This SPST OFF(ON) type switch momentarily closes the circuit when pressed and returns to the off position when released-making it ideal for applications like reset buttons, test circuits, or user inputs requiring tactile feedback.
The switch is rated for 3A at 125VAC, ensuring reliable performance in low- to moderate-current applications. Built from copper alloy contacts with silver or gold plating, it offers excellent conductivity, low contact resistance, and long operating life. Designed for both reliability and ease of installation, the R18-21B RED ensures dependable switching over 30,000 electrical and 50,000 mechanical cycles.
