These terminal blocks have levers that when operated with a fingernail or small object cause inserted wires to be gripped or released enabling easy, temporary connections to a PCB.

Various sizes are available. 

They are physically moulded together in the number of ways selected, that is to say a 2 way strip has 2 terminals moulded together a 3 has 3 etc. etc. However each individual terminal in the strip is electrically separate from the next, the idea is that the strip is soldered on to a PCB and then a speedy connection can be made to each terminal by inserting a separate bared wire and pulling down the white lever to make each individual connection.

Thumb grip lever – pull down to lock on wire, lift to release
