2P Electrical Selector Switch

The 2P Electrical Selector Switches are mainly used in electrical circuits with AC 50/60Hz, rated voltage 110/690V, DC voltage up to 220V and rated current up to 160A. The products are widely used and can replace various national switches as circuit control switches, measuring equipment switches, motor control switches and main control switches, welding machine switches and so on.

What Is a 2P Electrical Selector Switch?

A 2P Electrical Selector Switch is a manual rotary control device used to open, close, and switch between different electrical circuits. Designed for AC 50/60Hz systems with voltages up to 690V, it allows operators to select multiple functional paths—such as switching motor speeds or toggling between manual and automatic CNC control modes—using a single, centralized interface.

The main functions of the universal transfer switch include:

(1) Switching function: 2P Electrical Selector Switch can realize the opening and closing, switching and conversion of the circuit to meet the control needs under different working conditions.

(2) Control function: it can realize the control of motor, transformer, contactor and other electrical equipment to realize automatic control.

(3) Protection function: 2P Electrical Selector Switch can realize the protection of short circuit, overload, overheat and other abnormal conditions of the circuit to ensure the safe operation of electrical equipment.

Key Advantages and Technical Excellence

Reliable Control & Efficiency

• Wide Current Range: Available in rated currents of 16A, 32A, 50A, 75A, 100A, and up to 160A to suit various load requirements.
• Color-Coded Durability: We utilize blue and white color differentiation to distinguish between high and low voltage/current applications, which prolongs product life and prevents operational errors.
• Multi-Functional Replacement: This switch can effectively replace various national standard switches for circuit control, measuring equipment, and welding machines.

Improved Safety & Operation

Safety is integrated into the core of our 2P Electrical Selector Switch design. It provides comprehensive protection against common electrical hazards:

• Integrated Protection: Features built-in mechanisms for overload protection and short circuit protection.
• Synchronous Control: Realizes the control of motors, transformers, and contactors to achieve seamless automatic or manual control.
• Thermal Management: Engineered to operate in extreme ambient temperatures ranging from -25℃ up to +65℃, ensuring stability in harsh industrial environments.

Space-Saving and Durable

By consolidating multiple control functions into one unit, the 2P Electrical Selector Switch saves valuable space on CNC control panels and distribution boards. Its robust construction ensures reliable performance at altitudes up to 2000m and maintains high insulation integrity even in environments with up to 90% relative humidity (at 20℃).

Normal working conditions

1. Ambient air temperature does not exceed +65℃, and the average temperature within 24 hours does not exceed +35℃.

2. The overall surrounding air temperature is not lower than -25℃.

3. The altitude of the installation site does not exceed 2000m above sea level.

4. If the relative humidity of the air, the maximum temperature of +40 ℃ does not exceed 50%, at lower temperatures allow a higher relative humidity, such as 20 ℃ can reach 90%. Special measures should be taken for occasional condensation due to temperature changes.
