Most relay logic diagrams are in "ladder logic" form. Systems using relay logic diagrams in other forms include the , the many 20th century that controlled their by relays, and the designs for the various including the . Design tools for these include and .
The most common relays used to control electrical accessory devices in the automotive industry are Mini and Micro relays. 4 and 5 pin designs, SPST / SPDT are used in both styles of automotive relays. Normally open or normally closed types. Look for relay diagrams or a relay schematic that is printed on the side of the relay to determine it's function. 20, 30 and 40 amp relays are common in automotive use. Below are some examples of basic 12 volt car relays.
In many cases, it is possible to design a relay logic diagram directly from the narrative description of a control event sequence. In general, the following suggestions apply to designing a relay logic diagram:
Note:In a basic or resistor protection relay, pins 1 and 2 of the micro relays and pins 85 and 86 of the mini relays can be interchanged positive or negative. In a diode protected relay, Mini relays must be pin 85 (+) power, pin 86 (-) ground / Micro relays must be pin 2 (+) power, pin 1 (-) ground. Look for a relay diagram or a relay schematic that is printed on the side of the relay to determine.

4 prong relay diagram
hey does anyone have relay diagrams for 4 prongs? i'm going from a 4 prong to a five with a moomentary but dont know which slots are what, i looked and serched and could't find anything so i'm hopin you guys have somethin.
its a about half inch wide by an inch long with 2 prongs runnig paralel vertically and 2 running horizontally paralel
thanks again guys appreciate it
