Rocker Switches

Rocker switches are specialized switches offering three positions: ON, OFF and often a “midspan” position between the ON and OFF. The OFF position is important, as it prevents inadvertent operation. This switch is often used in industrial and home automation applications, with the addition of a pilot light or LED in order to indicate the current switch position.The B121J21ZQ22M is a 30Amp Double Pole Rocker Switch of 600VAC/125VDC that is perfect for industrial and home automation applications. With its robust construction and quality silver-plated contacts, it offers reliable operation in both commercial and residential applications. The switch is available in a variety of colors, with the choice of a bezel for mounting or a snap-in mount option.The basic operation of the B121J21ZQ22M is to use its “ON” position to turn the circuit on and its “OFF” position to turn the circuit off. A pilot light or LED is recommended to indicate the current switch state. In addition, many of the B121J21ZQ22M models include an intermediate “midspan” position. This position provides a middle point between the “ON” and “OFF” states, and is often used for controlling multiple circuits that must remain isolated from each other for safety.The B121J21ZQ22M uses an internal mechanism to control the switch state. The mechanism typically operates using a cam and lever. The cam rotates to move the lever and change the switch state. The internal mechanism also includes a spring-loaded mechanism to hold the switch in its current position, even when subjected to vibration or shock.When it comes to the physical dimensions of the B121J21ZQ22M, the bezel measures 2.3 inches across and measures 1.2 inches high. It is approved to UL 508 specifications and is CSA certified. The snap-in mount option adds an additional 0.8 inches in width. In terms of installation, the switches can be wired to the source line prior to or after installation.The B121J21ZQ22M represents an excellent choice for reliable and durable rocker switch operation. Its variety of switch states, robust construction, and quality silver-plated contacts make it suitable for any application requiring multiple switch positions and durable contacts. Additionally, the variety of mounting options, along with its small size and UL/CSA certification, ensures that it can be used in a variety of applications.
