Why Choose the Lovato LPSS340R3131A Key Selector Switch Actuator?
The Lovato LPSS340R3131A is a robust 2-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 combines durable metal construction with keyed operation for professional industrial control interfaces.
The LPSS340R3131A provides 0 ← 1 spring-return operation, automatically returning from position 1 towards the normal 0 position when released. The key can be extracted in the 0 position, making this configuration particularly suitable for authorised momentary commands where the selector should not remain in the actuated position.
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 LPSS340R3131A is engineered for dependable operation in demanding industrial environments.
Spring return from position 1 to 0 for momentary keyed commands.
Key extraction in the 0 position.
3131A key code for applications requiring a defined key combination.
Durable aluminium and zinc-alloy construction.

Secure Momentary Keyed Control for Industrial Machinery
Key-operated selector switches provide a practical method of restricting important machine commands to authorised personnel. The Lovato LPSS340R3131A combines keyed operation with a spring-return mechanism, allowing an authorised operator to initiate a momentary command from position 1 before the actuator automatically returns towards its normal 0 position.
The Platinum metal series is designed for industrial operator interfaces where durability and environmental protection are important. Its robust metal construction, long mechanical life and high protection ratings make the LPSS340R3131A suitable for machinery, automation panels and operator stations operating in demanding industrial environments.

The selector actuator has two positions configured as 0 ← 1.
Does the LPSS340R3131A return automatically to zero?
Yes. The LPSS340R3131A provides spring return from position 1 towards position 0, so the actuator returns to its normal zero position when released.
Where can the key be removed from the LPSS340R3131A?
The key can be extracted when the selector is in the 0 position.
What key code does the LPSS340R3131A use?
This version uses the 3131A key code, distinguishing it from LPSS340 variants supplied with other key combinations.
What protection rating does the LPSS340R3131A provide?
The actuator provides IP66, IP67 and IP69K IEC protection together with UL Type 1, 2, 3R, 4, 4X, 12 and 12K environmental protection classifications.
Are contact elements and the mounting adapter included with the LPSS340R3131A?
No. The LPSS340R3131A is supplied as the key-operated selector switch actuator without the mounting adapter or contact elements; the compatible mounting adapter is the LPXAU120M.
