PBS-LED-2206BL-L, 3-6V 22mm Waterproof Latching Pushbutton Switch with Blue LED Ring
US$8.00
These illuminated waterproof chrome-plated metal pushbuttons give a professional appearance to any project. When you press it the 'normally-open' contact shorts to the common contact and the ‘normally closed’ contact button opens. The contacts will stay in this position momentarily until the button is released. Waterproofing is provided with a rubber O-ring. On the front of the button is a flat metal actuator, surrounded by a plastic LED ring. On the back there are 3 contacts for the switch; C (common), NO (normally open) and NC (normally closed) and 2 contacts for the LED ring (+ and -). Connect 3-6VDC to the LED ring to have it light up nicely, there's a built in resistor!

AM-121 Active Buzzer Module
US$1.99

The KY-012 active piezo buzzer is a 3-pin module that creates an audible sound at 2.5 kHz without the need for pulse width modulation (PWM) or any additional complex code. The only requirement is to set the signal pin to HIGH.  If you’re looking for a simple but effective way to build audio into an Electronics or Arduino project, the KY-012 Active Buzzer Module is a great choice, and is designed to simply produce a single-tone sound when the incoming signal is high. This allows for single-pin operation on an Arduino Board, which is perfect for building a custom alarm or detection system that can send out an audible signal when it receives the electronic high signal from the Arduino controller board.
