This is a simple SPDT slide switch - great for use as an ON/OFF button, or just as a general control switch. The pins are spaced by 0.1", however they are incredibly thin making breadboard use not recommended. The switch is rated for 0.3A at 50VDC. This switch is just a bit smaller than our popular SPDT Mini Power Switch, but uses the same pin spacing. Being smaller takes up less PCB space (good!), but it does make it a bit harder to hit and flip easily. Documents: Dimensional Drawing ...

This is a glass ferrule type fuse. It fits great with our 5mm fuse clips. The fuse is rated for 125VAC, up to 5A. Fuses are pretty simple, if more than 5A pass through the fuse, the small filament inside the fuse heats up and breaks (like a light bulb burning out). The circuit is then broken and hopefully your circuit is saved from molten destruction. For smaller loads, you may want to checkout a PTC (aka resettable fuse) listed below. These handle less current (500mA) but can be set and reset...
