Otto P9 Series Momentary Push Button Switch, Grey LED, Panel Mount, SPST, Dome Actuator, 28 V DC 115 V AC, IP68 P9-113128

Otto P9 Series Momentary Push Button Switch model P9-113128 is engineered for robust performance in demanding applications. This industrial-grade switch features a dome-style actuator, delivering positive tactile feedback every time it is pressed. The momentary (spring-return) action makes it ideal for control panels, heavy machinery, equipment consoles, and critical interface points where reliable signaling or control is required.

Designed with a grey LED indicator integrated into the actuator, the switch provides immediate visual feedback for operator status. Its SPST (Single Pole Single Throw) contact configuration ensures straightforward On-On switching, simplifying control circuit integration. The switch is rated for both 28 V DC and 115 V AC operation, accommodating a wide range of voltage levels in modern electrical systems.

The panel cutout size requirement is 0.5 inch, and the switch is equipped with a moistureproof and dust-tight enclosure rated IP68 for enhanced environmental protection. This allows the switch to withstand exposure to water, dust, and extreme conditions without loss of performance. The solder terminal design ensures reliable electrical connections and quick installation in industrial environments.

The P9 Series is mechanically rated for approximately one million cycles at its full load, supporting resistive loads up to 5 A or inductive loads up to 3 A. Its electrical life spans approximately 25,000 operations under specified load conditions. The rugged black bezel and body, combined with a contoured dome cap, aid both aesthetics and durability. Threaded hex nut mounting provides secure attachment and stable operation under shock or vibration.

Applications include industrial automation, machine controls, instrumentation, control grips, computers, heavy equipment dashboards, and any demanding system requiring attractive, reliable push button switches. The P9 Series is recognized for its low contact resistance suited for low-level switching as well, expanding its utility in precision panels.
