Littelfuse Corporation (NASDAQ: LFUS), a leading enterprise providing diversified and advanced solutions for safe and efficient power transmission, 

announced today the launch of the Littelfuse/C&K® TSC series of toggle switch safety covers. These covers are designed to prevent accidental triggering 

of toggle switches in critical control systems.

The accidental triggering of switches can lead to unexpected operation of equipment, pose safety risks, and result in costly downtime. The TSC series 

addresses these challenges through a precise spring-loaded mechanism that physically protects the toggle switch while enabling intentional one-handed 

operation.

The safety covers are specifically designed for demanding environments and combine a robust structure with a clean and professional appearance, suitable

 for modern control panels.

The TSC series features a sturdy high-gloss black stainless steel panel, with ABS covers available in various colors for clear and intuitive identification of key 

functions. This design offers a simple no-repanel upgrade solution and is compatible with standard 12.0 mm (15/32 inches) mounting holes, with switch 

lever heights up to 25 mm, suitable for various existing toggle switch designs.

"The development of the TSC series was aimed at addressing a common but often overlooked risk in control system design - accidental switch triggering," 

said Jesus Santos, Global Product Manager of Littelfuse. "By combining a reliable spring-loaded mechanism with durable materials and intuitive operation, 

these safety covers can help engineers enhance system safety without increasing design complexity."

Key features and benefits:

· Prevent accidental triggering: Spring-loaded protective covers effectively reduce the risk of misoperation

· Simple and intuitive operation: Easy to open and close with one hand, convenient to use

· Robust structure: Stainless steel panel and durable ABS cover provide long-term reliability

· Visual identification: Multiple color options support clear marking of key functions

· Ready-to-install upgrade: Compatible with standard panel openings (12.0 mm / 15/32"), facilitating retrofitting

· Designed for harsh environments: Suitable for demanding industrial, transportation, and outdoor applications

The TSC series toggle switch safety covers are ideal for applications requiring high safety, reliability, and clear operation, including industrial control 

equipment, commercial vehicles and off-road vehicles, ship systems, aerospace platforms, and high-reliability equipment. In these fields, preventing 

accidental triggering is crucial for maintaining safe and reliable operation.

The TSC series combines mechanical protection with ease of use and design flexibility, providing engineers with a practical solution to enhance the safety 

of control systems without the need to redesign existing hardware.

Common questions about the TSC series toggle switch safety covers:

1. What problems can the TSC series safety covers solve?

The safety covers prevent accidental triggering of toggle switches, thereby avoiding equipment damage, safety risks, and system downtime. Spring-loaded

 covers ensure that switches can only be triggered with intentional operation.

2. How easy is the operation of the safety covers?

The design of the safety covers makes it easy to open and close with one hand, allowing for quick operation of the switches while still preventing 

accidental triggering.

3. Are these covers compatible with existing toggle switches?

Yes. Its design is suitable for standard 12.0 mm (15/32") mounting holes and can support a switch lever up to 25 mm, applicable to many existing designs.

4. For which environments are the TSC series suitable?

They are specifically designed for harsh and demanding environments, including industrial systems, transportation, ships, aerospace, and high-reliability 

applications.

5. Does the cover support visual recognition of the switch?

Yes. A variety of colors are available, enabling engineers to clearly distinguish key functions and enhancing the awareness of operators.

6. What materials are used in the TSC series?

The safety cover is made of a durable ABS shell and stainless steel panel, which not only has mechanical strength but also long-term reliability.
