Pushbutton switches are commonly used in a variety of applications, including industrial and commercial automation, medical equipment, and aviation. The 40-4743-00 is a popular pushbutton switch model produced by Eaton, a leading manufacturer of component parts for the electrical and industrial markets. This basic pushbutton switch is single pole, single throw (SPST) which means it completes the electrical (or mechanical) circuit when the button is pressed. It is rated at 10A at 250 VAC, 50/60Hz and is available in both single-button and double-button models.

The 40-4743-00 pushbutton switch can be used in a wide variety of applications, such as lighting and alarms, elevator controls, Automatic equipment, or any application where a momentary switch is required. It is also commonly used as a back-up contact in circuit breakers, allowing control of the breaker remotely. The contact is made of silver which is ideal for low voltage and current applications, and offers superior contact resistance and long life.

The basic working principle of the 40-4743-00 pushbutton switch is straightforward: when the button is pressed, an electrical connection is completed. This allows current to flow from the power source to the load. The switch is bi-stable, meaning it locks into either the “on” or “off” position until the button is pushed again. If a fault occurs, the switch will switch to the “off” state, preventing any further current from flowing.

The 40-4743-00 pushbutton switch is a durable and reliable switch that can be used in a variety of applications. Its simple operation and long lifespan make it an ideal switch choice for many industries. In addition, Eaton offers a wide range of accessories that can be used with this switch, including protective shrouds, pilot lights, backlighting, and panels. This makes it easy to customize the switch to your specific application needs.
