Switches: Markings, Types, and Safety Considerations
Posted on 7/15/19 7:57 AM
From being used on a vacuum cleaner to being used on a life-support machine, the purpose of a switch is to open and close a circuit. A switch is used when incoming power in an electrical product design needs to be controlled. Opening a circuit (turning a device OFF) is achieved by breaking the connection. This interrupts the current flow. Closing the circuit (turning a device ON) allows the current to flow again.

Protecting Global Electrical Connections with Metric Strain Reliefs/Cable Glands
Posted on 7/1/19 9:47 AM
A strain relief or cable gland extends cord life and reinforces the cord connection to the equipment. The main purpose is to help protect the electrical connection and circuitry inside the equipment. The most common application is on a power cord providing electricity to equipment. In many situations, the equipment is portable and requires protection so the cable cannot be pulled out of the equipment.
