Why Choose the Lovato LPSS390R3131A Key Selector Switch Actuator?
The Lovato LPSS390R3131A is a robust 3-position key-operated selector switch actuator designed for industrial machinery, automation systems and electrical control panels where access to operating functions needs to be restricted. Part of the Lovato Platinum metal Ø22 mm series, it provides a durable keyed operator for professional industrial control interfaces.
The LPSS390R3131A provides a 1–0 ← 2 operating configuration, with position 1 maintained and spring return from position 2 towards the central 0 position. The key can be extracted in position 1, making this configuration suitable for applications requiring a maintained authorised selection together with a momentary keyed command.
This variant uses the 3131A key code and features a black, non-illuminated actuator manufactured from aluminium and zinc alloy. With IP66, IP67 and IP69K IEC protection and a mechanical life of 1,000,000 cycles, the LPSS390R3131A is engineered for dependable keyed control in demanding industrial environments.

Secure Maintained and Momentary Keyed Control
Key-operated selector switches provide a practical method of restricting important machine functions and operating-mode changes to authorised personnel. The Lovato LPSS390R3131A combines a maintained position 1 with spring-return operation from position 2 towards the central 0 position, allowing maintained and momentary control functions to be incorporated into a single keyed operator.
Key extraction in position 1 enables an authorised operating state to remain mechanically selected after the key has been removed. Combined with robust metal construction, a long mechanical life and high environmental protection ratings, the LPSS390R3131A is suitable for demanding machinery, automation panels and industrial operator stations.
Typical Applications
- Industrial machinery control panels.
- Authorised machine operating-mode selection.
- Maintained and momentary keyed control functions.
- Machine enable, reset and control circuits.
- Automation and process-control systems.
- Operator stations and industrial control consoles.
- OEM machinery and electrical control cabinets.
