V3L-3

Snap action limit switches are popular choices in industrial applications. These devices are designed to detect and measure movement, temperature and pressure. The V3L-3 is a versatile and economical choice when it comes to snap action limit switches.

Application Field

V3L snap action limit switches are mainly used in the automotive and HVAC (heating, ventilating and air-conditioning) industries. They are also used in medical and industrial automation, consumer durables, industrial machinery and equipment, and many other applications. These switches are also suitable for both control and sensing circuits.

The switches have a wide range of application including door and window open and close detection and control, vibration-resistant environment for operating machines and equipment, temperature control of temperature and pressure ranges, mechanical feedback control, and a range of product safety requirements.

Working Principle

The V3L snap action limit switches use a plunger lead to actuate the switch. The plunger moves when pressure is applied to the switch contact’s base, causing the contact to open or close. The amount of movement is determined by the amount of force applied to the plunger. When the switch is released, the plunger returns to its original position, resulting in the switch opening or closing. This type of limit switch can be classified into three types: normally open, normally closed, and combination.

When choosing an application for a snap action limit switch, it is important to consider the type of switch that best fits the application and the environment. The factors to consider include the frequency of actuation, range of movement, voltage and current, temperature and pressure range, resistance to vibration and corrosive atmospheres, and the ability to withstand shock and vibration.
