The YESWITCH HT802 series is a high-performance, high-current, double-pole (dual-way) toggle switch designed for harsh industrial environments. Its core design philosophy focuses on high reliability, superior electrical performance, and unparalleled environmental adaptability. This series features integrated dual (ON)-ON-ON reset functionality, a rugged locking metal handle, reliable screw terminal connections, and the highest IP68 protection rating, making it an ideal component for controlling critical circuits in equipment such as heavy machinery and aerial work platforms. It can withstand extreme operating conditions such as high current, high vibration, dust, and moisture.
Core Features
Unique Dual (ON)-ON-ON Reset Function (DPDT Center-Off Momentary)
Dual (DPDT): refers to a switch with a double-pole, double-throw (DPDT) structure. This means a single switch can independently control two circuits simultaneously, equivalent to the synchronized operation of two single-pole, double-throw (SPDT) switches. This significantly improves wiring efficiency and space utilization.
(ON)-ON-ON): Describes the switch's operating position. It has three active positions:
Reset (Momentary): This is the key to this function. It typically refers to both ON and OFF positions being momentary. That is, when you push the handle to the left or right, the circuit is connected. Once you release the handle, the internal spring automatically returns it to the center OFF position, disconnecting the circuit.
Application Advantages: This trigger-reset mechanism is ideal for applications requiring inching control or preventing accidental operation. For example, on an aerial work platform, the operator activates the equipment (such as raising or lowering the platform) when they press the switch, and stops when they release it, greatly enhancing safety.
Locking Metal Lever
Durable: The handle is made of high-quality metal, which offers greater mechanical strength, impact resistance, and torsion resistance than plastic handles, making it durable enough to withstand frequent and rough operation.
Anti-Incorrect Operation: The classic locking design requires a finger to lift or press the handle to activate the lever, effectively preventing accidental operation due to accidental collisions or scratches on clothing, ensuring the safety of both equipment and personnel. User-friendly Operation: Even wearing heavy gloves (common with construction machinery), this ergonomically designed switch allows for easy and accurate operation.
Screw Terminal Connection
Reliable Connection: A robust screw terminal provides strong and stable mechanical clamping force and electrical contact area, preventing vibration-induced wire loosening, disconnection, or poor contact, which could cause power outages, sparks, and other malfunctions.
Versatile: It can connect wires of varying diameters and provides superior current-carrying capacity.
Easy Maintenance: Installation and subsequent maintenance wiring are easy, requiring only a standard screwdriver, making it suitable for on-site installation and repair.
IP68 Protection Rating
Fully Protected: IP68 is the highest dust and water resistance rating for electrical equipment enclosures.
Environmental Adaptability: This means the HT802 switch can withstand outdoor rain, snow, washing and disinfection, dusty environments (such as construction sites and mines), and extremely humid environments, ensuring internal contacts remain free of contamination and long-term stable electrical performance.
16A High Current Rating
Powerful Drive: The 16A rated current enables direct control of high-power loads such as lighting, motors, solenoid valves, and water pumps, eliminating the need for intermediate relays. This simplifies the control system structure, reduces costs, and reduces potential failure points.
High-Performance Contacts: Utilizing high-quality contact materials such as silver alloy, this ensures effective arc suppression even during high current switching, reduces contact resistance, and extends the switch's electrical life.
Typical Applications
Aerial Work Platforms: Used to control inching operations for core movements such as platform raising and lowering, and telescoping booms. Its reset function and anti-error features are essential safety regulations.
Heavy Engineering Machinery: Used on excavators, loaders, cranes, and other equipment for switching functions such as attachment control (hydraulic hammers, grabs), lighting systems, and preheating.
Special Vehicles & Agricultural Machinery: Controls various operating devices on tractors, harvesters, and fire trucks. Industrial Equipment & Automation: Used in applications requiring manual override, mode switching, or emergency control.
Marine Equipment & Outdoor Enclosures: Its IP68 rating perfectly withstands wet decks, salt spray environments, or condensation in outdoor enclosures.
The YESWITCH HT802 series high-current toggle switches are more than just a simple on/off element; it is a sophisticated control interface designed for extremely reliable and safety-critical industrial environments. Combining dual-circuit control, instantaneous reset, metal lockout, high-reliability connections, extreme sealing, and high current carrying capacity, it offers heavy equipment manufacturers a premium option that enhances overall safety, durability, and professionalism. It is the confident choice for engineers designing critical control systems.
