Emboss Type Membrane Switch With LED Light For Testing Controller


let's discuss the key testing considerations for an industrial controller membrane switch:
Electrical Testing

• Validate the electrical performance of the membrane switch, including:
  • Contact resistance - Ensure low, consistent resistance when actuated
  • Electrical life - Test for the required number of actuations without failure
  • Dielectric strength - Verify insulation can withstand the expected voltages
• Use specialized test equipment like multimeters, LCR meters, and high-voltage testers.

Tactile Testing

• Evaluate the tactile feedback characteristics, such as:
  • Actuation force - Measure the force required to actuate the switch
  • Travel distance - Verify the button/dome travel meets specifications
  • Tactile response - Ensure a clean, consistent "click" feeling
• Use custom test fixtures with force gauges to measure these parameters.

Environmental Testing

• Subject the membrane switch to environmental stresses to validate reliability:
  • Temperature cycling - Test from min to max temperatures
  • Humidity exposure - Evaluate performance in high humidity conditions
  • Chemical exposure - Verify resistance to common industrial chemicals
  • Ingress protection - Validate the switch meets the required IP rating
• Use specialized environmental test chambers for these evaluations.

Durability Testing

• Perform lifecycle testing to ensure the switch can withstand the expected number of actuations:
  • Automated test equipment can cycle the switch hundreds of thousands of times
  • Monitor for contact degradation, mechanical failure, or other issues
• Accelerated life testing can predict the switch's lifespan.

Quality Inspection

• Visually inspect the membrane switch components and assembly for defects.
• Review manufacturing records and test data to ensure compliance.
• Document all testing and inspection results in a design history file.

Membrane switch Performance Index

Product spec :

1)Material---for front or face overlay
Polyester
1.Highly versatile for embossing 2.Highly resistant to chemicals

3.Better durability 4.For internal and external use
Polycarbonate
1.Wide range of surface finishes and thicknesses
2.More cost-effective 3.For internal and external use
2) Embossing--rim embossing pillow embossing dim embpssing
Graphic overlays can be embossed in order to insert domes (tactile), leave space for mechanical keys and provide tactile indications Pedestal embossing
3)Windows ----for display function
1. print colors windows
2.transparent finishes windows
4)Keys/buttons
Tactile keys---with metal dome or poly dome
Non-tactile--silver printing spot
5) Embeded LEDs-
miniature LED, LED colors:white, yellow, orange, green, red, etc.
6)Cable
is an extension of the printed circuit and is used to communicate with your device
7)Types of connector
1.Zero insertion force (ZIF) connector; 2.Female connector; 3.male connector
8) EMI / RFI / ESD Shielding
use an aluminum foil shielding / a clear ITO electrical conductive polyester
9) Adhesive ----mostly used are 3M-double-side glue
10)Backplate---in aluminum, polycarbonate or acrylic
