Lovato LPSS333R458A is a Platinum metal Ø22 mm three-position 1–0–2 key-operated selector switch actuator with 458A key code, maintained operation, key extraction in position 2 and IP66, IP67 and IP69K protection.

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.
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.

The LPSS333R458A is a 3-position key-operated selector switch actuator used for controlled machine and automation functions where operating-mode selection needs to be restricted to an authorised key holder.
The selector actuator has three maintained positions configured as 1–0–2, including a central zero position.
No. The LPSS333R458A has maintained positions and no automatic return to zero, so the selected position remains mechanically set until the operator changes it.
The key can be extracted when the selector is in position 2.
This version uses the 458A key code, distinguishing it from LPSS333 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 LPSS333R458A 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.
