  • noun . In electricity, a device for opening or closing an electric circuit, for reversing the direction of the current in such a circuit, for shifting current from one branch of a circuit to another, or, in general, for making, breaking, or shifting electrical connections. Switches vary greatly in design according to the conditions to be met. In general a switch differs from a key (which is a device for the easy and rapid making or breaking of a circuit, as in telegraphic signaling) in that it is so constructed that the circuit when broken shall remain open and when made shall remain closed until the reverse operation is performed. A switch should be so constructed as to carry permanently without excessive heating the maximum eurrent of the circuit in which it is placed, and the contacts should be of such low resistance that they will not become appreciably hot on the passage of the current. Good contact is sometimes secured by the use of a ‘mercury-switch’ in which the terminals of the lines to be connected are permanently attached to metallic capsules filled with mercury. When the circuit is to be closed connection between the mercury-cups is made by means of a short copper bar or link with ends bent downward so as to dip into the mercury. The volatilization of the mercury by the spark formed when the circuit is opened is a serious objection to mercury-switches and the ‘knife-switch’ is therefore more frequently used. It consists of a strip of copper, the knife, hinged at one end, or sometimes of two or more such knives mounted parallel to one another. The free end of the knife enters with considerable friction between the jaws of a copper clip when the circuit is to be closed, the friction serving to secure good contact between the metallic surfaces and to bold the knife in place. On high-tension circuits various devices are employed to prevent the formation of an arc when the circuit is open or to extinguish the arc when formed. One such device is the ‘snap-switch,’ in which, in order to make contact, a powerful spring is compressed and the switch is locked by a simple mechanism. When unlocked, the spring opens the switch with great suddenness, and the arc is of short duration. Sometimes a magnetic blow-out is used to extinguish the arc and sometimes an ‘oil-break switch’ is employed in which the opening of the circuit is made under oil. Automatic switches are frequently used in connection with electrical machinery. In the case of such switches the operation, whether it consist of the opening or closing of a circuit, the reversal of current, or the shifting of connections from one circuit to another, is done mechanically, either by the direct action of electromagnets or by mechanism released and set in motion by such magnets or otherwise.
