Push Button Tactile Micro Switch PTM/RTB 0.05A 12VDC

A press button, also known as a push button, is a mechanical or electrical switch that is activated by pushing a button. It’s a common way to control electrical circuits, initiate actions on machines, or interact with various devices. Press buttons are primarily used to control electrical circuits by opening or closing them, or to trigger a specific action on a device. They come in various forms, including momentary (where the circuit is only on while the button is pressed) and latching (where the circuit stays on after the button is released). When a press button is pushed, it actuates an internal switching mechanism, either making or breaking contact within the electrical circuit, or triggering a desired action.

A push button where the circuit is broken when the button is not pressed and closed (circuit connected) when pressed.

A push button where the circuit is closed (circuit connected) when the button is not pressed and broken (circuit open) when pressed.

SPST: Single Pole Single Throw

SPDT: Single Pole Double Throw

DPST: Double Pole Single Throw

DPDT: Double Pole Double Throw

PTM/RTB: Push To Make/Release To Break

These terms refer to the number of poles and throws in the switch, describing the electrical circuitry.
