Plastic push button switches are essential components in electrical control systems. YIJIA specializes in manufacturing these switches using high-performance materials such as polycarbonate (PC) and polyamide (PA). Plastic push buttons are used to control power on and off by pressing or pushing. They operate in either momentary or latching modes. Understanding the difference ensures optimal performance in a wide range of applications, from industrial machinery to consumer electronics.
Operating Principle:
Activates only when pressed. Returns to default state immediately upon release.
Key Features:
Momentary Control: Suitable for short-term operation (e.g., doorbell, reset function).
Spring Mechanism: Built-in spring ensures automatic reset.
Voltage Compatibility: Supports 3V to 380V LED lighting (optional: red/green/blue/yellow/white).
Typical Applications:
Emergency stop for medical equipment
Keypad keys
Test and measurement equipment
Operating Principle:
Once activated, maintains its state until pressed again. A "push-and-push" mechanism locks the circuit.
Key Features:
Stable state retention: No need to continuously press; energy-efficient.
Bistable design: Each press switches the switch between on and off.
Material durability: The PBT/POM housing ensures over 100,000 mechanical cycles.
Typical Applications:
Power switches for heating, ventilation, and air conditioning (HVAC) systems
Start/stop controls for industrial machinery
Lighting systems in public infrastructure

Q1: What is the difference between momentary and latching switches in circuit design?
A: Momentary plastic push button switches temporarily interrupt the circuit and are ideal for signal triggering. Latching plastic push button switches use latching relays or bistable circuits to maintain state, reducing wiring complexity and enabling continuous operation.
Q2: Which plastic push button switch is more energy-efficient?
A: Latching switches consume power only during state transitions, while momentary switches continuously draw current while pressed. Latching switches are generally preferred for battery-powered devices.
Q3: Can YIJIA customize illuminated pushbuttons for high-voltage environments?
A: Yes. Our LED switches support voltages up to 380V and are available with optional reinforced insulation (tested to 4kV AC). Custom bezel and shade colors ensure clear visibility even in extreme conditions.
