Description

The Pololu Pushbutton Power Switches are sophisticated power control alternatives to bulky mechanical switches. The main function is pushbutton-based latching power control, where one push turns on power and another push turns it off. Additional control inputs allow advanced applications such as automatic shutdown by the device being powered. This standard-voltage (SV) version operates from 4.5 V to 40 V and can deliver continuous currents up to around 4 A.
