Relays
Relays are electronic switches, depending on their position the one or other (internal)
connection is closed. The mode of operation of monostable relays can be compared to that of
a push-button switch, i.e. the connection is only closed as long as the voltage is applicated.
Bistable relays keep their status after switching – comparable to a switch.
Relays which combine two switches in one housing are common as well (shortly 2xUM). The
switching between the two connections can be heard clearly because of the resulting clicking
sound.
Screw terminals
Screw terminals provide a solder-free and safe connection of the cables to the circuit, which
can still be separated any time.
Terminal strips are available as single or double row versions with 2 or 3 poles (resp. 2x2 or
2x3 poles). Connections with any number of poles can be created by linking several terminal
strips. In order to fix them the connecting cables are inserted and screwed (similar to a lustre
terminal).
Plug-in units consist of a 2-, 3-, 4- or more pole box header to be soldered on the PCB and an
appropriate plug-in part into which the connecting cables have to be inserted and srewed.
