Similarly circuit breakers are called Q because IEC 60750 says so. Where one or more sets of contacts is not used it is often not shown.

Practically a logic symbol means transistor diodes relays and other mechanical or optical details which provide function of closing or opening gates.
Symbol for relay coil. Core Coil That portion of the magnetic structure of a relay around which the coil is usually wound. Countries using American standards use IEEE Std 315-1975 ANSI Y322 Graphic symbols for electrical and electronic diagrams. Horizontal Symbol Vertical Symbol Description HCR21 VCR21 Relay Normally Open Contact HCR22 VCR22 Relay Normally Closed Contact HCR23R VCR23R Relay Form C HCR23 VCR23 Relay Form C Flipped HCR1 VCR1 Relay Coil HLR1 VLR1 Latch Relay Coil HLR2 VLR2 Latch relay child coil HCR1SSD VCR1SSD Solid State HCR1HSP VCR1HSP High Speed HCR1ACU VCR1ACU AC.
49 Zeilen Relay solenoid operated Coil and Switch Generic symbol Info. These terminal numbers are used to identify and separate the different component parts coil NC contacts etc included on the individual pieces of equipment. Here you can see the symbol of the latching relay.
ConceptDraw Electrical Engineering solution gives the opportunity to create a circuit diagrams both simple and difficult. Although this does not conform to the latest relay circuit symbol standards it may nevertheless be seen in some instances and it. Circuit symbol of a relay Note that on this symbol both normally open and normally closed contacts are shown.
Manufacturers of electrical relays timers counters etc include numbers on the terminal connection points. Relay symbol measurement relays Low power or sync relay It is used to open or close an auxiliary or secondary circuit depending on whether the intensity or power of the circuit being controlled remains in the range of a predetermined value and does not fall below that value they are known as synchrony relays since guarantee that there is synchrony to connect two sections of a circuit. Therefore the coil symbol is also shown for the reset coil in its reset state.
A number is often added to the letter to differentiate one device from another. Totally the logic circuits can involve millions of gates. The letters often represent the type of device such as M for motor starter or CR for control relay.
Relays symbols for use in electrical pneumatic and hydraulic schematic diagrams. Neither of those words start with K which sinks my theory. Crystal Can Relay A term used to identify a micro-miniature relay housed in a hermetically sealed enclosure that was originally used to enclose a frequency control type of quartz crystal.
Double coil latching relays are constructed with two magnetic coils. Coil is commonly symbolized as a circle with letters and number inside. Most of the latching relays are DPDT types and they used the latching principle for their operation.
Manufacturers terminal numbers are often. Unfortunately relay coil translates to relaisspule and contactor translates to schtz. Other circuits especially new that may be a bit older may show the relay coil as an actual coil.
Available in SVG PNG JPG DXF DWG formats. Also commonly used to. Single side stable type 1 coil latching type 2 coil latching type Non-polarized Polarized 4-terminal 3-terminal or or CONTACTS secondary or output.
