Button Dimensions and Functions
0:26
Based on the available datasheet for KMR231NGLFS, here are some points:
-
Physical Dimensions:
The datasheet provided by C&K includes the mechanical dimensions (footprint outlines, overall length, width, and height) and the placement of gull wing contacts. You should consult the datasheet for the exact measurements. Typical SMD gull wing tactile switches are compact, often with dimensions in the range of a few millimeters on each side, but the exact numbers are listed in the datasheet. -
Function as Reset/Boot Button:
- Electrical Characteristics: This switch is a normally open, momentary tactile button rated for 0.05 A at 32 VDC.
- Usage Considerations: While it can serve as a reset or boot button in many microcontroller designs, reset (and boot) circuits often benefit from additional debouncing circuitry and proper interfacing (such as pull-up or pull-down resistors) to prevent false triggering.
- Recommendation: If you decide to use this switch as a reset or boot button, ensure that your circuit design meets the MCU’s requirements (e.g., proper voltage levels, debounce circuitry, etc.). In many cases, designers use dedicated reset switches that are optimized for that function, but this switch can work if these factors are taken into account.
For complete details on the dimensions, please refer to the KMR231NGLFS datasheet.
