Custom Electric Waterproof Keys Membrane Lexan Switch For Industry Controller

let's discuss the key design considerations for lexan membrane switches used in industrial controllers:
Material Selection

• Lexan (polycarbonate) is a common choice for the membrane material due to its excellent mechanical properties, durability, and transparency.
• Other materials like polyester may also be used depending on the application requirements.
• The membrane must be rated for the expected number of actuations over the product lifetime.

Tactile Feedback

• Providing consistent, well-defined tactile feedback is important for an intuitive user experience, even with industrial gloves.
• This involves careful design of the dome or button structure to achieve the desired actuation force and travel.
• Extensive testing is done to validate the tactile characteristics remain consistent.

Electrical Performance

• The membrane switch must provide reliable electrical contact and low electrical resistance.
• Design of the conductive inks or metal domes is critical to ensure consistent performance.
• Factors like contact force, wipe, and bounce are evaluated.

Environmental Resistance

• Industrial environments can be harsh, so the membrane must withstand exposure to chemicals, oils, moisture, temperature extremes, etc.
• Sealing the assembly to prevent ingress of contaminants is important.
• Accelerated environmental testing validates the switch can operate reliably in the target conditions.

Mounting and Integration

• The membrane switch must be designed to integrate seamlessly with the industrial controller enclosure.
• Considerations include alignment, attachment methods, and providing cut-outs for LED indicators.

Quality and Compliance

• Manufacturing in an ISO 9001 compliant facility with process controls is important.
• Depending on the application, the membrane switch may need to meet industry standards like UL, CE, or NEMA.
