Andux Land Square Switch Momentary Type Push Button Switches 12mm 5pcs ANKG-05 -Different Color-

A push button is a momentary or non-latching switch which causes a temporary change in the state of an electrical circuit only while the switch is physically actuated. An automatic mechanism (such as a spring) returns the switch to its default position immediately afterwards, restoring the initial circuit condition. Note: The terminals are very small, need to be very careful when soldering the wires on to them. Recommended solder within 3 seconds. Installation instruction and wiring diagram are not included in the package. Professional installation is highly recommended.
