Description
The DS-501 Momentary Push Button Switch is a reliable control component engineered for a 14mm mounting hole, making it ideal for industrial control panels, electromagnetic starters, and contactors. Featuring a “Press-OFF, Release-ON” (Normally Closed / NC) configuration, this switch is designed to break the circuit when pressed and automatically reset upon release.
Constructed with durable ABS material, the DS-501 is built to handle frequent operation in demanding environments. It is a robust choice for circuit control, offering a mechanical lifespan of 50,000 cycles and low contact resistance (≤50mΩ) for efficient signal transmission. Whether for professional industrial machinery or sophisticated DIY electronic control systems, this switch provides the stability and performance required for secure circuit management.
