How to Use the Push-In Connector

Using the CMK642 push-in connector is simple and efficient. This tool-free device allows you to connect wires by inserting them directly into the terminal. Here's a step-by-step overview:

  • Prepare the Wire

Strip about 11mm (0.43 inch) of insulation from the end of the wire.

  • Insert the Wire

Push the stripped wire into the entry hole.

  • To Disconnect or Replace

Here's where the question "how to release a wire from a push-in connector" comes into play. Simply lift the orange actuating lever to release the wire - no damage, no special tool required.

This plug-and-play process makes it extremely convenient, especially in fast-paced electrical work environments or complex wiring systems where reconfiguration is frequent.

Features of the CMK642 Push-In Connector
  • Material Key Points

Shell & Lever: High-durability PA66.

Conductive Parts: Thinned copper for superior conductivity.

Contact Spring: SS301 stainless steel, ensuring a firm grip on the wire.
