Andux Land Round Switch ON/Off Push Button Switch 12mm Thread 20pcs ANKG-03 -Latching Type Black Cap-

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. A latching switch is a switch that maintains its state after being activated. A push-to-make, push-to-break switch would therefore be a latching switch - each time you actuate it, whichever state the switch is left in will persist until the switch is actuated again. 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.
