Rocker switches are an incredibly useful electrical component with a wide range of applications in a number of industries.WR13AL/CUL is an versatile and affordable rocker-switch offered by Legrand. This article looks at the WR13AL/CUL switch, its applications, and its underlying working principle.

Construction and Design

The WR13AL/CUL switch is a rocker switch that enables single pole, single throw control of an electrical circuit. It has an outer frame made from UL 94V-0 flame retardant plastic, which is highly resistant to heat, fire, and chemicals. The frame comes in two colors: white and light almond. Inside, two openings for rocker actuation provide two metallic contacts which connect to a circuit when the rocker is in either the up or the down position. The silver tips of these metal contacts are made of tin-plated silver.

The switch is rated for 12 Amps at 115 Volts, making it suitable for use in most applications. It has a single, universal mounting system and is suitable for use on most panels or surface-mount installation. In addition, the WR13AL/CUL also meets a wide range of electrical standards, including UL, CSA, IEC, and EN/IEC.

Application Field

Rocker switches are most commonly used for controlling simple everyday circuits like those found in homes, offices, and factories. The WR13AL/CUL rocker switch is particularly useful in applications that require the switch to be positioned instead of actuated, such as on a light switch panel. This makes it an ideal choice for controlling lighting, HVAC systems, motors and other simple circuits, as well as for managing alarm and security systems.

In addition, the WR13AL/CUL rocker switch is also popular in medical and industrial applications. Hospitals and medical facilities, in particular, often choose a rocker switch over other types of switches, as they offer easy to use, reliable control of many circuits. And in industrial settings, rocker switches are often used to control large machines or components, as they allow the operator to adjust the circuit without the need for specialized tools.

Working Principle

Rocker switches are simple on/off switches that control an electrical circuit. To operate, they require a toggle switch or rocker switch. This switch is typically mounted on the circuit board, and is connected to a spring-loaded contact. When the rocker switch is pushed or toggled, it activates the contact, which completes the circuit and sends the current to the connected device.

The beauty of rocker switches is that they require minimal force to operate. The contacts move freely and don’t need to be pressed in order to complete the circuit. This allows them to be used in tight spaces, and they are often the go-to choice in high-traffic and complex configurations. As such, they are ideal for use in applications where multiple circuits need to be controlled quickly and reliably.

Conclusion

The WR13AL/CUL is an affordable, robust and versatile switch that is well-suited for a wide range of applications. Its one-piece construction and two-state switching action make it ideal for controlling lighting, HVAC systems and alarms, as well as for use in medical and industrial applications. Furthermore, its easy to operate toggle switch makes it the perfect choice for situations where multiple circuits need to be managed quickly and reliably.
