Pushbutton switches are devices that are used to control or initiate a specific action in an automated system. They are also known as momentary contact switches, or self-locking switches. SA1RV20 is one of the most popular pushbutton switches in the market. This paper will discuss the application field and working principle of SA1RV20 pushbutton switch.

SA1RV20 pushbutton switch is a self-locking switch that is commonly used for commercial and industrial applications. The rated current and voltage of the switch are 250V, 2A AC (120V, 15A AC), and 240V AC (108V, 10A AC). The switch is designed to withstand a wide range of environmental conditions, including dust, shocks, humidity, and vibrations. It is UL approved and meets the requirements of ENEC10/ENEC11, and is suitable for safety-related applications.

The SA1RV20 pushbutton switch has two different types of contact constructions, including a normally closed (NC) type and a normally open (NO) type. The NC type is used when the contact should be closed when the pushbutton switch is in the rest or in the “off” position. The NO type is used when the contact should be open when the pushbutton switch is in the rest or in the “off” position. The switching action of the switch is accomplished by pressing the button, which moves a plunger in and out of the switch body. When the button is pressed, the plunger presses against the contact surface and allows current to flow. When the button is released, the current flow is stopped as the plunger returns to its original position.

SA1RV20 pushbutton switch is typically used in industrial control systems, such as manufacturing, process control, and machine automation. It can be used to start and stop motors, machines, pumps, conveyors, and other equipment. It is also commonly used in alarm systems, safety systems, signaling systems, and electrical equipment panels. The switch is also used for controlling access to secured areas, as well as for controlling lighting and ventilation systems. The switch is a cost-effective solution for many applications, including manual or automated operation.

In conclusion, the SA1RV20 pushbutton switch is a popular and reliable switch for commercial and industrial applications. The switch is offered in two different contact constructions, NC and NO, and has a wide range of rated currents and voltages. The switch is designed to withstand a variety of environmental conditions, and is UL approved and ENEC10/ENEC11 compliant. The switch is typically used in industrial control systems, and can be used to start and stop motors, machines, pumps, conveyors, and other equipment. It is also used in alarm systems, safety systems, signaling systems, and electrical equipment panels.
