ZB4BS844

  • Selector Switches: ZB4BD2, ZB4BD3

  • 2-Position Selector (Removable both positions): ZB4BG4

• Carrier / Mounting Collar

  • Example: ZB4BZ009

• Contact Blocks

  • Normally Open (NO): ZBE101

  • Normally Closed (NC): ZBE102

These modular parts allow for full flexibility in configuring your push button control systems.

🔧 How to Assemble a Telemecanique XB4 Push Button

You’ll need:

• 1x Button head (actuator)

• 1x Carrier (mounting collar)

• 1x or more Contact blocks (NO/NC as required)

Step-by-Step Assembly Instructions:

1. Attach the Button to the Carrier

• Look for the arrow on the side of the actuator (button head) — it should be pointing downward.

• Align this with the upward arrow on the front of the carrier.

• Slide the button into the carrier until it clicks securely into place.

2. Install the Contact Blocks

• Turn the carrier around to access the rear. You'll notice one side is slightly raised—this helps orient the contacts.

• Take your contact block (ZBE101 or ZBE102) and align:

  • The plastic lip on the contact with the higher side of the carrier.

  • The metal connector on the contact with the indentations on the carrier.

• Push the contact block into position. You can insert up to three contacts side-by-side, and even stack them vertically using the appropriate mounting configuration.

✔️ Once the contacts are attached, your Telemecanique XB4 push button is ready to install in your control panel.

🔄 How to Disassemble a Telemecanique XB4 Push Button

Need to change contacts or replace a button? Here's how to safely take it apart.

Step-by-Step Disassembly Instructions:

1. Remove the Contact Blocks

• Locate the arrow on the back of the carrier, near the contact area.

• Insert a flat-head screwdriver under the contact block where it clips onto the carrier.

• Gently pry the contact off—it should come away with minimal force.

2. Release the Button Head

• On the right-hand side of the carrier (looking at it from the front), you’ll find a metal release lever.

• Pull this lever outwards to disengage the actuator from the carrier.

• Slide the button head out.

✔️ Your push button is now fully disassembled and ready for maintenance, reconfiguration, or replacement.
