Toggle switches are electrical switches that control the flow of electrical currents in a circuit, and they are easy to operate with a simple lever mechanism. The 1TL133-21 toggle switch is a popular toggle switch with a variety of applications and a simple yet reliable working principle.

The 1TL133-21 is a single-pole double-throw (SPDT) toggle switch suitable for applications where one or two switched circuits are connected in a parallel arrangement and may be closed, opened, or dependent on one another to be powered. For example, the switch is suitable for high voltage and low voltage lighting fixtures and appliance control situations, providing switching between two different circuits at once. The current rating for this toggle switch is 6A/250V AC (NO-OFF rating), and the contact resistance is less than 30mΩ.

The 1TL133-21 can also be used in safety applications, such as controlling a high voltage isolation transformer. The switch has a low voltage rating and a high voltage rating and a current rating of AC 6A/250V in order to ensure complete circuit isolation. This makes it an ideal choice for emergency lighting, emergency lighting systems and other safety-critical applications.

The 1TL133-21 switch has a simple yet reliable mechanism. When the toggle switch is turned on, one of the two contacts is connected to the common terminal, and the other contact is connected to the normally open (NO) terminal. When the switch is turned off, both contacts are disconnected from the common terminal, and the normally open contact is connected to the normally closed (NC) terminal. The switch also has a built-in overload and short circuit protection, meaning that if too much current passes through the switch it will automatically shut off. This ensures that the switch is safe for use in both residential and commercial applications.

In summary, the 1TL133-21 toggle switch is a popular switch suitable for many applications, with a high voltage and low voltage rating, a current rating of 6A/250V AC and built-in overload and short-circuit protection. The switch is easy to operate and has a reliable operating mechanism, making it an ideal choice for a wide range of applications.
