what is a momentary switch

A momentary switch is a type of switch that only remains in its on state as long as it is being actuated, such as being pressed or held down. Once the actuation is released, the switch automatically returns to its default "off" position. This is in contrast to a latching switch, which remains in its current state until manually changed. Momentary switches are spring-loaded to return to their original position once pressure or force is removed. They are useful for performing specific actions or functions only momentarily, such as initiating a short burst of electrical activity or triggering a response in an electronic system. Momentary switches are commonly used in intercoms, lighting products, doorbells, and other applications requiring precise timing and control. Examples of momentary switches include push-button switches, which are the classic momentary switch and typically have a tactile "clicky" feedback when pressed.
