12 mm Momentary On/Off Reset Push Button

This is a 12 mm push‑button switch that is momentary: the circuit is only on while the button is held down; when you release it, the circuit turns off. The button is typically used as a “start” or “trigger” switch (for example, to pulse a motor, buzzer, or test circuit), rather than a latching power switch.

Basic operation

• Momentary action: Press once → power on; release → power off automatically.
• Common configurations are normally open (NO), so the contacts close only when the button is pressed.

Physical details

• Size: 12 mm diameter, designed to fit into a matching panel‑cut hole.
• Typically has a metal or plastic button on a plastic body, suitable for breadboard‑style enclosures or small panels.

Note: Exact current rating and pin layout depend on the specific model; check the datasheet for safe usage.
