- Switchman — A railway worker specialized in the manual operation or monitoring of track switches within a station or shunting yard, holding direct responsibility for directing trains and wagons onto the correct tracks. Figuratively, the popular Romanian idiom 'acarul Păun' describes an innocent or minor employee turned into a scapegoat to cover up the corruption, errors, or negligence of higher-ups or an entire system.
- Switchmen — The plural form of the masculine noun acar; it designates multiple railway switchmen responsible for operating track switches within a railway station. Secondarily and colloquially (originating from an occasional literal mistranslation of scientific jargon), the term is sometimes conflated with mites and ticks belonging to the subclass Acari (acarieni).
- Manageable — Capable of being administered, managed, governed, or controlled without major difficulties; suitable for an efficient organizational structure. In computer science and networking, it refers to equipment (such as a switch) or a software platform that allows configuration, monitoring, and operational parameter control by an administrator.
- To engage — To establish an electrical connection by closing a circuit using a switch, relay, contactor, or circuit breaker; to put an automated system or apparatus into operation. Broadly, the action describes the automatic or manual triggering of a switching mechanism, being the opposite of the term 'to trip' or 'to uncouple'.
- Engagement — The act of engaging or closing an electrical circuit; the technical operation of making a circuit or coupling a mechanism via a switching apparatus. In power systems, the process represents the restoration of current flow within a network, which can be performed manually by an operator or automatically by specialized relays following the restoration of nominal parameters.
- Switchgear — A complex assembly consisting of several structurally interconnected technical devices, instruments, and accessories, used for the control, switching, protection, or distribution of electrical energy or for executing a specific industrial operation. In common language, the term can describe the totality of equipment necessary for the operation of a laboratory or a high-power facility.
- Switchgear — An obsolete or neologic technical variant (borrowed from French) for 'aparataj'; an assembly consisting of electrical apparatuses, switches, relays, and switching devices used for equipping electrical panels and managing power distribution networks.
- Autoselector — An electromagnetic or electronic device or switch used in automation systems and telecommunication networks to automatically select a free line, a transmission channel, or a specific circuit without manual intervention. This structural mechanism ensures the rapid and efficient routing of signals or calls to the correct destination based on pre-programmed criteria.
- Azobenzene — A crystalline, orange-yellow organic chemical compound with the molecular formula C12H10N2, consisting of two benzene rings linked by an azo group (-N=N-); it is the simplest azoromatic compound and serves as a core substance in the manufacturing of azo dyes and in the study of photoisomerization.
