This KY-004 3 Pin Button Key Switch Sensor Module For Arduino is ideally suited to add a button to your projects and gives a high signal when it is pressed.
The module of the push button is a fully-fledged device with which you can install it immediately in the project, without using a pull-up or tightening resistances, because this is already in the circuit. The button together with the resistor is located on the board, where there are holes for installation. The built-in resistor has a rating of 10 kΩ.
The module is designed for two contacts: when pressed, they are closed and open when released. There are also 3 outputs on the board: I, S, + 5V. Contact I is connected to the common wire of the circuit, S is the output of the module and + 5V is connected to the power supply.
