Rotary switch EB948275234 SPDT, 3 A, 220 VAC

Rotary switch EB948275234 is a single-pole double-throw (SPDT) manual selector designed for low-power AC switching. Rated for 3 A at 220 VAC, the compact mechanical switch provides stable contact selection between two circuits or positions. It is intended for straightforward on/off or position selection tasks where a durable, easy-to-operate rotary control is required.

Advantages

The switch offers a compact footprint with a simple rotary mechanism that enables positive tactile feedback and clear position selection. Its 3 A, 220 VAC rating matches common low-power AC control requirements, and the SPDT contact arrangement allows selection between two circuits without complex wiring. The mechanical design minimizes electronic complexity and is suitable for devices where straightforward manual switching reliability is preferred.

Suitable for

• Control panels and operator interfaces requiring manual circuit selection
• Household and small appliance position or mode switching
• Low-power AC signal routing and simple on/off functions
• Prototyping and repair of equipment with SPDT rotary switch requirements

Key specifications

• Contact configuration: single-pole double-throw (SPDT)
• Rated current: 3 A
• Rated voltage: 220 VAC
• Switch type: manual rotary selector
• Operation: mechanical with defined stop positions
• Typical application: low-power AC switching and position selection

How to use

Mount the rotary switch in the panel cutout designed for its dimensions and secure it with the appropriate nut or mounting hardware. Wire the common terminal to the input circuit and the two throw terminals to the circuits or loads to be selected, observing proper insulation and wiring practices for 220 VAC. Rotate the knob to change the connection between the common and one of the throw terminals; verify correct contact by measuring continuity or by observing the connected circuit operation. Ensure all power is disconnected before installation or maintenance.

Usage recommendations

Use the rotary switch within its rated limits of 3 A and 220 VAC. Avoid switching inductive loads near the rating without additional contact protection (such as snubbers or relays) to prevent contact wear. For long-term reliability, mount the switch in a location protected from excessive vibration, moisture, and conductive dust, and perform periodic inspections if used in frequent-switching applications.
