Description
The DS-501 Momentary Push Button Switch is a rugged, panel-mount control component engineered for applications requiring a “Normally Closed” (NC) circuit configuration. Featuring a “Press-OFF, Release-ON” action, this switch is designed to break the circuit when depressed and automatically reconnect when released. Its 14mm threaded mounting diameter ensures a secure, vibration-resistant fit for industrial control panels, contactors, and electromagnetic starters.
Constructed from high-grade, durable plastic, the DS-501 offers excellent electrical conductivity and reliable performance in demanding environments. The vibrant red cap provides clear visual indication, making it an ideal choice for emergency stops, safety interrupts, or signal-breaking functions in both professional machinery and custom DIY electronics projects.
