Relays
Relays are electronic switches, depending on their position the one or
other (internal) connection is closed. Their mode of operation 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.
The mounting orientation of the relays which are put in a rectangular
box shaped housing is given by the layout of the pins.
Switches and push-button switches
By operating a switch or a push-button switch an electric circuit is
closed. While switches keep their status after operating (like a light
switch), push-button switches keep their operating position only as long
as actually operated (like a bell push).
Terminal strips
Terminal strips are solder-in screw-type terminals. They provide a
solder-free and safe connection of the cables to the circuit, which can
still be separated any time. When several terminal strips have to be
mounted side by side, they have to be put together before mounting.
