An electrical switch used within an electrical system to control the on/off state of a device. A contactor is generally operated by an electromagnetic coil.
An alarm unit used in cable pressurization schemes which activates when there is a fall in pressure. Also a large mechanical relay used to open or close electrical circuits.
One or more sets of contacts that are opened or closed by a magnetic coil. The contactor is similar to a relay but normally larger. By definition, the contactor is rated for more than 15 A.
In model railroading, a switch-like device that fits beneath a section of toy train track, and is activated by the weight of a train passing over it.
A device for the purpose of repeatedly establishing or interrupting an electric power circuit. A heavy duty relay used to control electrical circuits. Relays rated at 15 to 30 amps and up are generally referred to as contactors.
A special relay for switching heavy currents at power line voltages.
A two-state (on or off) device for making and breaking an electric power circuit.
a device (similiar to a relay) that can switch one or more circuits off and on by having voltage applied to a completely different circuit
a large relay, usually used to switch current to an electric motor or other highpower load
an electrical Electricity is a property of certain subatomic particles (e
an electrical switch that uses a low power signal to turn the high power signal off and on
a type of relay designed for high-current applications
a very heavy-duty relay used for switching electric motors and lighting loads
An operating device which connects or disconnects the motor from the power supply. The term is used when the power poles are operated by an electromagnetic circuit, through the use of a coil and magnetic armature frame.
A switch that can repeatedly cycle, making and breaking an electrical circuit. When sufficient current flows through the A-coil built into the contactor, the resulting magnetic field causes the contacts to be pulled in or closed.
A heavy-duty industrial relay used to switch power to a power circuit
A larger version of the relay. It can be repaired or rebuilt and has moveable and stationary contacts.
A contactor is a device for opening and closing an electric power circuit.
A device for repeatedly opening and closing electrical circuits. Electrically, relays and circuit breakers also fulfill the same function.
In the condenser, the main switch that turns the condenser on.
A group or assembly of contacts-used with test sockets to describe the electrical interface between the device under test (DUT) and the test board. DUT Device Under Test
A contactor is an electrically operated switch usually used in control circuits and whose contacts are considered high amperage compared to a relay.
A mechanical or electromechanical device for making and breaking electrical continuity between two branches of a power circuit, thereby establishing or interrupting current flow.
1. An electrical switch, usually magnetically operated.
A style of relay used to control higher amounts of electrical current, typically greater than 10A. Generally used in electric circuits involving motors, lighting, and large inductive loads.
