Toggle switches are usually classified as either "make before break" contacts which will make contact when flicked in one direction, and break contact when flicked in the other, or "break before make", which will do the reverse. A123S1Y9W4B is a make before break toggle switch.

The typical applications of A123S1Y9W4B includes electrical equipment such as motor starters, heater control, light controls, and indicator lights. With a wide variety of uses, A123S1Y9W4B is commonly used in household and commercial appliances such as TVs, HVAC equipment, ovens and refrigerators. It can also be used in industrial control panels. In general, it is a versatile and reliable switch.

A123S1Y9W4B has a straightforward working principle. It is operated by a mechanical lever and flicking the switch from one direction to the other. When you turn it on, the switch contacts will make contact and send a signal for the appliance to power on.
