| Socket. You can put round and tall light bulbs into this element. Place up to five sockets in the simulation window. With the Select tool, you can move and rotate sockets, and wire them to other objects. You attach wires to the socket's two nodes (see the tall bulb in socket for the locations of these nodes). To put light bulbs into the socket, move the bulb toward the socket from above (Figure 1). When a red square starts flashing on the socket (Figure 2), release the bulb (i.e., release the mouse button). The bulb combines with the socket automatically (Figure 3).

You can remove the bulb from the socket by just clicking on the bulb and dragging it upward. If you have five tall bulbs in sockets, you cannot combine any more tall bulbs with sockets. If you have five tall bulbs out of sockets, you cannot pull any tall bulbs from sockets. The same limitations apply to round bulbs.
