Using this push - type button switch sensor module is easy. First, connect the positive and ground pins properly to your power source. Then, you can connect the signal pin to your circuit. When you push the button, the signal pin will go high, and your circuit can detect this change. Just be careful not to exceed the maximum power of 600mW (50mA at 12v), or you might damage the module. To keep it in good condition, store it in a dry place and avoid exposing it to extreme temperatures. If you're using it on a breadboard, make sure the connections are firm.
