The Importance of Using Membrane Switch Tester A switch is an integral part of electrical or electronic equipment. It is used to turn an equipment on or off by establishing or terminating circuit by momentarily interrupting it. One of the most widely used switches among them is the membrane switch. Being smaller in size they save considerable amount of space and are ideal for smaller equipment and Print Circuit Boards. However, it is important that these are expertly designed with high-precision and are meticulously tested with membrane switch tester technologies. A membrane switch finds use in many commonly used household equipment including coffee making machines or microwave ovens. Healthcare, automobile and many other industries use them in their machines and equipment. The basic structure of a membrane switch
Some of the materials commonly used for manufacturing membrane switches are metals, copper and plastic. It is basically a circuit printed over a thin ITO or polyester film. The topmost layer serves as a protective layer to the user. This layer is made of graphic overlay which is attractively designed with impressive graphics, colors and text. It is also used for branding purposes. The role of the remaining layers is to offer durability and enhance the performance of the equipment. Membrane switches are made of polyester to add to its durability and improve its performance. Different types of membrane switch testing Membrane switch testing plays a vital role in ensuring that the product is of top quality with high level of durability in different kinds of adverse conditions. Extensive testing is used to make sure that the membrane switch can withstand varying pressure, heat, humidity, abrasion, etc. Following are a few types of testing done: 
Actuation tester is used to test the life of a switch.
Actuation Force Gauge is used to test the tolerance level of the actuation force of the switch. Environmental Test Chambers are used to test the products in varying temperatures and humidity. Specialized UV Chambers are used to test the products tolerance against an extended exposure to Ultra Violet rays.
Choosing the right manufacturer
A number of companies manufacture membrane switches and graphic overlays for different types of equipment. Of course, all of them claim to be the best and offer you the best quality products. However, it is important to make sure that they truly live up to the standards they proclaim. In order for a membrane switch manufacturing company to reach a high standard of service, it is essential that it has the knowledge and expertise to match it. Things to consider while selecting the manufacturer One of the most important factors to consider while selecting the right manufacturer is whether they offer a customized solution for client’s requirements. They should also offer extensive quality testing facilities using high-end membrane switch tester techniques and technologies. Using technologies like the lifecycle testing equipment can ensure that the products match the desired high standards of durability. It is also important that they offer cost-effective solutions by minimizing the production cost, optimizing the performance of the products at a reasonable cost. It never hurts to have some background information about the membrane switch manufacturers. Their past performance and their customer support are important points to consider. Obtaining some feedback from past customers and their experience with the products as well as the company is a great way to zero-in on the best manufacturer.
