1. Precision Engineering and Customization
Yijia’s metal push button switch factory produces switches in precise sizes: 12MM, 16MM, 19MM, 22MM, 25MM, and 30MM, ensuring compatibility with diverse industrial panels. For example:
High-round cap momentary metal push button switch: The YJ-GQ22BH model offers tactile feedback, IP67 protection, and supports 3V/6V/12V/24V/36V/48V/110V/220V LED lighting for low-power IoT devices or high-voltage systems.
Flat round metal push button switch: The YJ-GQ22BF features a sleek design with laser-etched symbols, ideal for elevator controls or smart home interfaces.

2. Momentary and Latching Functionality
Momentary metal push button switch: The YJ-GQ16BF activates circuits temporarily, designed for automotive dashboards with gold-plated contacts (≤50mΩ resistance) and 16MM mounting.
Latching metal push button switch: The YJ-GQ22BF maintains state until reset, featuring a 22MM stainless steel body and IP67 protection for marine equipment.
3. Waterproof and LED Integration
Yijia’s waterproof industrial push button switch models, such as the YJ-GQ22BF, withstand extreme temperatures (-35°C to +75°C) and harsh environments like chemical plants. Their IP67 waterproof button switch designs use epoxy-sealed terminals and NBR70 gaskets to prevent dust and moisture ingress.
LED-lighted push button metal on-off switches enhance usability in low-light conditions. For example, the YJ-GQ19B integrates blue backlighting with ring illumination, while the YJ-GQ16 offers red LED indicators for emergency stops.
4. Applications Across Industries
Industrial Automation: The stainless steel push button switch (YJ-GQ19B) ensures reliability in CNC machines with 200,000+ mechanical cycles.
Transportation: Vibration-resistant switches like the YJ-GQ16R are used in automotive controls, supporting 12V/24V systems.
Smart Systems: Compact 12MM–30MM designs integrate into appliances, offering energy-efficient lighting and tactile feedback.
Yijia Industrial Control Electric Co., Ltd. stands at the forefront of China metal push button switch manufacturers, delivering customizable, waterproof solutions with stainless steel durability and multi-voltage LED versatility. From momentary to latching designs, YJ-GQ series caters to global industries requiring precision and resilience in harsh environments.
