Push-in spring-cage technology

The push-in leg-spring connection method enables quick and tool-free conductor connection.




The solid conductor or a fine-stranded conductor with ferrule is simply inserted in the terminal point and pressed against the current bar by the leg spring.

It is only when fine-stranded conductors without ferrules are connected and when this connection is released that it is necessary to actuate the opening lever, which is a feature of these terminal blocks.

The push-in spring combines the advantages of the leg spring with those of spring-cage technology, thus enabling conductor connection without additional tools by means of the direct plug-in method.

In addition, the fixed, predefined cage of the combined springs prevents the conductor from slipping sideways.

The push-in spring therefore enables, in particular, the tool-free connection of large conductor cross-sections with moderate force.




Customer benefits

  • Fast connection thanks to the tool-free direct plug-in method
  • User-friendly thanks to the protection against operating errors
  • Large conductor cross-sections can be connected with moderate force

One area of application is compact device connection of large conductor cross-sections for fast wiring in the field.


Push-lock spring-cage technology


The push-lock spring enables easy and tool-free conductor connection with or without ferrules by means of the one-hand tilting lever principle.

Simply insert the solid or stranded conductor in the open terminal point and connect it securely by actuating the tilting lever via the push-lock spring.

Alternatively, conductors can also be inserted directly when the lever is closed by means of the push-in method.

Customer benefits

  • Quick and easy connection by means of the one-hand tilting lever principle or direct plug-in method
  • No conductor pretreatment required
  • Intuitive operation thanks to color-coded actuating lever
  • Tool-free

Fast and easy-maintenance connection method for the internal wiring of electronic devices and in the field.
