A Membrane Keypad Has Many Advantages
Membrane keypads have found their usage in many areas. The membrane keypad is constructed from two thin plastic membranes. The membranes contain flexible printed circuit that is made of electrically conductive ink. Top membrane consists of a printed keypad followed by a bottom membrane that is used to complete the circuit.Almost every electronic gadget makes use of membrane keypads to perform specific functions. For instance, keypad membrane in a washing machine is used to set different washing levels, microwave oven keypads are used to set temperatures, garage door keypad is used on exterior parts of doors for locking the door. Membrane keypad technology has made its entry in the cell phone industry as well and they are quickly replacing other types of keypads.

There is no separate distinction of keys on this keypad. All the outlines and symbols are printed on a flat surface itself. The sleek and uniform design of a keypad membrane makes it aesthetically appealing, more tactile and easy to use. In addition to all these features, one of the major advantages of using the membrane keypad is its sealed surface. The sealed surface, further makes this keypad resistant to dust and water, hence increasing the life of the keypad.
