Tactile Pushbutton Switch Module

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:

• Sample inspected and tested per incoming shipment

Notes:
