What is a snap action?
What will be an ideal response?
Almost all sensing devices employ a snap-action switch. When a mechanical switch is used, the snap action is generally obtained by spring loading the contacts. This snap action is necessary to ensure good contact when the switch operates. Assume that a float switch is used to sense when water reaches a certain level in a tank. If the water rises at a slow rate, the contacts will come together at a slow rate, resulting in a poor connection. However, if the contacts are spring loaded, when the water reaches a certain level, the contacts will snap from one position to another.
