Product information
Punch your secret key into this numeric membrane keypad. This keypad has 4 buttons, and since every key has its own wire line, no matrix code is required - just treat these like every day switches. The membrane is soft and has a removable paper backing to expose a strong adhesive so you can stick this on an enclosure and feed the cable through a slot. Its a simple keypad but that's why we like it.

Our bilge pump float switch is safer than mercury switches, this switch utilizes a mercury-free rolling ball mechanism and includes an exclusive anti-spike feature to prevent the rapid on/off cycling encountered with some switches. Made of rugged thermoplastic. Universal design works with all 12V, 24V and 32V bilge pumps.
A bilge pump float switch is a smart device used in boats that turns on a bilge pump when the water in the bilge reaches a certain level. It is a must-have in any boat that is left unattended for any length of time, as all boats tend to leak at least some water. This switch is submerged, so you need to waterproof the electrical connections and hang the wires to ensure they stay as dry as possible.

RASPBERRY PI BOARD NOT INCLUDED
Whether you're pulling-up or pulling-down, there's no need to frown! With the PUD board from ModMyPi, adding multiple pull-up or pull-down resistors to your Raspberry Pi project is easy!
If you want to detect an "output" with your Raspberry Pi, like a button being pressed or a motion sensor detecting movement, we can configure our Raspberry Pi's GPIO pin as an "input". That input pin can be in three states (known as Tri-State logic); "high", when 3.3V is applied, "low", when the pin is connected to 0V, and "floating" when the state is undefined. Floating voltages are troublesome in electronics as the input can either read high or low depending on various fluctuations in electrical noise. Like a gate flapping open and closed in the wind, someone needs to lock the gate closed, or wedge it open. If you leave it flapping, it's likely to hit someone on their bottom on the way through!
Like our gate, the best way to avoid a floating input is to "tie" your input pin either high or low to create a default state. This is usually achieved through the use of a pull-up or pull-down resistor, either connecting our input pin via a resistor to the Pi's 3.3V to achieve a 3.3V high state, or the GND line to achieve 0V low state.
Our PUD board takes the messy wiring out of adding a pull-up or pull-down resistor to your circuit. Simply wire up the sensor output to the single pin on the PUD board and add a shunt jumper to either pull up (u) or down (d)! Therefore when you apply a signal voltage from your sensor or switch, the Pi is easily able to sense into which logic state the pin has been pulled! No more trouble from floating I/O's!
The PUD boards connects across GPIO pins 11 to 18 (17 to 24 in BCM speak), and adds a jumper configurable pull-up or pull-down resistor to each GPIO pin: 11 (BCM 17), 12 (BCM 18), 13 (BCM 27), 15 (BCM 22), 16 (BCM 23) and 18 (BCM 24). Pin 17 (3.3V) & pin 14 (GND) are used to tie the pins!
The PUD Board Features:
- Add a pull-up or pull-down resistor to your GPIO with the swap of a jumper!
- Compatible with all Raspberry Pi Models Inc. A+/B+/2/3 & Zero/ZeroW
- Tiny board means it's easy to integrate into any circuit - takes up just 8 GPIO pins
- Connects across GPIO pins 11 to 18 inclusive (BCM 17 to 24)
- In-line 1kΩ current limiting resistors on each GPIO
- 10kΩ pull-up or pull-down resistors on each GPIO
- All 6 GPIO pins can be configured independently
- Includes 6 x 2 Pin Shunt Jumpers & 1 x PUD Board
- Jumper configurable pull-up or pull-down resistor on pins:
- 11 (BCM 17)
- 12 (BCM 18)
- 13 (BCM 27)
- 15 (BCM 22)
- 16 (BCM 23)
- 18 (BCM 24).
- Pin 17 (3.3V) & Pin 14 (GND) are used to tie the pins!
- To pull pin up, connect the jumper across "u" and the center pin
- To pull pin down, connect the jumper across "d" and the center pin

Pi Supply Switch Features:
- Pi Supply Switch printed circuit board (PCB) v1.1
- All through hole components for assembly
- Flat USB noodle cable
- Two free Pi Supply stickers
- Comes as a kit - easy assembly with some basic soldering
How does it work?
Once you have finished using your Raspberry Pi, you just shutdown using the sudo halt command, and then a couple of minutes after the full and safe shutdown the Pi Supply Switch cuts the power to the computer. From this point, once again, all you would need to do to restore power to the Pi is touch the on button.
There is also a hard power off button for use in emergencies which immediately cuts the power to your Raspberry Pi. Remember to only use this button when absolutely necessary (e.g. Pi has been frozen for a long time) as it risks corruption of the files on your SD card if done at the wrong moment.
What makes the Pi Supply Switch superior to other makeshift solutions available is that it allows you to restart the Raspberry Pi using the sudo reboot command without the power turning itself off. Perfect!
Putting it together
We have made the Pi Supply Switch a self-solder kit which is quick and simple to put together ? even for an absolute beginner to electronics. This means as well as being a nifty little bit of kit to manage your Pi?s power, it is also a great intro to electronics and soldering. As you can see from the pictures the input and output of the switch is fed by a standard USB connection. We even provide you with the USB cable. Once soldered together, is essentially ?plug-and-play? with your existing ?wall wart? power supply unit. We have even packaged the circuit into a small profile so that it fits neatly into your workstation. The Pi Supply Switch is an essential piece of kit for all Raspberry Pi users!Resources
