WebThe normally closed type or the normally open type can be chosen according to the duration of the continuous working time. 1. The normally closed solenoid valve is selected when the solenoid valve needs to be closed for a long time, and the closing time is longer than the opening time, and the continuous opening time is not very long. 2. WebA limit switch is a simple device. The lever is used to close a contact within the switch. When the contact is closed, it allows the electrical signal to go through. The mechanical operation is similar to that of a light switch. However, a spring is added to return the limit switch into its original position.
