Contact Configuration

NO/NC Options

You need to understand the two main contact configurations when you choose a Push Button for your system. These are Normally Open (NO) and Normally Closed (NC). Each type works differently and fits specific functions in control panels.

Here is a simple table that shows how NO and NC contacts operate:

You use NO contacts for start or go commands. When you press the button, the circuit closes and current flows. This setup works well for machines that need a momentary signal. NC contacts suit stop or emergency stop functions. The circuit stays closed until you press the button, which breaks the connection and stops the machine. This design helps keep your system safe because any loss of actuator will open the circuit and trigger a stop.

Tip: Always match the contact type to your application. This step improves safety and reliability.

Switching Logic

Switching logic describes how the contacts change state when you press the button. You need to know if your system requires a single contact or multiple contacts working together. Some Push Button assemblies offer both NO and NC contacts in one unit. This feature lets you control two actions at once, such as starting one device and stopping another.

You can use switching logic to create complex control schemes. For example, you might wire an NO contact to start a motor and an NC contact to stop a safety alarm. You should check the wiring diagram and make sure the logic matches your control needs.
