MEMBRANE KEYPAD SWITCHES
The following are typical ratings and characteristics of a membrane keypad switch panels.
Actual performance depends upon many factors. IN2TEC routinely provides solutions to
design challenges - often working outside the bounds of these typical parameters. For
membrane keypad panel design assistance on specific applications, please consult your
local sales support.
TYPICAL RATINGS FOR EACH MEMBRANE SWITCH
- Minimum Current
- 50uA
- Typical Rating
- 1mA to 100mA
- Maximum Current
- 100mA (depending on life requirements)
- Circuit Voltage
- 100V (depending on circuit design)
- Circuit Resistance
- 1 ohm per 25mm for std width trace
- Switch Capacitance
- 10pF
- Switch Contact Bounce
- 10ms maximum
- Output Forms
- 1. Matrix (rows and columns)
- 2. Common line (common + no.of switches)
- 3. Customer specified configuration

- Switch Life
- Switch life varies tremendously from under 20K operations to over 50 million operations
depending on a wide range of factors including construction style, graphic layer material,
embossing, operating conditions, tactile feedback, and switch travel. Consult the factory for
information on a specific project.
- Panel Size
- Standard maximum panel size is 890mm x 590mm (35” x 23”).
- Standard minimum panel size is 14mm x 14mm (.55” x .55”).
- Tolerances
- Standard IN2TEC membrane manufacturing tolerance is +/-.25mm (.010”).
