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.
