1. Identify the electrical action
Switch action describes the relationship between actuation and the resulting electrical state over time. E-Switch's momentary definition concerns a circuit that remains changed while force is applied and returns to its normal position when that force is removed. The release of force is therefore central to the description. An inventory label saying pushbutton omits this behavior, even if it identifies a recognizable actuator on the outside of the component.
For an identified momentary product, retain both parts of the manufacturer's description: the state during applied actuation and the return after release. The action field should communicate that relationship without becoming a contact map. It does not identify a particular physical terminal or provide a measurement of a seller's switch. The technical classification remains useful because it says what kind of actuation behavior the documented product is intended to provide, before the electrical circuit arrangement is considered separately.
2. Read a maintained-action example
E-Switch's alternate-action entry describes a pushbutton-style product in which the changed electrical state is maintained between actuations. This supplies a concrete maintained-action example. Unlike the momentary definition, removal of the first applied force is not itself the description of a return to the previous normal state. Preserve the retained-state meaning rather than replacing it with a vague statement that the switch stays pressed or looks mechanically latched.
The example needs its product context. It does not establish that every maintained switch uses an alternate-action pushbutton mechanism, or that every pushbutton exterior has maintained action. A seller comparing two identified switch references should look for the documented action applicable to each. Similar actuator shape leaves that question open. Conversely, a different exterior does not change the definition of state retention. The meaningful comparison concerns the electrical action described by the manufacturer, not an attempt to reconstruct every mechanical design.
3. Keep normal contact condition separate
Normally open and normally closed describe the circuit in its normal switch position. E-Switch gives these definitions separately from momentary and alternate action. That separation matters because a normal-state label does not answer what happens after actuation or after the applied force is removed. A short entry containing only normally open can therefore be incomplete about action even while correctly stating the normal electrical condition of the product.
Retain the normal-condition field beside the action field instead of using either as a substitute. One question asks which electrical state belongs to the documented normal position; the other asks how the changed state relates to actuation and release. A reviewer can understand that distinction without a terminal assignment or an assumed contact circuit. It also avoids importing relay coil and contact-rating terminology as the answer to a different electromechanical-switch behavior question. Ratings and actuation behavior each need their own applicable evidence.
For example, two identified product descriptions could retain the same normal-contact wording while documenting different behavior after force is removed. The common normal-state term would then leave the central action difference hidden. Preserving the temporal condition makes the comparison clearer: momentary action refers to return after release, while the alternate-action example refers to state retained between actuations. These are descriptions of the documented product behavior. They do not instruct the recipient to infer the action from a cap position or replace the exact switch reference with an equipment operator's description.
4. Separate action capability from observed condition
Exterior observations describe the actual item but do not replace its documented action. A cap shape, tactile impression or former panel legend can help connect records to hardware, yet none independently supplies the electrical state after release. A panel label may describe an equipment function rather than the internal action of the loose component. Preserve that context without turning the label into a functional test or a complete manufacturer product description.
For an ICULTRA switch enquiry, retain the exact product reference with its momentary or maintained action and separate normal-condition wording. Keep an existing functional report distinct, identifying which material it actually covers. The additional decision here is the actuation-to-state relationship; general quantity and packing fields can remain in the wider stock list. No electrical rating, operating-force, bounce or life value follows from the glossary definitions, and no present switching result or application acceptance is established by this classification.

E-Switch's momentary, alternate-action and normal-contact definitions support these distinctions. The maintained example remains pushbutton-specific; no terminal map, force/bounce/life value or actual switching test is supplied.
