Rocker Switches

The ST11L4S4V30QJ12 is a type of rocker switch that is used in many applications and is found to be a reliable and robust on/off switch. It has a unique design that allows for both tactile and audio feedback when in use. The ST11L4S4V30QJ12 is a versatile and cost-effective switch that is suitable for a variety of applications, such as controlling lights, appliances, or other electrical components. In this article, we’ll take a look at the application field and working principle of the ST11L4S4V30QJ12.

Application Field

The ST11L4S4V30QJ12 is designed to operate in a wide range of temperatures, from -30° Celsius to +80° Celsius, and is suited to both indoor and outdoor applications. It is usually found in control circuits, lighting systems, audio equipment, alarm systems, and many more applications. This switch is UL approved for use in the United States, Canada, and the United Kingdom.

The ST11L4S4V30QJ12 has been designed with a special feature that allows it to be used a quarter-turn/paddle-type switch. This type of switch is used in many high-voltage applications where a standard switch would not be able to handle the load. The switch is also rated for up to 6 amps of current, making it suitable for medium applications.

Working Principle

The ST11L4S4V30QJ12 works by using two metal contacts to connect and disconnect power to a circuit. When the switch is in its off position, the two contacts are separated and no current flows. When the switch is in its on position, the two contacts come together, connecting the power source to the circuit and allowing current to flow.

When the switch is operated, a special mechanism inside the switch causes a tactile and audible click to occur, providing both tactile and audio feedback that the switch has been operated. This feedback is also useful in applications such as alarm systems, where it is important to know that the switch has been operated accurately.

The ST11L4S4V30QJ12 also has a second switch mechanism that is designed to protect against accidental switching. This is done using two contactless switches, one on the front of the switch and one on the back. When the front switch is operated, the contactless switch on the back will allow current to flow and remain in its on position until the front switch is released. This provides an extra layer of protection against accidental switching.

Conclusion

The ST11L4S4V30QJ12 is a versatile, reliable, and cost-effective rocker switch. It is suitable for a wide range of applications, from lighting to audio equipment, and is rated for up to 6 amps of current. It has been designed with a unique switch mechanism that provides both tactile and audio feedback when operated, and a contactless switch mechanism that prevents accidental switching.
