Ideal for single wire connections that are often used for building installations. If the conductor is rigid enough, it can be connected by simply inserting it by hand without using a tool. Check the applicable wire cross-sectional area of "single wire" described in the catalog.

Use a screwdriver or a pointed object to open the connection and apply pressure to the working pushbutton. When the clamp unit opens, the conductor can be removed without damage and the pusher can be returned to its original position.

You can clearly identify the connection point by looking at the easy-to-understand orange push button. This leaves the remaining openings only for receiving the conductors. This will prevent miswiring.

The round hole next to the pusher is the test point for the tester. (The button color of the pusher is orange, white, red, or blue depending on the type of terminal block.)
