Rocker Switches

Rocker switches are an ideal solution for any circuit switching requirement, especially when the switch needs to be mounted to a wall or panel. The ST21L4S4CQEJ22 model is a popular choice for this application, and it can be found in many commercial, industrial and residential systems.

Application Field and Working Principle

The ST21L4S4CQEJ22 rocker switch is designed for AC current control, and it can be used on both AC and DC circuits. This switch is suitable for uses in residential and industrial units and is commonly used in circuit breaker panels, power control systems and load centers. The switch has excellent electrical isolation, making it suitable for use in high voltage applications up to 660 volts.

The ST21L4S4CQEJ22 rocker switch uses a rotary mechanism that operates between two springs. It is powered by a single-phase, AC power supply and is actuated by either a push button or twist action. As the switch is activated, it moves from one spring to the other in a rocking motion, breaking or making contact to the current supply.

The ST21L4S4CQEJ22 is protected from dust, moisture and external interference by a cover plate and a dust cover. These features give the switch superior electromagnetic compatibility, making it suitable for installations in commercial and industrial units with electrical noise, such as factories, machine shops or HVAC systems. The switch is designed for a long lifespan and withstands high temperatures, making it the perfect choice for any application.

Installation and Maintenance

The ST21L4S4CQEJ22 rocker switch is easy to install and requires no special tools or modifications. The switch can be mounted on a wall or panel with a few screws, and it requires only a standard junction box. If a special junction box is required, the switch has provisions for this and it can be mounted on either a vertical or horizontal surface.

Maintenance on a ST21L4S4CQEJ22 rocker switch is minimal, but it should be regularly inspected to ensure proper operation. To ensure safety, the junction box and the switch itself should be regularly inspected for loose wires or dirt buildup. If a problem arises, the user should refer to the manufacturer\'s instructions as it may be necessary to use an anti-static or anti-shock tool to service the switch.

The ST21L4S4CQEJ22 rocker switch is a reliable, efficient and cost-effective solution for any circuit switching requirement. It is a versatile and easy to install switch that is compatible with a wide range of power supplies, making it suitable for numerous applications.
