LSYFB4L

The LSYFB4L snap action limit switch is a commonly used switch for many commercial and industrial applications. It is a two-position normally open switch that is opened and closed manually by pressing a button or lever. The switch can be used in a variety of applications, from controlling lamps and other small loads in commercial applications to more complex industrial control applications. This article will provide an overview of the LSYFB4L snap action limit switch, its application field, and its working principle.

Application Field

The LSYFB4L is capable of switching up to 10A of AC or 7A of DC at 24V and comes in several contact forms, including: simple switching, with a single input and output contact; double switching, with two inputs and two outputs contacts; and latching/delay switching, with two inputs and two outputs contacts plus a timer. This versatility makes the LSYFB4L suitable for a variety of applications. For example, it can be used in commercial applications such as controlling the light system in an office building or hotel. It can also be used in industrial applications such as controlling motors, pumps, or fans. Furthermore, its latching/delay functionalities provide interesting possibilities in equipment that require delayed shutdowns.

Working Principle

The LSYFB4L snap action limit switch is a two-position normally open switch that is actuated manually by pressing a button or lever. It uses a simple mechanical mechanism to move the switch from its normally open position to its closed position. The mechanism of the switch consists of a base, a plunger, and a contact assembly. When the plunger is pushed in, it pushes the contact assembly against the adjacent surface, creating a connection between the two contacts and activating the switch. When the plunger is released, the contact assembly springs back to its normally open position.

The LSYFB4L limit switch is also equipped with a durably constructed spring-loaded safety lock that locks the switch in its closed position until released. This safety lock not only prevents accidental opening of the switch but also provides an extra measure of safety in the event that the switch fails to open. Furthermore, the LSYFB4L limit switch is designed to support lightning surge withstand of up to 10KV, making it suitable for applications with harsh environmental conditions.

The LSYFB4L snap action limit switch is a versatile switch that is suitable for many commercial and industrial applications. Its two-position normally open structure, mechanical simplicity, spring-loaded safety lock, and lightning surge withstand make it a reliable and cost-effective solution for lighting control, motor/pump/fan control, and other applications.
