In electronics and telecommunications, a crossbar switch is a collection of switches arranged in a matrix configuration. A crossbar switch has multiple input and output lines that form a crossed pattern of interconnecting lines between which a connection may be established by closing a switch located at each intersection, the elements of the matrix. Originally, a crossbar switch consisted literally of crossing metal bars that provided the input and output paths. Later implementations achieved the same switching topology in solid-state electronics. The crossbar switch is one of the principal telephone exchange architectures, together with a rotary switch, memory switch, and a crossover switch.

A handbell is a bell designed to be rung by hand. To ring a handbell, a ringer grasps the bell by its slightly flexible handle – traditionally made of leather, but often now made of plastic – and moves the arm to make the hinged clapper strike the inside of the bell. An individual handbell can be used simply as a signal to catch people's attention or summon them together, but handbells are also often heard in tuned sets.
A spillway is a structure used to provide the controlled release of water from a dam or levee downstream, typically into the riverbed of the dammed river itself.

A bell tree, also known as tree bells or Chinese bell tree, is a percussion instrument, consisting of vertically nested inverted metal bowls. The bowls, placed on a vertical rod, are arranged roughly in order of pitch. The number of bowls can vary between approximately 14 and 28. An effective glissando is produced by sliding a triangle beater, a glockenspiel mallet, or a xylophone mallet down the length of the tree. The bells are usually pitched to microtonal intervals and do not represent any formal scale. When a glissando is played, the inexactness of the order of the bowls' pitch is unnoticeable, merely creating a fuller sound.
