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.
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.

The LPSS390R3131A is a 3-position key-operated selector switch actuator used for authorised machine and automation functions requiring both maintained and momentary keyed operation.
The selector actuator has three positions configured as 1–0 ← 2, with a central zero position.
Yes. The selector provides spring return from position 2 towards the central 0 position, allowing position 2 to be used for a momentary keyed command.
The key can be extracted when the selector is in position 1.
This version uses the 3131A key code, distinguishing it from LPSS390 variants supplied with other key combinations.
The actuator provides IP66, IP67 and IP69K IEC protection together with UL Type 1, 2, 3R, 4, 4X, 12 and 12K environmental protection classifications.
No. The LPSS390R3131A is supplied as the key-operated selector switch actuator without the mounting adapter or contact elements; the compatible mounting adapter is the LPXAU120M.
Lovato Electric Platinum-series pushbuttons and selector switches provide durable operator-control solutions for industrial machinery, automation panels and OEM equipment, combining robust metal construction, practical keyed switching and high environmental protection.
