Toggle switches serve an invaluable role in the circuitry and operation of multiple devices both large and small. One of the most well-known models is the TL2220-7, a versatile switch with variety of configurations and usages. This article will provide an overview of the TL2220-7\'s application field and working principle.

The TL2220-7 is a mini toggle switch utilizing a momentary toggle action. It features DPDT (double-pole-double-throw) contacts built for on-off or two-way switch functions. The voltage rating for the switch is 125VAC and the current rating stands at 2A, making it suitable for a majority of residential and commercial wiring scenarios. In terms of wiring, the switch is equipped with two 0.187 spade terminals. The overall dimension of the device is 0.563’’ x 0.25’’ x 0.625’’ (LxWxH).

The TL2220-7 is ideal to use in a broad range of situations. For instance, it can be deployed in electrical measuring instruments as well as easy-to-access devices like household lighting fixtures and vending machines. Instrumentation aside, the switch can be linked up to office machinery, door locks, signal systems, automobile components and HVAC systems too.

In terms of functioning, the TL2220-7 works with simple mechanics. Toggle switches leverage either a rocker arm or a lever that’s linked to a spring inside the switch, although the TL2220-7 operates with a momentary toggle. When manually pushed or pulled, the spring shifts the toggle up or down to activate one of two pre-built contact points. This change in position is usually made clear to the user by the switch indicating a steady “on” or “off” state. This can offer plenty of control options, especially if the switch is single-pole, double-throw as opposed to a double-pole, double-throw type.

The plastic construction of the switch is also an important feature to consider. Most versions of toggle switch construction are actually made of light weight plastic instead of nickel or steel for a few reasons. First, plastic switches are typically a much safer choice due to thelower levels of electrical conduction. Plastics transmit electricity better than the aforementioned materials, which reduces the chances of short-circuiting or danger during usage. Second, plastic enables the switch to be much more wear and tear resistant, making it a reliable component for use in a wide range of environments.

The TL2220-7 is exclusively a momentary action switch, however. This means that when the toggle arm is pressing the contact point, the contacts should be closed in order to stay on. This can be a major drawback the more control a user desires, as another option is to use a latching toggle switch. With those switches, each toggle position corresponds with a locked position on the switch, with no need to continually reapply pressure.

Overall, the TL2220-7 is a versatile switch that is suitable for a wide variety of usage scenarios. The momentary action enables an easy switch between positions when applied, while the lightweight plastic construction ensures a durable, safe construction. Though there are a few drawbacks that may match up with the needs of some users, the TL2220-7 is a reliable toggle switch for a diverse range of applications.
