2519-POLOLU Dual MAX14870 Motor Driver Shield for Arduino
US$37.42
This small shield is an easy, economical way to control two small brushed DC motors with an Arduino or Arduino-compatible board. Its two integrated MAX14870 motor drivers allows it to operate from 4.5 V to 36 V, making it a great for higher-voltage motors and applications, and the shield can 1.7 A continuous (2.5 A peak) per motor. The shield can optionally be configured to power the Arduino from the same power supply as the motor driver, and the Arduino pin mappings can be customized (by cutting traces) if the defaults are not convenient.

DRI0044-A 2x1.2A DC Motor Driver with Gravity Connector (TB6612FNG)
US$13.83
This DFRobot micro dual way DC motor driver with Gravity connector. It is design based on TB6612FNG motor driver chip. It inherits DFRobot L298N motor control logic, which only need four pins to drive 2 motors. The Gravity connector version expands four GPIO with standard Gravity connector. Once you use the Gravity IO Expansion board (DFR0265), it will be quite convenient. TB6612FNG is a dual-channel full-bridge drive chip. The maximum continuous drive current of single channel can reach 1.2A, peak value 2A/3.2A (continuous pulse / single pulse) , which can drive some micro DC motors. The control logic is similar to L298n, and the code can be directly compatible with the DFROBOT L298N motor driver. Standard XH2.54 pin can be inserted directly into the breadboard. It is a good choice for DIY project or product developments. If you need some tiny module, you can also use the TB6612FNG (DRI0044) module separately.

DRI0044 2x1.2A DC Motor Driver (TB6612FNG)
US$7.88
This DFRobot micro dual way DC motor driver is design based on TB6612FNG motor driver IC. It inherits DFRobot L298N motor control logic, which only need four pins to drive 2 motors. Compared with the IC Breakout, it saves two precious GPIO resource, especially in Arduino UNO board. TB612FNG is a dual-channel full-bridge drive chip. The maximum continuous drive current of single channel can reach 1.2A, peak value 2A/3.2A (continuous pulse / single pulse) , which can drive some micro DC motors.

PBS-LED-200RD 12V 16mm with Red LED Ring Waterproof Latching Pushbutton Switch
US$6.99
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 switches will stay in this position until the button is push again. 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 12VDC to the LED ring to have it light up nicely, there's a built in resistor!

SEC-90 Embedded Normally-Closed Contact Magnetic Switch for Access Control
US$2.23

Recessed magnetic door switches are made with the same magnetic reed switches used for surface-mount alarm contacts. Instead of a rectangular housing, recessed alarm contacts have a cylindrical case. This makes them easy to install, just by drilling a hole of the proper diameter. The magnets are also designed with the same type of cylindrical housing.
