Travel switch. But a member of the main electrical oh! Its action principle is similar to that of a button, but one difference is that it is not operated by hand, but by moving parts in mechanical equipment. It collides with its transmission part to make the contact of the travel switch operate. (Normally open contact. Closed, normally closed contact. Disconnect), so that you can achieve the purpose of breaking or switching the circuit!
When the travel switch works, it can open or close the circuit by colliding with internal components. In general, once the travel switch is turned on, it will give the machine movement. With a moving track, as long as the machine reaches the set position, it will automatically stop running, or change the motion state, so as to achieve the purpose of switching.
So, a travel switch is a device that controls machinery. Moving track of electrical appliances, make our life more convenient!
