How To Read Circuit Diagrams Part II A type of rotary switch symbol frequently used in circuits of commercial equipment is a sort of picture diagram, illustrated by the example below. In switches of this construction the switch ' 'arm" is a metal ring, or segment of a ring, on the wafer. It makes continuous contact with a fixed spring contact, indicated by the longer arrows in the example. The ring has one 38 or more projections ... Navy Electricity and Electronics Training Series (NEETS ... The schematic symbol has two points at which current can enter the switch, so this is a double pole switch. Each of the poles is mechanically connected (still electrically separate) to one point, so this is a single throw switch. Only one throw is required to route two separate circuit paths through the switch. Schematic symbols of switches tpub The schematic symbol shown in figure 3 5(A) shows that this switch breaks the circuit in two places (at both terminals). The upper part of the schematic symbol indicates that these contacts are in the open position and the circuit will close when the switch is acted upon (manually or automatically). The lower symbol shows closed contacts. These contacts will open the circuit when the switch is acted upon. Rotary wafer switch Schematic question | QRZ Forums In tracing wires down in the radio to match up with what I'm seeing on the schematic, some go to the Rotary (wafer) switches of course. However, I don't see any numbering on the switch so I can't seem to figure out what wire is which pin when comparing the two. Antique Radio Switch Schematic Symbol imoneypage Antique radio switch schematic symbol Locate parts figure out the schematic assemble light fuse and step away rich gave me a copy of the angela instruments catalog the size of a small town phone book. Figure 3 9.Wafer switch tpub Figure 3 9.—Wafer switch. Figure 3 9(B) is an illustration of the entire switch and its schematic symbol. Since the switch has two wafers mechanically connected by the shaft of the switch, the shaft rotates the movable portion of both wafers at the same time. Symbol of Switches, Push buttons, Circuit Switches... Symbol of Switches, Push buttons, Circuit Switches... The switches, pushbuttons, circuit switches... are electrical, electronic or mechanical designed to interrupt or divert the flow of electric current or other signals in an electrical circuit devices. Navy Electricity and Electronics Training Series earth2.net Since the switch has two wafers mechanically connected by the shaft of the switch, the shaft rotates the movable portion of both wafers at the same time. This is represented on the schematic symbol by the dotted line connecting the two wafers. Electrical CAD Symbols Category: Selector Switches symbols. Electrical Symbol Category: Selector Switches.

Schematic symbols are used to represent different electronic components and devices in circuit diagrams from wires to batteries and passive components to semiconductors, logic circuits and highly complicated integrated circuits. Reading Heathkit Switch Diagrams antiqueradios Unfortunately, schematics were not drawn such that understanding switch contacts is easy or sometimes even possible. But, first start with the notes on the side of the schematic diagram that tells you in which position the switch is drawn.
