Rotary Switches

Rotary switches are electromechanical devices used to control electricity in different electrical circuits. They are identified by the number of positions in which the switch is capable of being placed and the number of poles (lines of electricity) that are connected when a given switch is connected. The PLR3279 is a popular example of a rotary switch.

PLR3279 Application Field and Working Principle

The PLR3279 is primarily used in applications such as industrial automation, lighting control, security and access control systems. It can be used in any application that requires the control of multiple circuits with a single switch. The switch is suitable for low power circuits (18A at 250 Vac) and includes multiple poles and positions.

The switch is made from a plastic body with a rotating knob. The knob is connected to the mechanism that moves the contacts between the various positions. These contacts create a circuit between the lines of electricity and the switch when the knob is rotated. Since the knob is turned, the contacts can be placed in any one of the positions at the same time. This offers great flexibility when connecting circuits.

The switch has a two-point suspension system, which allows the contacts to align with the desired position of the switch. This allows the switch to work smoothly and consistently. The contacts are also sealed with a silicone sealant, so they are protected from moisture and corrosion. The switch also features a dust-resistant coating, so it can withstand most environment conditions and corrosion.

The switch operates either as a single-pole switch or a multi-pole switch, depending on the number of positions available. The switch is rated for 250V and is able to handle 18A. This ensures the switch is suitable for most applications. The switch must be connected to a circuit board or the necessary wiring must be installed to make it work. The switch is easy to install and requires no additional tools for installation.

The PLR3279 rotary switch offers great flexibility and superior performance in applications where multiple circuits need to be controlled. The switch is rated for 250V and can handle 18A, making it suitable for most applications. The switch has a two-point suspension system, which allows the contacts to align perfectly with the desired position. The contacts are also sealed with a silicone sealant, which protects them from moisture and corrosion. The switch also features a dust-resistant coating, so it can withstand most environment conditions and corrosion. The switch is also easy to install and requires no additional tools for installation. It is an ideal switch for applications in industrial automation, lighting control, security and access control systems.
