Product Name: E-TEN1121 3-Pin Toggle Switch

Appearance and Structural Features:
Overall Structure: This is a compact metal frame toggle switch. The main body features a rectangular insulating housing, typically in black or dark red, with a sturdy metal bracket on the outside. The top is equipped with a threaded bushing, a metal toggle lever, and a fixing nut.

Materials and Manufacturing:
Housing: Made of high-temperature resistant insulating plastic, paired with a nickel-plated metal frame, ensuring both electrical insulation safety and enhanced mechanical strength.
Toggle Lever: Solid metal cylindrical lever with a clear operating feel and high durability.

Functional Design (Key Features):
3-Pin Terminal Block: Three terminal pins are located at the bottom (marked as hole-punched solder pads on the drawing). This 3-pin design typically corresponds to a Single-Pole Double-Throw (SPDT) circuit structure, meaning it has one common terminal and two selector terminals, allowing for "on-off-on" or circuit switching functionality.
Mounting Method: Uses standard M12x0.75 threaded bushing mounting, along with the included nut and washer, for secure installation on equipment panels.
Status Indicator: A red and white "ON" label is attached to the panel, clearly indicating the switch's on/off position. The model and parameters are printed on the side.
Dimension Specifications (Based on Drawing Markings):
Total Height: Approximately 45.5mm (including lever: lever height 17.5mm + bushing height 9.5mm + body height 19mm).
Body Dimensions: Length 29mm × Width 15.8mm × Height 19mm.
Mounting Hole Diameter: Standard 12mm (thread specification M12x0.75).
Terminal Spacing: Compact terminal arrangement at the bottom, with a spacing of approximately 6.3mm (center-to-center).
Electrical Characteristics:
Rated Current/Voltage: 15A / 250V AC. This indicates it is a high-current rated switch, capable of handling high loads and suitable for high-power electrical equipment.
Circuit Logic: Based on the 3-pin layout, the standard logic is typically ON-OFF-ON (off in the middle, on on both sides) or ON-ON (double-throw switching), depending on the internal contact design.
