Rocker Switches

RB242D1021-116 has become a go-to switch for a wide range of applications on commercial and industrial circuits. A basic understanding of its design and function can be valuable to the educated technician or installer. Rocker switches are found in a range of applications from the automotive industry to household appliances and the entertainment industry. This article describes the different elements involved in the design and operation of this specific switch and how it is used in commercial and industrial applications.

Design and Function

RB242D1021-116 is a two-position, two-circuit, panel-mount rocker switch. It has two contact terminals, a common terminal, and a switching mechanism mounted onto a body panel. An internally-mounted rivet and spring mechanism allows actuation of the contact terminals when the switch is moved from one position to the other. This type of switch is designed to be mounted in a panel cutout, with its actuator protruding through the panel surface.

Performance-wise, this switch is rated for 10A at 125VAC. This makes it suitable for a wide range of applications, from household appliances to commercial and industrial uses. It is commonly used for power and lighting control, signal measurement, and thermocouple applications.

Installation

This rocker switch can be installed into a cutout on a control panel or chassis. The body panel of the switch is attached to the back of the panel or chassis. The wires are then soldered to the two contact terminals. The common terminal is then soldered to the chassis or control panel. Finally, the actuator of the switch is secured with a mounting nut and the panel is closed.

Maintenance

Rocker switches tend to require minimal maintenance in applications with clean, dry environments. If the switch is used in an environment that is prone to dust, dirt, or moisture, then periodic cleaning and lubrication may be necessary. In these cases, contact resistance should be regularly monitored, and the switch should be replaced if it starts to malfunction.

Conclusion

RB242D1021-116 is a two-position, two-circuit, panel-mount rocker switch that is widely used in commercial and industrial applications. Its design ensures reliable performance in a range of applications, from power and lighting control to signal measurement and thermocouple applications. With proper installation and maintenance, this switch can be expected to provide years of reliable operation.
