Snap Action, Limit Switches, V7-7B17D8-201 application field and working principleSnap action limit switches are some of the most important components in automation technology. They are used in numerous applications, from industry automation to medical equipment. The V7-7B17D8-201 is a high-performance limit switch designed for use in those applications.A limit switch is an electromechanical device that is used to detect the presence or absence of an object. It consists of an actuating lever, a contact system, and a mechanical or electronic switching mechanism. When the lever is activated by an object, the contact closes and the switch activates. Limit switches are used to control a variety of mechanical functions, such as operating valves, starting and stopping motors, limiting travel of an arm, and others. The V7-7B17D8-201 is a double pole, double throw (DPDT) snap action limit switch. It has a four-pole momentary contact mechanism, meaning it has four separate contacts that can be switched on and off when the lever is activated. This makes the switch suitable for a wide range of applications.The V7-7B17D8-201 is designed for rugged industrial environments, offering superior reliability and long-term durability. It is UL-approved and CSA-certified for both indoor and outdoor use. It has a built-in manual override and a self-cleaning contact system, which eliminates dust accumulation and helps to maintain stable electrical contact and consistent performance over time. The switch also features a dust- and water-tight housing and a temperature range of -25°C to +80°C (-13°F to +176°F). The V7-7B17D8-201 works on the following principle: when an object activates the lever, it causes a rotary cam, located inside the switch, to shift position. This shifts a set of electrical contacts, allowing current to flow and activate the switch, which then sets off the mechanical operation.( e.g. opening or closing a valve). When the object is removed, spring force returns the cam to its original position, returning the contacts to their initial state and deactivating the switch.The V7-7B17D8-201 is suitable for a wide range of industrial and consumer applications, including machine automation, door and window opening systems, fluid level controls, waste water monitoring systems, medical instruments, and more. It can be used to control a variety of equipment, from simple motors to complex automation systems. Its rugged design and reliable performance make it an ideal choice for many industrial and consumer applications.In conclusion, the V7-7B17D8-201 is a high-performance snap action limit switch that is designed for use in tough industrial environments. It features a four-pole momentary contact mechanism, a dust- and water-tight housing, and a temperature range of -25°C to +80°C (-13°F to +176°F). It is suitable for a wide range of applications, from machine automation to medical instruments.
