The Pololu Pushbutton Power Switch is an alternative to bulky mechanical switches. Small switch with big current ability!
Switches are funny things. They've been around forever, but are quite expensive, especially when designed to run higher DC currents. Pololu has developed this solution, that is small, tidy, and powerful - the Power Switch LV!
There are two versions, so be aware: this is the 2.5-7.0 V low-voltage version, there's also the Standard 4.5-20V voltage version available.
Originally intended as a DC power switch for small robots, it offers optimizations, but with a few limitations:
Benefits over mechanical switches:
Drawbacks compared to mechanical switches:
