Why Choose the Lovato LPSS380R3131A Key Selector Switch?
The Lovato LPSS380R3131A is a robust three-position key-operated metal selector switch actuator designed for secure control of industrial machinery, electrical panels and automation systems. Part of the Lovato Platinum metal Ø22 mm series, it provides a 1 > 0 - 2 operating arrangement with a special 3131A key code for applications where access to machine functions or operating modes needs to be restricted.
The LPSS380R3131A features a black, non-illuminated key actuator with three positions: 1, 0 and 2. The selector incorporates spring return from position 1 to the central 0 position, while position 2 is maintained and allows key extraction in position 2. This combination makes it particularly useful for applications requiring a momentary command in one direction and a maintained, key-secured state in the other.
Designed for demanding industrial environments, the LPSS380R3131A provides IP66, IP67 and IP69K protection, a mechanical life of up to 1,000,000 operating cycles and an operating temperature range of -25 to +70 °C. Its aluminium and zinc-alloy construction provides excellent durability, while compatibility with the Lovato LPXAU120M mounting adapter enables integration with Platinum-series contact elements.

Secure Momentary and Maintained Key Control
Key-operated selector switches are used where machine commands or operating modes need to be restricted to authorised personnel. The Lovato LPSS380R3131A combines two different operating behaviours in one three-position actuator: position 1 provides a momentary command with automatic return to 0, while position 2 remains selected after operation.
The ability to extract the 3131A key in position 2 allows the maintained operating state to be secured against unauthorised changes. Combined with rugged Platinum-series metal construction, high ingress protection and long mechanical endurance, the LPSS380R3131A provides a dependable solution for machinery, production equipment and industrial operator interfaces.
Typical Applications
- Industrial machine control panels.
- Restricted-access machine controls.
- Momentary and maintained control functions.
- Machine enable and operating-mode selection.
- Automation and process control systems.
- Manufacturing and production equipment.
- Control desks and operator stations.
- Electrical switchboards and control cabinets.
