3-Pin Screw Terminals Toggle Switch 12mm Mounting Rocker Switch with 15A 250V AC Overload Protection

Product Name: E-TEN1122 3-Pin Screw Terminal Toggle Switch

Appearance and Structural Features:

• Overall Structure: This is a compact metal frame toggle switch. The main body features a rectangular insulating housing (commonly orange or black), surrounded by a sturdy metal bracket. 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 (such as bakelite or nylon), paired with a galvanized or 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 Screw Terminals: There are 3 terminal blocks at the bottom, each with screw holes and wire-pressing clips (Screw Feet). This design allows users to directly secure wires with screws without welding, greatly facilitating on-site installation and later maintenance and replacement.
• Circuit Logic: 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. According to the "ON-OFF-ON" markings on the picture, it supports the function of being off in the middle and on on both sides, or can be used for circuit switching.
• Mounting Method: Uses standard M12x0.75 threaded bushing mounting, along with the included nut and washer, for secure installation on equipment panels.
• Status Indication: 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 toggle 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: The terminals at the bottom are closely arranged, with a spacing of approximately 6.3mm (center-to-center).

Electrical Characteristics:

• Rated Current/Voltage: 15A / 250V AC. This indicates that it is a high-current switch capable of handling high loads, suitable for power-consuming electrical equipment.
