LW3123/CUL-L4CF-A application field and working principle

Rocker switches are so common that it is almost a “default” design used in many applications. The LW3123/CUL-L4CF-A application field and working principles are no exception. It is a single-pole double-throw (SPDT) type that is used to control three positions from a common terminal. It works with 120 VAC operations, having a power rating of 6A/125V AC. It also has a maximum switch life of 200,000 cycles.

This unit comes with a rocker actuator with a 4-position lever that can be turned in a clockwise (longitudinal) switching operation. It provides a common-pole contact configuration and has a maximum contact resistance of 50MΩ max. It is also designed to be dust-proof, oil-safe and dust-ignition proof, so it can be used in environments such as military, marine and industrial applications. This unit is rated IP67, making it impervious to ingress of dust and water, with a temperature range of -25 to +85 degrees celsius.

The working principle of the LW3123/CUL-L4CF-A is simple. The rocker switch is wired into a circuit, with the actuator being turned in the clockwise direction closing and opening the contacts. When the actuator is turned, the three contacts are either opened or closed. When the actuator is in its neutral position, the three contacts open, breaking the electrical connection.

In terms of applications, the LW3123/CUL-L4CF-A can be used in a number of different applications. Common uses include appliances, such as in an oven, stove or washing machine to control the power, or in a vending machine to control a vending cycle. The LW3123/CUL-L4CF-A is also used in industrial control applications, to control a conveyor belt, for example. It is also often used on military and aerospace electronics, as well as in medical equipment.

The LW3123/CUL-L4CF-A rocker switches offer many advantages over other switch designs. They are relatively low cost, easily adjustable, durable and suitable for multiple applications. Its IP67 rating makes it highly resistant to water, dust, oil and other chemicals and extreme temperatures. As such, this type of switch is often seen in many of the most demanding applications.
