Operating Point: Common contact transfers from normally closed contact to normally open contact. Overtravel: Distance plunger travels past operating point.

Understanding switch configurations

NC means normally-closed contact. NO means normally-open contact. When the relay coil is de-energized, NC contact becomes open, and NO contact closes. For alert and emergency shutdown (ESD) logic, a break-to-alarm philosophy is employed so that during an emergency, NC contact will become open and trip/provide alarm.

6 FAQs about [Energy storage normally open contact switch]

What is the difference between normally-open and normally-closed contacts?

Normally-open contacts are designated by the lines not touching, while normally-closed contacts are designated with a diagonal line bridging between the two lines. Compare the two: The switch on the left will close when actuated, and will be open while in the “normal” (unactuated) position.

What is normally open contact?

When a switch is in a normal position, the contacts of the switch remain either in the open or closed state as per its design. The contact of the switch that remains in an open position when it is not energized by manual or electrical force is called Normally open contact. The normally open contact is abbreviated as NO.

What are normally open and normally closed switch contacts?

Normally open and normally closed switch contacts are the terminology used to describe the open and close positions of the switch in normal conditions. Here, a normal condition is a condition when the switch is not energized manually or electrically.

Is a switch open or closed?

A switch is a binary device ( that has two states -0 or 1); they are either completely closed (On) or completely open (off). The switch has electrical contacts that can make and break the path of an electrical circuit. Electrical contacts are of two types- Open contact and Close contact.

What causes a switch to change from normally open to closed?

Normally open contact can change its state to a close position if the switch actuates by any type of energy, such as mechanical, pneumatic, hydraulic, or electrical. Thus, the actuation of the switch causes contact changeovers from the normally open to the closed position.

What is a normally closed vs normally open switch?

Normally closed (NC) and normally open (NO) contacts are terms used in the context of electrical switches and relays, but what’s the difference between a normally closed vs normally open switch? These terms describe the default state of a contact in a switch or relay when no external force or input is applied.
