The YESWITCH HT802 series is a high-performance, high-current, two-position (dual-way) toggle switch designed for harsh industrial environments. Its core design concept is to achieve extremely high electrical load capacity, mechanical life, and environmental tolerance within a compact package, meeting the high reliability requirements of critical control components in equipment such as heavy machinery and aerial work platforms.
Unique Dual-On/Off Function
Functional Description: This switch features a double-pole, single-throw (DPST) structure, providing two independent circuit paths. A single toggle of the handle simultaneously connects or disconnects two completely isolated circuits.
Application Advantages:
Synchronous Control: It can simultaneously control the main power and signal circuits of a device, such as connecting the power supply to a motor and the signal supply to a controller, ensuring synchronized and safe operation.
Circuit Isolation: The two circuits are independent of each other, preventing interference between high- and low-voltage circuits or circuits with different signal types, thereby improving system stability and safety.
Redundancy: In some applications, it can serve as a simple redundancy backup to enhance system reliability.
Sturdy and Durable Flat Metal Handle
Material and Craftsmanship: The handle is made of high-strength metal (such as copper alloy) for exceptional mechanical strength and impact resistance.
Flat Design Operation: Compared to round handles, the flat design is less susceptible to accidental triggering, providing enhanced safety.
Operational Feel: The lever provides a crisp, firm feel, making it easy to operate even with gloves, ergonomically designed for optimal operation.
Space Saving: The flat design occupies less vertical space on the device panel, facilitating a compact layout.
High-Reliability PC Terminals:
Provide a secure wire connection, firmly clamping the wire to prevent loosening, disconnection, or poor contact caused by equipment vibration, significantly improving connection stability and security.
High-Current Carrying Capacity: The terminal design is optimized for high currents, with a large contact area and low resistance, effectively reducing heat generation and ensuring stable current transmission of up to 16A.
High IP68 protection rating
Full protection: Completely prevents foreign objects and dust from entering, preventing even the finest dust particles from entering the switch interior. Suitable for dusty environments such as construction sites and mines.
Even when working on aerial work platforms in rainy weather or when equipment requires thorough cleaning, the switch interior remains dry and operational.
Sealed design: Precision O-ring seals, multi-layer interface seals, and a sealing compound potting process ensure complete isolation of the switch's internal structure from the external environment.
16A High Current Carrying Capacity
Powerful Load Capacity: With a rated current of up to 16A (250VAC or 28VDC), it can directly control high-current loads such as medium-sized motors, high-power lighting, and hydraulic solenoid valves. This eliminates the need for intermediate relays, simplifying circuit design, reducing system costs, and reducing points of failure.
Low Contact Resistance: Excellent electrical conductivity, strong arc suppression, and low contact resistance minimize power loss and heat generation within the switch.
Long Electrical Life: Guaranteed to operate for tens of thousands of times even under high loads, ensuring durability.
Excellent Mechanical and Environmental Adaptability
Long Mechanical Life: Its robust internal structure and high-wear-resistant materials ensure a mechanical lifespan of typically 100,000 cycles or more.
Wide Temperature Range: It operates stably in extreme ambient temperatures ranging from -40 to +85 degrees, adapting to a wide range of climates, from the bitter cold of northern China to the scorching heat of southern China.
Vibration and Shock Resistance: Specifically designed for the high-vibration environments of heavy machinery, its shock-resistant internal structure prevents position shifts or internal damage under continuous vibration.
Typical Applications:
Heavy Machinery: Power switches, lighting controls, and accessory start/stop functions for excavators, loaders, cranes, and bulldozers.
Aerial Work Platforms: Its IP68 rating makes it ideal for use in platforms as the main power switch, hydraulic system start/stop switches, emergency stop backup switches, and travel control switches. It is ideally suited for outdoor and aerial work environments.
Power Generation Equipment and Construction Vehicles: Control panels for diesel generator sets, welding machines, forklifts, and other applications.
Marine Equipment and Agricultural Machinery: Industrial control applications requiring waterproof, dustproof, and corrosion-resistant features.
Industrial automation equipment: Automated production lines that require direct control of large currents and operate in harsh environments.
