Push the wheel at the front and that activates a switch that turns on the power. But sometimes we want electrical and electronic circuits to be activated in other ways. Suppose you want to wire up a bank safe so it triggers an alarm whenever the door opens. How would that work in ...
How To Wire A Float Switch? Float switches come in two wiring configurations; normally open and normally closed. Normally Open (NO) float switches are open when the liquid is below their activation threshold, meaning their electrical switch is disengaged and doesn’t conduct current. This is use...
Reed switches are normally rated to handle a maximum amount of current and voltage. But for electronic purposes, these most likely will never be exceeded, since reed switches normally can handle over 1 ampere of current and hundreds of volts, so this, again, is really no concern for electroni...
A relay is an electromagnetic switch operated by a relatively small electric current that can turn on or off a much larger electric current.The heart of a relay is an electromagnet (a coil of wire that becomes a temporary magnet when electricity flows through it). You can think of a relay...
How a Relay Works A relay consists of an electromagnet and a mechanical switch. Anelectromagnetis a simple device made up of a wire wound in a coil around a core of ferromagnetic material such as iron. This is a very interesting device and it is easy to build one yourself. All you need...
Step 2:Using a pair of pliers or wire cutters, cut the paperclip to match the size of the broken lock switch Step 3:Apply one drop of crazy glue (super glue) on the side of the clip press firmly on the spot where the lock switch was original. Be careful not to put too much glue...
The NI TB-2631B configures the NI PXI-2530B high-density matrix switch as a 4x32 (1-wire) or 4x16 (2-wire) matrix. It provides direct signal wire connections to the screw terminals inside the terminal block.Below is a summary of how to connect signals to a PXI-2531B using a TB-...

Add a thin wire (gauge 40 or such) to your design. Add a small hook or similar construction to your case that is guaranteed to pick up that wire when you close it. When you open it, the wire will snap and at any later power-up you can see that no current can ...
At the junction of each resistor and the reed switch solder wire of each color. They are 8 different. Solder a red wire to the copper ring of the reed switches as a positive and a black wire to the junction of all the resistors in the center of the "rosetta", as a negative. ...
