High-Reach 6x6mm Tactile Switch with Extended Cover | 12.5mm to 18mm Heights

Elevate your interface design with the Extended Height 6x6mm 4-Pin Tactile Switch from Pran Electronics Pvt. Ltd. Specifically engineered for deep-chassis applications, this switch features an additional protective cover/sleeve that supports stable actuation at extended heights ranging from 12.5mm up to 18mm.

Precision Engineering for Deep Enclosures

Standard tactile switches often struggle with mechanical stability when the actuator height increases. Pran Electronics solves this with a reinforced outer sleeve (cover). This design provides lateral support to the long-travel plunger, preventing “wobble” and ensuring a vertical, crisp click every time—even at an 18mm reach.

This switch is the ideal solution for products where the PCB is mounted deep within a thick plastic housing, such as Smart Meters, Industrial Control Panels, and Heavy-Duty Appliances.

Key Specifications

Why Choose the Extended Cover Series?

• No More Plunger Tilt: The additional cover acts as a guide rail for the long actuator, eliminating the “leaning” effect common in standard long-neck switches.

• Direct Enclosure Interface: With heights up to 18mm, you can eliminate the need for expensive plastic “extender” caps or secondary mechanical linkages.

• Enhanced Durability: The sleeve protects the internal dome mechanism from side-impact stress during assembly and operation.

• Stable 4-Pin Mounting: The standard 6x6mm 4-pin footprint ensures the switch remains anchored to the PCB despite the higher center of gravity.

• Pran Electronics Reliability: Manufactured using high-temperature resistant materials suitable for professional wave soldering.

Strategic Applications

This high-profile switch is a favorite among engineers designing:

• Smart Electricity & Gas Meters: Perfect for “Cover Open” detection or reset buttons in deep-set meter boxes.

• White Goods: Control panels for washing machines and ovens where thick insulation or fascia panels are used.

• Security Systems: Tamper-evident switches for thick-walled outdoor sirens and sensors.

• Set-Top Boxes & Routers: Front-panel power and reset buttons recessed behind thick aesthetic bezels.

Design Considerations

Pro Tip: When selecting the 18mm height, the additional cover significantly reduces mechanical fatigue on the solder joints by absorbing lateral user pressure. This makes it a much more robust choice than a standard long-plunger switch without a sleeve.
