svitsjer

Svitsjer is the Norwegian term for switches, devices used to connect or disconnect an electrical circuit and thereby control the flow of electricity or select between different circuits or settings. They are a fundamental part of electrical installations and can be operated manually or automatically.

Common types of svitsjer include mechanical switches such as toggle switches (a lever that moves between on and off), rocker switches (a rocking actuator), push-button switches (actuated by pressing), slide switches (a sliding actuator), and rotary switches (a rotating knob selecting a circuit). Electronic switches, including solid-state switches and relays, perform switching without mechanical movement and are used to control higher power with low-power control signals. Switches are rated by voltage, current, and breaking capacity, and may feature latching, momentary actuation, or illumination.

Applications of svitsjer span residential and industrial settings. In homes, they control lighting, outlets, and appliances. In industry, they manage motors, heaters, and control circuits. The suitability of a switch depends on its electrical rating and its enclosure protection (IP rating), which determines where it can be safely installed (indoors, outdoors, damp environments, etc.).

Safety and standards: Electrical installations using svitsjer must meet national and international standards. In Norway, this typically involves compliance with NEK 400 and related regulations, proper isolation procedures, clear labeling, and appropriate grounding. Proper selection, installation, and maintenance of switches help prevent electric shock, short circuits, and fire hazards.
