Rangvishwa Enterprises

This keypad has 12 buttons arranged in a 3 x 4 pattern. Simple to use, Accurate, serial and parallel output available. You can access by serial interface or 4bit parallel interface.Thenumber pad is similar to that found on a telephone. Any of the output can be used for interfacing. The connector uses a standard breadboard pitch (0.100” / 2.54mm) and can be used with the standard Arduino UART Library found in the Arduino IDE. The data is given on the output as the button is touched. It can be integrated with any existing system easily.

FEATURES:

1.      Simple to Use, Auto Calibration

2.     Easy to replace mechanical key

3.     Output can be directly connected to Microcontroller's Input pins

4.     Standard breadboard pitch (0.100” / 2.54mm)

5.     Works with built in Arduino library

6.     Adhesive backing, if require.

7.     Acrylic or Polycarbonate based fascia available.

In these type of membrane switch, a rigid glass epoxy printed circuit board(PCB) is used. It is easy to add of other components like LEDs, resistors and apply a graphics layer directly onto a PCB. We offer PCB range from 0.4 mm to 3.2 mm and the board can be single-sided, double-sided or multi-layer as per the customers requirements. A PCB allows components soldered directly to the board and provide a wide and more Connector locations, depending on the complexity of the design. Inbuilt, use a Mounting screw to fix LCD, Display PCB & Keyboards. In these we can also provide ESD sheilding.

These types of membrane switches does not contain any machnical dome switche, also called as Non-Tactile Membrane Switches

The switches that can bend, move and twist without damaging the conductor and utilized where flexibility required. We offer small sized, thin, lightweight, shock and abrasion resistant and convenient in installation and connection Flexible membrane switches. Rangvishwa manufacture these switches with the latest technology and superfine material for better performance and longer duration. These switches are used in the ultrasound probe, medical device, industrial equipment, manufacturing equipment, aerospace industry etc. These switches made from layers of flexible polyester sheets bonded together with thin adhesive sheets. In the Flexible Membrane Switches, screen printing creates the electrical circuitry through the conductive ink on the polyester layers forming traces (that act like wires) and contact pads in the key areas. After the assembly, the membrane switch components form an electrical device containing one or more touch switches.
