12*12 SMD Waterproof Tact Switch

IP67 12*12 Tactile Switch's Product Structure and Operating Principle

12×12 waterproof tactile switches typically consist of the following components: Base and cover plate: Made of PA66 material, forming a sealed cavity through laser welding or ultrasonic welding to prevent moisture ingress. Metal Spring Contact: Serving as the core conductive component, made of phosphor bronze or stainless steel for high elasticity and fatigue resistance. Contact Point: Conductive contacts (e.g., silver-plated contacts) positioned beneath the spring contact connect to solder pads on the PCB to complete the circuit. Sealing Components: Such as silicone gaskets, waterproof O-rings, or secondary-molded insulating seals covering critical areas to block moisture ingress.

Work Process

Pressing Operation: When the user presses the switch surface, external force is transmitted through the cover plate to the metal spring leaf. The leaf deforms and depresses, causing the contact to engage with the PCB pad, thereby completing the circuit. 

Releasing Operation: After releasing the finger, the spring leaf returns to its original shape due to its inherent elasticity, causing the contact to disengage from the pad and break the circuit.

Waterproofing Process 

Sealed Chamber: The base and mounting slot form an enclosed space, sealed against external water ingress by a snap-fit waterproof membrane. 

Drainage Design: Select models feature drainage holes to prevent performance degradation from water accumulation. 

Humidity Monitoring: An integrated micro-humidity sensor continuously monitors humidity levels within the mounting slot, triggering an alarm mechanism when thresholds are exceeded.

12*12  Waterproof Touch Switch's Product Feature

1. Good feeling and long life; 2. Multiple operating force settings available; 3. Snap-in type, can be mounted directly on P. C. Board and good for electrostatic discharge; 4. It has a lot of choices for button shape and height and it is easily to install and kind of product; 5. The tactile switches/tact switch come with multiple cap and color options, excellent tactile feedback and high reliability dome technology.

The 12×12 waterproof tactile switch, with its larger contact area and enhanced structural strength, is better suited for scenarios requiring high reliability and large-sized buttons.

Large Appliances and Industrial EquipmentWashing Machines, Dishwashers: The 12×12 model, with its larger size and broader key contact area, is ideal for appliance control panels requiring frequent operation and waterproof/moisture-resistant performance. Its enhanced structural strength withstands prolonged pressing without damage. Outdoor Construction Machinery: Control panels for equipment like excavators and cranes must operate reliably in harsh environments (rain, mud, dust). The 12×12 model's waterproofing (e.g., IP67 rating) and durability (mechanical lifespan exceeding 100,000 cycles) meet these demands.Public Facilities & High-Load ScenariosSolar Street Lights & Outdoor Charging Stations: These devices endure prolonged outdoor exposure. The 12×12 model's waterproof and dustproof capabilities (IP67 rating) prevent rainwater ingress causing short circuits, while its large buttons facilitate user operation. Industrial Control Cabinets: Within factory automation systems, the 12×12 model is commonly used for emergency stop buttons or mode-switching controls. Its high reliability (withstand voltage of AC250V) ensures stable operation in high-voltage environments.Automotive Electronics & Harsh EnvironmentsEV Charging Systems: The 12×12 model's waterproofing prevents moisture ingress into charging ports during rain, while its oversized design facilitates easy plug-and-play operation. Marine Equipment: In humid shipboard environments, the 12×12 model's sealed construction (e.g., laser-welded enclosures) resists salt spray corrosion, extending service life.
