Rocker switches are common in many areas of electronic engineering and offer critical protection to devices from unexpected electrical power surges, particularly in sensitive medical, automotive, and industrial applications. The SRL91-22ARN3-BB9N is a popular rocker switch that has a proven track record of high reliability and long life in a variety of situations. This article will examine the application field and working principle of the SRL91-22ARN3-BB9N rocker switch.

The SRL91-22ARN3-BB9N is a single-pole, double-throw switch, meaning it can simultaneously control two separate circuits. It features a black or brown (depending on the model) plastic body, screw termination, and an actuator that is labeled "ON/OFF". It is rated for up to 6A at 120VAC in OFF-ON circuits, and up to a 1/3HP at 250VAC in ON-OFF circuits. The switch is UL and CSA recognized and is suitable for up to 50,000 mechanical operations, making it ideal for use in critical applications where reliability and long service life are required.

The SRL91-22ARN3-BB9N is commonly used in medical equipment, such as patient monitors, medical beds, surgical equipment, and infusion pumps. It is also commonly found in automotive electronics, such as speedometers, tachometers, and headlamps. It can also be used in industrial applications, such as controlling and automating factory equipment, and for powering and controlling LED systems in buildings and security systems.

The SRL91-22ARN3-BB9N is a form of electromechanical switch. Its basic function is to start and stop electrical power in particular circuits. As the actuator of the switch is toggled (either through twisting or a toggle-style mechanism), it either connects or disconnects the two contacts of the switch. Depending on the model, the switch will be wired with the common lead to either the top or bottom contact, making it a single-pole, double-throw (SPDT) switch.

The SRL91-22ARN3-BB9N is an extremely reliable switch due to its heavy-duty screw terminations, solid construction, and long expected service life. Its quick and accurate switching makes it ideal for many critical and sensitive applications, such as medical and automotive equipment.

In summary, the SRL91-22ARN3-BB9N rocker switch is a heavy-duty, single-pole, double-throw switch that is suitable for a variety of applications, from medical equipment to automotive electronics. Its quick and accurate switching, heavy-duty screw terminations, and long expected service life make it an ideal choice for reliable and long-term use.
