ZB4BA4 is a line of 30mm metal push button switches made by Schneider Electric. They are designed to control electrical circuits and are equipped with convertible latching and momentary spring-return operation. They come with an illuminated chrome bezel, a black bezel, or two additional color bezels and come in a variety of colors and actuator shapes. The bezels are designed to protect the switches from hostile environments and many of the models are rated up to IP66/IP67 ingress protection. These switches are used in many applications such as industrial and commercial machinery, vending machines, and process control systems.
