Frequently asked questions
How do I confirm which pins are connected?
Check continuity with a multimeter before wiring. Four-terminal tactile switches differ in how their pins are internally paired, so verify the arrangement with the datasheet or a test.
Can it be used on a breadboard?
No. It is a surface-mount part and must be soldered to a PCB or to an SMD breakout board.
