A strat 5 way switch wiring diagram represents electrical connections for specified positions of a selector. It can show which contacts are connected in each position, but it does not establish a universal arrangement of physical terminals. The printed drawing, the selector’s visible layout, and the actual terminal map are not automatically interchangeable.
To interpret a diagram, read each selector position separately and trace the connections shown for that state. Use the diagram’s labels and symbols, and treat wire colors or terminal locations as meaningful only when the applicable documentation identifies them. This method helps explain what the drawing says without assuming a particular switch model, pickup arrangement, or wiring procedure.
What strat 5 way switch wiring diagrams show
A wiring diagram is a representation of electrical connections under stated conditions. For a selector, those conditions include its positions: the diagram may show a different set of connected contacts for each position. Read the symbols and labels as the source defines them, and keep the drawn electrical relationships distinct from the component’s physical appearance.
A selector position describes a switching state, not a terminal’s location. A drawing may arrange symbols in a convenient way to make the circuit understandable. That layout alone does not prove that a real switch has terminals in the same order, orientation, or grouping. Nor does the fact that a diagram shows a connection in one position establish that the same connection exists in another position. Each state needs to be read on its own terms.
This distinction matters when a diagram is being used to identify connections. A reader can determine what the drawing depicts by following its lines and symbols, but cannot safely transfer that interpretation to an unidentified component based only on where its terminals appear. Terminal identification depends on documentation for the exact switch and equipment, including the connection diagram, terminal markings, circuit function, and permissible load. A generic physical-layout inference is not a substitute for that information.
The name of a selector or the number of positions does not, by itself, establish a universal terminal map. The available information here does not define a specific switch’s pole arrangement, terminal numbering, contact sequence, or pickup combinations. Avoid adding those details unless the applicable diagram or verified documentation supplies them. A general explanation should stay at the level of reading depicted states rather than presenting an unverified wiring map.
How to read strat 5 way switch wiring by selector state
Start with the diagram’s own position labels and symbols. Identify one selector position, then trace each represented connection through the drawing. Record only the contacts that the diagram shows as connected in that state. Repeat the process separately for every other position shown. This state-by-state approach makes it less likely that a connection from one position will be mistakenly attributed to all positions.
Follow the diagram’s notation rather than relying on a visual guess. Lines, contact symbols, labels, and any accompanying key should be interpreted according to the documentation that accompanies the drawing. If a line or symbol is ambiguous, the diagram alone may not resolve its meaning; do not fill the gap by assuming that a nearby terminal is the intended one. The physical placement of a symbol on a page can help present the circuit, but it is not proof of a real terminal’s location.
Keep diagram interpretation separate from component identification. A diagram may communicate that a connection is made in a given selector state while leaving the actual terminal numbering or orientation to a separate drawing or marking. In that case, use the relevant terminal information for the actual switch rather than mapping the drawn symbols onto the switch by eye. The terminal marking and documented connection diagram need to agree with the circuit function and permissible load for the exact switch and equipment.
Do not assign meaning to wire color unless the applicable documentation does so. A color may help distinguish wires within a particular documented circuit, but it cannot establish a general terminal function across unspecified installations. Likewise, do not infer a particular pickup combination merely from the selector’s position number. The diagram must show that circuit relationship, and its labels must be applicable to the equipment being considered.
A useful written reading of a diagram is therefore limited and explicit: for each labeled selector position, state which contacts the drawing represents as connected, using the drawing’s own identifiers. Keep any unresolved terminal identity unresolved. This describes the evidence visible in the diagram without claiming that every selector with a similar appearance has the same internal switching behavior.
How to verify a selector’s terminal map
Interpreting a diagram and identifying an unknown selector are different tasks. The diagram explains the connections it represents; it does not necessarily identify an unmarked component in front of the reader. For that component, consult its applicable documentation and markings. The information needed includes the connection diagram, terminal identification, circuit function, and permissible load for the exact switch and equipment. If those details are absent or uncertain, the terminal map remains unresolved.
Do not treat a terminal’s position in a drawing or on the component as sufficient identification. Also do not transfer a map from an unrelated diagram based on visual similarity. No universal terminal-position map, wire-color convention, or specific contact sequence is established here. A continuity-check procedure is not provided because no applicable verification method or test conditions are established by the available information.
For work involving wiring, use the applicable deenergization and qualification requirements. The general guidance here is about interpreting documented switching states, not performing a live-circuit test or providing installation steps. If the relevant documentation does not identify the terminals or explain how the diagram applies to the actual equipment, do not guess at the missing connections.

What this guide does not establish
This guide does not determine terminal positions, terminal numbers, wire colors, pickup combinations, contact sequence, or compatibility for a particular selector or installation. It also does not establish a model-specific wiring procedure. Those details require applicable documentation or verified information for the exact switch and equipment. A drawing that resembles a known layout is not enough to establish that identity or its connections.
The practical boundary is straightforward: use the diagram to understand the states it depicts, and use exact, applicable documentation to identify the real terminals and permissible circuit. If a specific installation question cannot be answered from that documentation, seek qualified assistance rather than relying on a generic map.
In short, strat 5 way switch wiring diagrams should be read position by position, tracing only the connections they explicitly show. Keep the selector’s electrical states separate from physical terminal locations, and do not assume wire colors or a pickup combination without applicable documentation.
