Push-in spring connection
Terminals using the push-in connection technology work on the pressure spring princi-
ple:
The contact spring presses the cable against the conducting copper bar. The special
spring profile allows direct and tool-free wiring of solid and flexible cables previously as-
sembled with ferrule or compressed conductor ends (0.25 mm² or greater).
▶
When the cable is inserted into the
clamping unit the spring opens auto-
matically.
▶
In order to loosen the conductor or
connect smaller ones with a cross-
section of 0.14 mm² or greater, you
must press the push button of con-
trasting color using a slot screwdriver.
