Ohjausosassa

Ohjausosassa is a Finnish term used in technical and instructional texts to denote the part of a device, system, or enclosure where control functions are located. It is formed from the root ohjaus (control, guidance) and osa (part) with the inessive suffix -ssa, producing the sense “in the control part” or “in the control section.”

Usage and contexts

The phrase typically appears in user manuals, installation guides, schematics, and repair instructions. It refers to the physical area or compartment that houses control elements such as switches, indicators, controllers, and related circuitry. In many contexts, it helps distinguish the control portion from other sections of a machine or system, such as the power supply, processing core, or actuation section. For example, a manual might note that “ohjausosassa sijaitsevat pääkytkin ja ohjauspaneeli,” meaning that the main switch and control panel are located in the control area.

Relation to related terms

Ohjausosassa is closely related to ohjausosa (the control part) and to other terms describing interfaces or panels, such as ohjauspaneeli (control panel). The form ohjausosassa is the grammatical inessive case used when specifying location within something, and it is commonly replaced by other locational forms in different sentences (e.g., ohjausosassa on ...).
