This breadboard-compatible module is an alternative to bulky power switches. It uses a small integrated slide switch to control a high-side power MOSFET that can deliver continuous currents up to around 16 A at 4.5 V to 40 V. The board features reverse-voltage protection and also makes it easy to control the MOSFET with an external switch or the digital output of a microcontroller.

Pololu 5652 is an adapter that allows connection of 3-wire JST PH and SH connectors to circuits with 2.54 mm pin headers. Applications include sensors, communication modules, and servo systems. The adapter is a convenient tool for quick integration of wires with prototyping boards.

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.
