Types
This is an early invention used to start and stop electric motors, named after a kitchen utensil.
Knife Switch
This shows whether an overload has taken place within a device.
Trip Indicator
This type of current requires more effort to break electrically then its counterpart
DC
This occurs when strands of wires are crossed across the inputs or outputs of a 3 phase contactor.
A flash will turn your stache to ash
This happens when a relay “sets” itself by using a NO switch to keep the the coil energized.
Latch
This is a device that uses push buttons to open or close electrical connections.
Manual Contactor
This is a device that changes its resistance value when heat is applied or taken away.
Thermistor
This increases when the contacts of a relay or contactor corrode or rust.
Resistance
This occurs when too much current is passed through a relay or contactor
The burning is quite concerning
This has replaced relay based logic. These devices control every day machines and are what Grob Machines are based on.
PLC
This is a device that makes or breaks a connection using electricity.
Magnetic Relay/Contactor
These are metallic objects that conduct electricity, used to break/make electrical circuits.
Contacts
This is a property of an electric conductor or circuit that causes an electromotive force to be generated by a change in the current flowing.
Inductance
This happens when a relay or contactor is opened or closed too slowly.
You'll put the spark in an arc
This metal that is used in automatically resetting relays, difference in expansion rates allows this metal to bend.
Bimettalic Strip
This is a Manual contactor that has an overload protection device.
Manual Motor Starter
This is a device that opens when too much current passes through it.
Overload
The input side of a 3 phase contactor is signified by this letter followed by a 1,2, or 3
L
This occurs when the voltage is too high when powering a relay.
Your coil will soil.
This was the first use of electro-mechanical relays.
Telegraph
This is a type of relay that contains no moving parts and are more efficient and reliable than traditional relays.
Solid State Relay
This is a wrapped wire that creates a magnetic field when current passes through it.
Coil
Different levels of this measure of electrical pressure can be used in relays and contactors. One level to close the contacts and another to be transferred/conducted.
Voltage
This occurs when the A1 of a relay or contactor is not connected to the control voltage.
Nada whole ladda
The neutral side of a relay coil is called this in electrical prints.
