As an industrial-grade electrical switching device, YIJIA Relay with Lockable Test Button adds a manual test button and a locking structure on the basis of the core functions of a standard relay. It can be manually triggered for detection during installation, maintenance or troubleshooting without additional control signals, quickly verifying the operation status of the equipment. Its shell is made of engineering plastic, and the contacts are equipped with silver alloy materials, which have high conductivity and arc resistance, enabling stable operation under complex working conditions. At the same time, it has a built-in high-brightness LED status indicator to display the working status of the relay in real time, suitable for applications in industrial automation, safety systems, power distribution and other fields.
Core Functions & Design Highlights
YIJIA Relay with Lockable Test Button is equipped with a lockable test button, supporting toggle between manual test and locking mode. During testing, no external signal is required, which facilitates quick completion of equipment power-on and action verification, improving installation and maintenance efficiency. The locking function can prevent accidental pressing or activation by unauthorized personnel, avoiding equipment failures or safety risks caused by unintended operations, especially suitable for safety-critical systems to enhance operational safety.
The product contacts are made of lead-free and cadmium-free silver alloy, which balances high conductivity and arc resistance. Logic-level signal transmission is smooth, and it can stably connect and break under full-load working conditions. The shell is made of flame-retardant engineering plastic, complying with industrial safety standards, and is matched with irradiated high-temperature wires, which are halogen-free, low-smoke and low-toxic, suitable for long-term use in industrial environments. The power frequency withstand voltage between the coil and the contacts is above AC2200V, with excellent insulation performance, reducing the risk of leakage and short circuit.
It integrates a high-brightness LED indicator, which clearly distinguishes the pull-in and release status of the relay, facilitating on-site personnel to quickly identify the operation status. The inside of the socket adopts an integral connection structure, reducing assembly errors and improving the overall reliability of the equipment. Multiple contact specifications are available, supporting 2 groups, 3 groups and 4 groups of convertible contacts, adapting to different load and control needs. The rail mounting method is suitable for various control cabinets and distribution boxes, with convenient installation and space saving.

Frequently Asked Questions (FAQ)
1. How to use the lockable test button?
First press the test button to trigger the relay action and verify the contact switching and indicator status. After the test is completed, fix the button position through the locking structure to prevent accidental pressing, and it can return to normal use after unlocking.
2. Which voltages and loads is the product compatible with?
The rated operating voltage is DC24V (common specification), suitable for resistive or inductive loads of AC250V/28VDC and maximum 15A. Specific models can be selected according to contact specifications and actual working conditions.
3. How to judge the working status of the relay?
The built-in LED indicator turns on and off synchronously with the pull-in/release of the relay, which can intuitively identify the working status. If the indicator is abnormal, the contact or coil fault can be quickly checked through the test button.
4. What is the environmental adaptability of the product?
The operating temperature ranges from -40℃ to +85℃, withstanding 45%–85% relative humidity. It also has vibration resistance and impact resistance, suitable for complex environments such as industrial sites and outdoor power distribution.
5. Does the product provide customized services?
