Toggle Switches

WT123S1YZG Application Field and Working Principle

Toggle switches are utilised in an extensive array of applications ranging from the mundane to the critical. The WT123S1YZG toggle switch, in particular, is a high-performance device serving a variety of commercial, industrial and military settings, thanks to its superior durability and ruggedness.

The WT123S1YZG toggle switch is a three-position, spindle-operated toggle switch. It is Class I Div 2 certified and is rated for 10A at 250 VAC or 14V DC with contact resistance of 100mΩ. Apart from its superior electrical characteristics, it also offers simple installation, thanks to its reversible mounting system, and a wide range of termination options.

The WT123S1YZG toggle switch is also distinguished from its competitors by its robust construction. It has no exposed screws and is IP67 rated for both indoor and outdoor settings. It is also certified for a wide range of hazardous environments. The housing is corrosion-resistant and constructed from die-cast zinc. The spindle is 7/16-28 UNF thread with 5/16-32 UNF spindle cap, and can be rotated 270° with a self-locking design.

The WT123S1YZG toggle switch is typically used in remote operated switching. It is a preferred choice for applications such as lights, pumps, air handlers, water heaters, and other ignition applications.

The working principle for the WT123S1YZG toggle switch is straightforward. When the button is pressed down and the handle is moved to either the left or right side, it changes the connection of the spindle. This changes the direction of current flow and in turn, activates or deactivates the associated device.

Toggle switches such as the WT123S1YZG are typically used when a low-current device needs to be operated. Since it offers extreme durability and reliability, it is a preferred choice for many hazardous and remote operations. With the advent of reliable and user-friendly electronics, toggle switches are becoming less commonplace. However, their reliability and long-lasting performance has allowed them to remain relevant in certain applications.
