Component Specifications

Definition
Control buttons are momentary or maintained-contact switches integrated into machine control panels, designed for operator interaction to send electrical signals to programmable logic controllers (PLCs) or relay circuits, enabling command execution for machine functions such as start, stop, emergency stop, mode selection, and parameter adjustment.
Working Principle
Control buttons operate on electromechanical switching principles: when pressed, they close or open electrical contacts, completing or interrupting circuits that send low-voltage signals to control systems. Illuminated variants incorporate LEDs or incandescent lamps for status indication. Emergency stop buttons feature a latching mechanism that requires manual reset after activation.
Materials
Button caps: Polycarbonate (PC), ABS plastic, or stainless steel (IP69K rated). Contacts: Silver alloy or gold-plated for low resistance. Housing: Thermoplastic (UL94 V-0 rated) or die-cast aluminum. Seals: Silicone or EPDM rubber for ingress protection.

Frequently Asked Questions

What is the difference between momentary and maintained contact control buttons?

Momentary buttons return to their original position when released (e.g., start buttons), while maintained buttons stay in position until pressed again (e.g., on/off switches).

How do illuminated control buttons indicate machine status?

Illuminated buttons use LED colors: green for normal operation, red for stop/emergency, yellow for warning, and blue for information, following ISO 3864-1 safety color standards.

What safety standards apply to emergency stop buttons?

Emergency stop buttons must comply with ISO 13850 (safety of machinery) and IEC 60947-5-5, requiring direct opening action, positive operation, and manual reset capability.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
