Toggle switches are an essential element of a number of electronic applications. Their robust construction and various options for mounting make them an excellent choice for controlling circuits. The M2021BB3W01 toggle switch is a single pole, single throw (SPST) toggle switch, with two positions. It is designed to provide reliable and economical lateral switching between two circuit branches.

Mounting Options and Dimensions

The M2021BB3W01 switch features two different mounting options. The first, a bracket mount, is designed to be installed into a panel, or onto equipment which uses hole patterns. The second type of mount, a bushing mount, is designed to be fitted onto a panel, or into a bushing, depending on the specific application. The bracket mount provides an easy means for mounting and fixing the switch to the panel. Both types of mounting options are available in different panel thicknesses to accommodate various applications. The M2021BB3W01 switch has a panel cut out size of 35.3mm x 16.5mm and the bushing mount has a 12.7mm diameter for convenience.

Working Principle

The M2021BB3W01 toggle switch is a single pole, single throw (SPST) switch. It can easily switch between two positions, with the switch arm being mechanically linked to the internal contacts. The switch is designed to provide reliable and economical switching between two branches of a circuit, with low power draw and high contact reliability. In its OFF position, the switch breaks the circuit, thereby cutting power off. In its ON position, the switch completes the circuit and allows power to flow.

Applications

The M2021BB3W01 toggle switch has a wide range of applications. Its low power draw and size makes it suitable for use in general control applications such as lighting and fan control. The switch can also be used in automotive, marine and recreational vehicles, allowing for switches to control lights, fans, pumps and more. In industrial settings, the toggle switch can be used for heavy-duty applications such as cranes, hoists and other production equipment.

Conclusion

The small size and robust construction of the M2021BB3W01 toggle switch make it an excellent choice for a variety of applications. It switches reliably between two positions, and can also be used in applications where a low power draw is required. It is available in two convenient mounting options and its small size makes it easy to install into panels or upon equipment.
