LPFS331R458A Lovato KEY METAL FLAT SELECTOR 1-0-2 458A

Why Choose the Lovato LPFS331R458A 3-Position Key Selector Switch?

The Lovato LPFS331R458A is a 30 mm flat metal 3-position key-operated selector switch actuator designed for industrial machinery, control panels and automation systems where restricted or authorised operation is required. Part of the Lovato Platinum flat metal Ø30 mm series, it combines a low-profile metal construction with key-operated control and a clearly defined 1-0-2 position arrangement.

The selector provides three positions arranged 1-0-2 and allows the key to be extracted in positions 1, 0 and 2. The 458A key code identifies the key variant, making the actuator suitable for installations where access to machine functions or operating modes needs to be controlled through a specific key.

Constructed from aluminium and zinc alloy, the LPFS331R458A provides a mechanical life of 1,000,000 cycles and IEC protection ratings of IP66, IP67 and IP69K. It is supplied as an actuator without a mounting adaptor and is designed for use with the Lovato LPXAU120M mounting adaptor and compatible contact elements selected to suit the required control circuit.

Key Advantages

• Key-operated 3-position selector helps restrict machine operation to authorised personnel.

Secure 1-0-2 Selection for Industrial Machine Control

Key-operated selector switches are useful where machine modes, functions or operating states should only be changed by authorised personnel. The three-position 1-0-2 arrangement of the LPFS331R458A provides two selectable operating positions separated by a central zero position, while the key-operated mechanism helps prevent casual or unintended changes.

The ability to remove the key in all three positions allows the selected state to be secured against unauthorised adjustment once the key has been withdrawn. Combined with its robust flat metal construction and high environmental protection ratings, the LPFS331R458A is well suited to industrial machinery, production equipment and control panels requiring durable access-controlled operation.
