How to Check the Quality and Safety of a Membrane Switch? Membrane switch production and requirement has seen a healthy spurt and with high gadget product and almost everything turning electronically operated, the requirement is even higher. Thankfully, along with the demand and production parties, there are organizations that make sure that feasible products are being designed and sold in the market. Membrane switch and graphic overlays are also subject such standard tests that help the buyers in making distinguished and informed decision about investing in safe and feasible switches. Distinct Membrane Switch testing standards are followed by reliable and quality manufacturer to test the quality of production and safety of the switches. It is indeed necessary to perform this testing as otherwise the produced switches may be inflammable or not follow the suitable tactile ratio or may suffer other design or operational error and further cause damage. Different test methods have been determined by the ASTM to test the switches on a range of parameters. Here are some of the methods that ASTM suggests manufacturers follow:
F1597 for the actuation and contact force F2357 for evaluation of coatings 'abrasion Resistance through Norman Tool RCA Abrader F1598 to learn the effects that exposure to chemical/solvent could have on a membrane switch/graphic overlay F1661 for evaluation of contact bounce time F1570 for membrane switches' tactile ratio F1663 for Capacitance F1680 for Circuit Resistance F1681 for conductor's Current Carrying Capacity (Switch Circuit) F1662 for verification of specified dielectric resistance voltage F1682 for switches' Travel F1689 for Insulation Resistance F1812 for ESD Shielding efficacy F1995 for Surface Mount Device's bond strength F1842 for Ink/Coating Adhesion switches' Plastic Substrates F1996 for Silver Migration F1997 for evaluation of tactile membrane switch's Sensitivity F2073 for Non-Destructive Short Circuit Testing F1896 for printed conductive materials' Electrical Resistivity
F2187 for Random Frequency Vibration effect F2188 for Variable Frequency Vibration effect F2359 for Backlit switch color through Diffuse Light Source F2360 for Luminance, etc
Manufacturers can check the ASTM guidelines for the technical and other testing standards for suitable membrane switch testing for more information on producing high quality and tested switches. Other than the standards listed by ASTM, global producers should also be sure about checking international guidelines and standards that they need to fulfill. A retailer should always sufficiently work hard to seek as much as information as they can find on the wholesaler. Producers who deal with global orders should not work on the intrinsic design of the switch with the buyer but also cover any necessary testing standards to avoid any damage later on. Buyers can also hire a consultant regarding the testing methods and then further check their shortlisted manufactures regarding quality of production. Moreover, by ensuring that the switches fulfill all necessary testing obligations, the buyers will be ensuring their own investment and safety of their products. The testing standards have been developed to improve the durability of the products so it's a must for every buyer to look into these before they make the final decision.
