Switches – whether micro-switches, tact switches, or rotational selectors – contain small, delicate internal components, such as springs, contacts, domes, and levers, all housed within a precision-molded casing. In high-use, vibration-prone, or high-shock environments (like automotive, industrial controls, or handheld devices), these tiny internal parts can shift, loosen, or dislodge, leading to intermittent operation, degraded feel, or complete functional failure. Precision bonding is essential to secure non-moving internal components and wire breakouts without affecting the mechanical action of the switch.
Don’t let minute component shifts cause catastrophic switch failure and costly device replacements.
INCURE GapFill™ D06 Low Viscosity Wicking Grade Cyanoacrylate Adhesive
The extremely tight tolerances and microscopic clearances inside a switch demand an adhesive that can flow into the smallest gaps and cure instantly without interfering with moving parts. INCURE GapFill™ D06 is a low-viscosity, wicking-grade cyanoacrylate designed to penetrate and lock components in place via capillary action. Its fast cure is critical for high-speed switch assembly.
| Feature & Benefit | Technical Insight for Switches | Conversion Value |
| Ultra-Low Viscosity (Wicking Grade) | Formulated to instantly flow into hair-line cracks and gaps (<0.05 mm) by capillary action, securing parts without requiring large, messy applications. | Surgical Precision: Lock internal springs, plastic posts, or wires in place without contaminating the contacts or switch mechanism. |
| Rapid Cure Time | Achieves fixturing strength in seconds, essential for high-volume manufacturing of small electronic and mechanical switches. | Maximize Production: Get instantaneous fixation, eliminating clamping and drastically accelerating assembly line speed. |
| Surface Insensitive Formulation | Bonds effectively to a wide range of materials common in switches, including specialized engineering plastics, metals, and ceramics. | Universal Bonding: Achieve reliable strength on all internal switch components, regardless of substrate composition. |
| High Strength, Rigid Bond | Cures to a tough, rigid plastic, creating a permanent anchor for static components and preventing migration or loosening from vibration. | Permanent Reliability: Ensure a robust, non-moving component for the entire lifespan of the switch. |
Application Steps: Securing Internal Switch Components
Preparation (Zero Tolerance): Since the tolerances are so tight, ensure any component being secured is perfectly positioned. Surfaces must be clean, dry, and free of any oils or plastic molding release agents.
Application (Wicking Technique): Using a micro-dispensing needle, apply a micro-dot of GapFill™ D06 to the edge or interface of the component you want to secure (e.g., the corner of a housing post or a wire jacket). Allow the adhesive to be drawn into the gap by capillary action. Do not apply directly to the joint.
Acceleration (If Needed): Due to the small bond area, an external activator spray (used sparingly) can ensure an almost instant cure. This prevents the low-viscosity adhesive from wicking into unintended areas.
Testing: Immediately verify the switch’s operational feel (click-force and travel) to confirm the low-viscosity adhesive did not penetrate and freeze the moving contacts or domes.
Ensure your electronic and mechanical controls maintain their original, flawless performance.
