RJS Electronics PS909 Momentary Push Button Switch, DPDT, Off-(On), 30VDC 100mA

The RJS Electronics PS909 Momentary Push Button Switch provides high reliability and robust electrical performance in a compact, through-hole format. This double-pole double-throw (DPDT) switch features a horizontally actuated momentary action, meaning it is only in the 'On' state while the button is pressed, returning to 'Off' when released. This makes it ideal for applications requiring temporary circuit activation or user input confirmation.

Engineered for durability, the switch utilises high-quality double sliding contacts with silver-plated brass for both contacts and pins. This construction ensures excellent conductivity, low contact resistance, and enhanced resistance to corrosion, contributing to a long operational life and stable performance.

With a maximum contact rating of 30V DC and 100mA, it is perfectly suited for low-voltage control circuits, signal routing, and logic-level switching in a wide array of electronic projects and professional equipment. The through-hole terminals facilitate secure and straightforward soldering onto printed circuit boards (PCBs), providing a reliable mechanical and electrical connection.

Its compact dimensions of 22mm width, 33mm height, and 2mm depth allow for efficient use of space on crowded circuit boards. The momentary 'Off-(On)' operation is a standard and versatile configuration for many control panel and interface applications.

Key Applications

• Control panel interfaces and operator stations.
• Signal switching and routing in test equipment.
• User input buttons in electronic instruments and prototypes.
• Reset or function activation switches in embedded systems.
• General-purpose low-power switching in DIY electronics and hobbyist projects.
