In the world of industrial controls and electrical switching, reliability is paramount. When standard pushbutton switches don't meet your needs and you need a robust solution to select between multiple circuit states, a Metal Selector Switch becomes an indispensable component. YIJIA, a leader in industrial switch manufacturing with over two decades of experience, has designed a line of metal selector switches that set the standard for durability, performance, and safety.
Unlike simple pushbutton switches that provide a single, momentary action, selector switches allow the operator to rotate a knob or lever to one of several predetermined positions. Each position corresponds to a different electrical command, enabling control of a variety of machine functions—from switching between automatic and manual modes, controlling speed, to selecting different power sources.
YIJIA's Metal Selector Switch housing and actuator (button head) are meticulously crafted from high-grade stainless steel and metal. This metal construction offers superior resistance to impact, corrosion, and harsh environmental conditions, significantly outperforming plastic-cased switches. This inherent ruggedness minimizes unplanned downtime and reduces long-term maintenance costs, resulting in an excellent return on investment.
YIJIA has carefully optimized the internal contact structure of its Metal Selector Switches. These switches utilize an improved spring mechanism and high-quality silver alloy contacts to withstand high inrush and steady-state currents. Silver alloy contacts offer low resistance and high resistance to welding and corrosion, which are critical for maintaining a stable connection over thousands of operating cycles.
In addition, internal insulation and supporting components are constructed from high-performance engineering plastics. These materials offer excellent wear resistance, high impact strength, and aging resistance, remaining stable even in environments exposed to oils, chemicals, and temperature fluctuations. The combination of a rugged metal shell and high-performance core ensures long service life in even the most demanding applications.
Contact Configuration: Various contact configurations are available, including 2-position and 3-position.
Contact Material: Silver alloy (cadmium-free) ensures high conductivity and arc resistance.
Electrical Ratings: Typically 10A-16A at 250VAC/380VAC; 5A-10A at 24-240VAC/VDC. Higher current ratings available upon request.
Insulation resistance: >100 MΩ (at 500 VDC).
Dielectric strength: 2000 VAC, 50/60 Hz, for 1 minute between live parts and ground.
Mechanical life: Over 1,000,000 cycles.
Electrical life: Over 100,000 cycles (at rated resistive load).
Casing material: Stainless steel, brass, or aluminum alloy.
Operating temperature range: -25°C to +85°C.
Protection rating (IP rating): IP65 (oil and dust proof) is standard when properly panel mounted. IP67 and other ratings are available.
Termination type: Screw terminals, solder lug terminals, or PCB pins.
Actuator types: Knob, key, lever, and flush-mount for safety applications.
| Application Scenario | Industry | Function |
| Manual/Auto Mode Selection | Industrial Automation, Manufacturing | Allows operators to switch a machine between automatic (cycle) mode and manual (jog/setup) mode. |
| Motor Control (Forward/Stop/Reverse) | Material Handling, Conveyor Systems, Machine Tools | Provides direct control for a three-phase motor's direction of rotation (e.g., for a hoist or a conveyor). |
| Power Source Selection (Main/Generator) | Electrical Panels, Backup Power Systems, Marine | Switches the electrical load between the main power grid and an auxiliary generator source. |
| Control Voltage Selection | HVAC Systems, Test & Measurement Equipment | Selects between different control voltages (e.g., 24V, 110V, 220V) for system configuration or testing. |
| Function Selection (Speed/Torque) | Power Tools, Industrial Drives, Agricultural Machinery | Enables the operator to select different operational modes, such as high/low speed or high/low torque. |
| System Isolation / Bypass | Water Treatment, Process Control, Petrochemical | Used to isolate a part of a system (e.g., a pump or sensor) for maintenance or to bypass it during operation. |
| Operator Interface for Multi-State Processes | Packaging Machinery, Printing Presses, Food Processing | Selects between different pre-set programs or process parameters (e.g., Package Size A, B, or C). |
