Product Name: KCD4 Series Double-Pole Double-Throw Switch (DPST, with Light, 6 Pins)

Appearance and Structural Features:

Overall Structure: This is a black square double-pole rocker switch. It consists of two independent switch units side by side, mounted on a common black plastic base. The switch panel has two red transparent rocker arms with clear white “I” (on) and “O” (off) markings.

Materials and Manufacturing:

• Shell: Made of black high-temperature resistant engineering plastic (usually nylon PA66), providing good insulation and flame retardancy.
• Contacts: There are 6 metal terminal pins at the bottom (plug-in type), arranged in two rows. This design allows for flexible wiring configurations (e.g., series, parallel, or independent control).
• Indicator Light: A neon bulb or LED indicator light is built into the red transparent rocker arm. When the switch is in the “ON” position, the red light will illuminate, providing an intuitive status indication.

Functional Design (Key Features):

• Dual-Pole Double-Throw/Dual-Pole Single-Throw (DPST): This is a two-way switch that can control the on/off of two circuits simultaneously. The 6-pin design typically means it supports more complex circuit connections (e.g., simultaneously cutting off live and neutral wires).
• High Load Capacity: According to the silk screen and instructions on the picture, the switch has a rated current of up to 16A (some markings even support 20A/15A switching), and a rated voltage of 250V AC. This allows it to handle the starting current and operating load of high-power appliances.
• Long Lifespan: The picture specifically states “10,000 TIMES ON/OFF ELECTRICAL LIFE”, indicating that its electrical lifespan is at least 10,000 operations, making it highly durable.

Dimension Specifications (Based on Drawing Markings):

• Panel Size: Approximately 31mm x 25mm (1.22in x 0.98in).
• Mounting Hole Spacing: Requires use with corresponding rectangular cutouts.
• Overall Height: Approximately 31mm - 40mm (depending on pin length and measurement point).

Electrical Characteristics:

• Rated Voltage: 250V AC / 125V AC.
• Rated Current: 16A (Picture description mentions 16A, silk screen shows 15A/20A. Typically, KCD4 switches are rated 15A-16A at 250V and 20A at 125V).
• Operating Temperature: -25°C to 85°C.
