Product Overview
The Self-Locking Push Button Switch 6-Pin from Pro Tronix is a staple for every electronics workbench. Unlike momentary buttons that spring back immediately, this switch features a self-locking (latching) mechanism: press it once to turn it ON (the button stays down), and press it again to turn it OFF (the button pops back up).
With its 6-pin DPDT (Double Pole Double Throw) configuration, it can control two separate circuits simultaneously or be used to switch between two different power sources. Its pin pitch is designed to fit perfectly into standard breadboards and 0.1″ pitch prototyping boards, making it the go-to choice for Arduino and ESP32 power management.

Key Features
Breadboard Ready: Long, thin pins allow for easy insertion into breadboards without the need for soldering or adapters.
Dual-Pole Control: The 6-pin layout allows you to disconnect both the Positive and Negative lines at once for complete circuit isolation.
Reliable Latching Action: Pro Tronix ensures a smooth mechanical transition with a clear “click” that locks the button firmly in place.
Small Footprint: Its vertical design saves valuable board space while remaining easy to operate by hand.
Common Applications
Project Power Switches: The primary ON/OFF switch for battery-operated breadboard prototypes.
Mode Selection: Switching a circuit between “Programming Mode” and “Run Mode.”
Signal Routing: Toggling between two different sensor inputs or output paths in a logic circuit.
Educational Kits: Teaching students the difference between momentary and latching switch behaviors.
