Archimedes' principle

Archimedes' principle (also spelled Archimedes's principle) states that the upward buoyant force that is exerted on a body immersed in a fluid, whether fully or partially, is equal to the weight of the fluid that the body displaces.

See Mercury relay and Archimedes' principle

Armature (electrical)

In electrical engineering, the armature is the winding (or set of windings) of an electric machine which carries alternating current.

See Mercury relay and Armature (electrical)

A contactor is an electrically controlled switch used for switching an electrical power circuit. Mercury relay and contactor are relays.

See Mercury relay and Contactor

Displacement (fluid)

In fluid mechanics, displacement occurs when an object is largely immersed in a fluid, pushing it out of the way and taking its place.

See Mercury relay and Displacement (fluid)

Magnet

A magnet is a material or object that produces a magnetic field.

See Mercury relay and Magnet

Magnetism

Magnetism is the class of physical attributes that occur through a magnetic field, which allows objects to attract or repel each other.

See Mercury relay and Magnetism

Mercury (element)

Mercury is a chemical element; it has symbol Hg and atomic number 80.

See Mercury relay and Mercury (element)

Mercury poisoning

Mercury poisoning is a type of metal poisoning due to exposure to mercury. Mercury relay and mercury poisoning are mercury (element).

See Mercury relay and Mercury poisoning

Mercury switch

A mercury switch is an electrical switch that opens and closes a circuit when a small amount of the liquid metal mercury connects metal electrodes to close the circuit. Mercury relay and mercury switch are mercury (element).

See Mercury relay and Mercury switch

Power factor

In electrical engineering, the power factor of an AC power system is defined as the ratio of the real power absorbed by the load to the apparent power flowing in the circuit.

See Mercury relay and Power factor

Reed relay

A reed relay is a type of relay that uses an electromagnet to control one or more reed switches. Mercury relay and reed relay are relays.

Relay

A relay Electromechanical relay schematic showing a control coil, four pairs of normally open and one pair of normally closed contacts An automotive-style miniature relay with the dust cover taken off A relay is an electrically operated switch. Mercury relay and relay are relays.

Solenoid

An illustration of a solenoid Magnetic field created by a seven-loop solenoid (cross-sectional view) described using field lines A solenoid is a type of electromagnet formed by a helical coil of wire whose length is substantially greater than its diameter, which generates a controlled magnetic field.

See Mercury relay and Solenoid

Solid-state relay

Solid state contactor PCB mount solid-state DIL relay A solid state relay (SSR) is an electronic switching device that switches on or off when an external voltage (AC or DC) is applied across its control terminals. Mercury relay and solid-state relay are relays.

See Mercury relay and Solid-state relay

Switch

In electrical engineering, a switch is an electrical component that can disconnect or connect the conducting path in an electrical circuit, interrupting the electric current or diverting it from one conductor to another.
