Why Choose the Lovato LPSS333R458A Key Selector Switch Actuator?
The Lovato LPSS333R458A 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 LPSS333R458A provides 1–0–2 maintained operation with three stable selector positions and no automatic return to zero. The key can be extracted in position 2, allowing an authorised operating state to remain selected after the key has been removed.
This variant uses the 458A key code and features a black, non-illuminated actuator manufactured from aluminium and zinc alloy. With IP66, IP67 and IP69K IEC protection, a mechanical life of 1,000,000 cycles and a wide operating temperature range, the LPSS333R458A is engineered for dependable keyed control in demanding industrial applications.

Secure Three-Position Keyed Control for Industrial Machinery
Key-operated selector switches provide a practical method of restricting machine functions and operating-mode changes to authorised personnel. The Lovato LPSS333R458A provides three maintained 1–0–2 positions, allowing an operator to deliberately select between two operating states and a central zero position without automatic spring return.
Key extraction in position 2 allows the selected state to remain mechanically established while the key is removed, helping prevent unauthorised alteration of the control setting. Combined with robust metal construction, a long mechanical life and high environmental protection ratings, the LPSS333R458A is suitable for demanding machinery, automation panels and industrial operator stations.
Typical Applications
- Industrial machinery control panels.
- Authorised machine operating-mode selection.
- Key-controlled manual and automatic mode selection.
- Direction or function selection circuits.
- Automation and process-control systems.
- Operator stations and industrial control consoles.
- OEM machinery and electrical control cabinets.
