Why Choose the Lovato LPFS390R3131A Key Selector Switch Actuator?
The Lovato LPFS390R3131A is a robust 3-position key-operated selector switch actuator designed for industrial machinery, automation systems and control panels where access to operating functions needs to be restricted. Part of the Lovato Platinum flat metal Ø30 mm series, it provides a durable, low-profile keyed operator for professional industrial control interfaces.
The LPFS390R3131A provides a 1–0 ← 2 operating configuration, combining three selector positions with a spring-return function from position 2 towards the central 0 position. The key is extractable in position 1, making the actuator suitable for applications requiring a maintained authorised selection alongside a momentary keyed command.
This version uses the 3131A key code and features a black, non-illuminated actuator. With IP67 and IP69K front protection and NEMA Type 4X front protection, the LPFS390R3131A is well suited to industrial machinery, operator stations and control cabinets exposed to demanding operating conditions.

Secure Keyed Control for Industrial Machinery
Key-operated selector switches provide a practical way to restrict important machinery functions and operating-mode changes to authorised personnel. The Lovato LPFS390R3131A combines three selectable positions with spring-return operation from position 2 towards the central 0 position, allowing maintained and momentary control functions to be incorporated into the same operator interface.
The key-extraction arrangement in position 1 enables a selected operating state to remain established after the authorised operator removes the key. Combined with its flat-metal Platinum construction and high front protection ratings, the LPFS390R3131A provides a practical solution for demanding industrial machinery and automation installations.
Typical Applications
- Industrial machinery control panels.
- Authorised machine commands and access control.
- Machine operating-mode selection.
- Momentary and maintained keyed control functions.
- Automation and process-control systems.
- Operator stations and industrial control consoles.
- OEM machinery and electrical control cabinets.
