Green Square OFF-ON Push Button – DS-431 2-Pin Momentary Switch (Self-Reset, NC Break Contact)

The Green Square OFF-ON Push Button (Model: DS-431) is a high-quality, momentary action switch designed for precision control in low-voltage applications. This switch features a self-reset mechanism with normally closed (NC) contacts, meaning the circuit remains closed until the button is pressed—breaking the connection momentarily. Its square green cap provides high visibility and a firm tactile response, making it ideal for environments where safety and clear indication are critical.
