Rotary switch Merten MEG3115-0000 1P metallic, 250 V AC, 10 A

Merten MEG3115-0000 is a 1-pole rotary switch with a metallic finish designed for manual control and switching of AC circuits. The switch is rated for 250 V AC and a nominal current of 10 A, offering a compact and robust solution for single-pole installations in electrical panels, wall boxes or control boxes. Its metal appearance and straightforward rotary operation make it suitable where a durable selector with clear tactile feedback is required.

Advantages

The rotary mechanism delivers reliable, repeatable switching action and clear position feedback to the operator. The compact single-pole construction allows installation in confined spaces while maintaining access to a 10 A switching capacity at 250 V AC. A metallic finish provides enhanced surface durability and a professional appearance compatible with a variety of interior and equipment styles. The design focuses on ease of installation and straightforward mechanical operation without electronic complexity.

Suitable for

• Manual control of lighting circuits in residential and commercial settings
• Switching small motors and fans within the rated current
• Selector switch functions in control cabinets and distribution panels
• Replacement or upgrade of single-pole wall-mounted selectors

Key specifications

• Poles: single-pole (1P)
• Rated voltage: 250 V AC
• Nominal switching current: 10 A
• Actuation type: rotary selector
• Finish: metallic appearance
• Mounting: designed for panel or wall-box installation
• Suitable loads: lighting, small motors, control circuits within rated limits

How to use

Install the rotary switch into the intended panel or wall box following local electrical regulations and switch off power before beginning work. Connect incoming and outgoing conductors to the switch terminals according to the wiring diagram that applies to your installation and tighten terminal screws to the recommended torque. After mounting and wiring, restore power and verify correct operation by rotating the selector through its positions to confirm reliable contact and intended switching behavior.

Recommendations

Use the switch only within its rated voltage and current limits. For circuits supplying inductive loads such as motors, confirm that inrush currents do not exceed the device’s switching capability. If the application requires frequent switching or is subject to high inrush currents, consider using an appropriately rated contactor or motor starter. Ensure periodic inspection for secure connections and normal mechanical operation.
