Incorporates a tactile pushbutton along with a 10K pull-up resistor.
Description
The Tactile Pushbutton Switch Module incorporates a tactile pushbutton along with a built-in 10K pull-up resistor.
PACKAGE INCLUDES:
- Tactile Pushbutton Switch Module
KEY FEATURES OF TACTILE PUSHBUTTON SWITCH MODULE:
- Tactile pushbutton with good click action
- Built-in 10K pull-up resistor
The output of the module is normally HIGH (pulled up to Vcc) and pulled ground when the button is pressed (Active LOW).
The module has a built-in 10K pull-up resistor. To use this pull-up, Vcc should be connected to the center pin on the module. If input pull-ups are enabled on the MCU, this center pin can be left unconnected.
Module Connections
There is a 3-pin header on the assembly for making connections.
1 x 3 Header
- ‘-‘ = Ground
- Center pin = Vcc (3.3 – 5V typical) or leave unconnected if using input pull-ups on MCU
- S = Switch output. Connects to digital input pin on MCU
OUR EVALUATION RESULTS:
This is a basic module that can be used to experiment with button detection or to simply provide a button for a small project. Having a built-in pull-up resistor makes it a little more convenient to use than a bare button.
BEFORE THEY ARE SHIPPED, THESE MODULES ARE:
