There are many applications of limit switches, and many electrical appliances have them. So what can such a simple switch do? It mainly plays a role of chain protection. The most common example is its application in washing machines and tape recorders (video recorders).

Once someone opens the door or cover of the washing machine, the motor is automatically cut off, and even mechanically linked, so that the door or cover will immediately "brake" and force it to rotate Stop the components to avoid personal injury.
In tape recorders and video recorders, we often use fast forward or rewind. The tape rotates rapidly, but it stops automatically when it reaches the end of the tape. Here the limit switch once again played a role, but this time it was caused not by a collision but by a sudden increase in the tension of the tape.
