Switches
Operator, safety, ignition, and position switches.
Describe what the switch commands or confirms and whether it is operated by the operator, pressure, position, temperature, or a mechanical linkage. Compare connector and pin arrangement, thread or mounting shape, actuator style, number of positions, labels, circuit context, and installed orientation without inferring function from the housing alone.
Use the machine identity, installed function, measurable interfaces, readable markings, and source photos together. A matching shape, connector, or single dimension is not proof of fitment.
Identification starting points
Three evidence paths to use together
Machine and function
Record the complete machine identity, installed system, exact position, and job performed by the component.
Interfaces and dimensions
Measure the physical features that connect, mount, seal, rotate, guide, or retain this electrical-part.
Identifiers and source evidence
Capture labels, part and casting numbers, revisions, full views, close-ups, and the surrounding assembly.
Selection checklist
Details to compare before requesting a match
- Machine identityBrand, full model, serial or PIN, electrical option, and installed configuration.
- Function and locationWhat the component controls or monitors and its exact machine position.
- Electrical interfaceVoltage, connector shape, pin count, terminal layout, and wire orientation.
- Mounting detailsBracket, thread, sensing end, housing, fasteners, and installed clearances.
- Label and revisionPart number, manufacturer label, calibration, software or hardware revision when shown.
- Circuit evidenceHarness context, mating connector, wire length, full photos, and readable markings.
Frequently asked questions
Switches identification
Can switches be confirmed from appearance alone?
No. Similar-looking candidates can differ in dimensions, interfaces, internal configuration, material, or application. Use appearance only as a starting clue and compare machine identity, function and location, electrical interface, mounting details together with readable identifiers.
What if the original part number cannot be read?
Provide the machine brand, full model, serial or PIN, exact installed position, overall photos, close-ups of every marking, and the measurable electrical-part interfaces. Missing identification data should remain unverified rather than being guessed.
Why does the installed position matter?
Switches can change by machine side, function, parent assembly, serial range, or option package. The installed location helps distinguish candidates that otherwise share a similar shape or connector.
Does a catalog candidate mean the part fits?
No. A result only places the item within the Switches review path. Fitment remains unverified until the machine record, identifiers, dimensions, interfaces, and installed configuration have been reviewed together.
What photos help identify switches?
Include the installed context, a full view of the component, every side and mating interface, readable labels or castings, and close-ups of critical measurements. Keep the parent assembly or mating component visible where practical.
Still not sure which part you have?
