Momentary switches shut off when you release them, thanks to an internal spring that returns the button to its default off position.

These differ from latching switches, which stay on until pressed again.

Key Types

  • Push-to-make (normally open) : Off until pressed; releases to off. Common in doorbells.
  • Push-to-break (normally closed) : On until pressed; releases to on. Less common.

How They Work

Inside, a spring mechanism activates only during the press, ensuring brief contact—like a car horn that stops when you let go.

Alternate (latching) switches "remember" the state without holding.

Type| Behavior on Release| Example Use
---|---|---
Momentary| Returns to off| Doorbells, car horns 37
Latching| Stays in position| Lights, power buttons 5
