Toggle Switches

Toggle Switches, also known as lever switches, are often used as on/off switches for devices like lights, computers, appliances, and other electronic controls. To provide user convenience, these switches feature a compact size, low profile, and either a standard or special operating lever arm.

One of the most popular toggle switches is the 7201D - a double pole double throw switch. This type of toggle switch features excellent contact performance and reliable switching action. Generally, it has a panel-mount base with a pre-drilled hole designed to easily fit into various circuit boards achieved with precision casting mold.

7201D Application Field and Working Principle

The 7201D toggle switch is an ideal component for controlling one, two, or a few circuits. It can be found in a wide range of applications such as for security systems, household appliances, computer networks, and voice equipment. Additionally, one of the main uses of this switch is for switching between two power sources, such as a battery charger and the main power supply.

This switch has two metal contacts, called “poles”, which are connected to two metal blades or contacts that are also connected down to a switch actuator or lever. The metal contact positions operate independently and can be set to give either a closed or open connection. The lever is spring loaded and can be operated by pressing the switch either on or off and then releasing it back to the original position. When the switch is in the on or closed position, electricity will flow from the metal contacts and down the metal blades to the switch actuator and then on to the load. When the switch is in the off or open position, no electricity will flow.

Conclusion

The 7201D toggle switch is an easy to use and reliable component that can be used to control one, two, or a few circuits. Thanks to its pre-drilled holes, it is a great option for DIYers and those who are looking for a high-quality switch that can fit into their circuit boards with precision. Additionally, it offers excellent contact performance and reliable switching action for long-term use.
