Membrane switches are widely used in industrial, mechanical, electronic,
medical, instruments, meters, household electrical appliances, and many
other areas
Membrane switches have many advantages over other switches. They are
thin and compact, have a low cost, are versatile and durable, user friendly
and are moisture and dirt resistant. Additionally, they come in many
visually-pleasing styles and colors suitable for any need.
Membrane switches, also called membrane keypad, are built from thin
polyester film and pressure sensitive adhesive (PSA). Printed Circuit
Boards (PCBs) can also be used as the base for a switch. Membrane
switches can be tactile or non-tactile, depending on the design. Tactile
switches provide a physical ¡°click¡± when the user pushes it.
Non-tactile switches have longer lives, but lack physical feedback to the user.
Rubber keypads can be added to the top of the membrane switch as well.
