Lovato LPSB6842R458A is a black Ø40 mm metal mushroom-head pushbutton actuator for normal stopping, featuring maintained latching, 458A key-operated release, Ø22 mm panel mounting and IP66, IP67 and IP69K protection.

The Lovato LPSB6842R458A is a robust metal mushroom-head pushbutton actuator with key release designed for normal stopping and controlled machine operation. Part of the Lovato Platinum metal Ø22 mm series, it features a large black mushroom head and a maintained latching mechanism that requires the correct key to release the actuator.
The actuator has a Ø40 mm black mushroom head that provides a prominent operating surface for machinery and industrial control panels. Once pressed, the actuator remains latched until released by turning the key, helping provide deliberate and controlled resetting of the stop command.
Designed for a standard Ø22 mm panel opening, the LPSB6842R458A uses durable aluminium and zinc-alloy metal components with polyamide plastic components. It provides IP66, IP67 and IP69K protection and has a mechanical life of up to 300,000 cycles, making it suitable for demanding industrial control environments.
Maintained mushroom-head pushbuttons are designed to remain mechanically latched after they are pressed rather than returning automatically to their normal position. The Lovato LPSB6842R458A requires a key-operated release, helping ensure that resetting is a deliberate action carried out using the appropriate key.
Its large Ø40 mm head, rugged metal construction and high ingress-protection ratings make the actuator well suited to industrial operator stations and machine-control panels. The LPSB6842R458A is intended for normal stopping applications and should be combined with the appropriate Lovato mounting adapter and contact elements for the required electrical control circuit.

The LPSB6842R458A is a maintained mushroom-head pushbutton actuator for normal stopping in industrial machinery and control-panel applications, with a key required to release the latched actuator.
The actuator uses a latch and turn-key-to-release mechanism. After the mushroom head has been pressed and latched, the appropriate key is turned to release it.
The LPSB6842R458A has a prominent Ø40 mm black mushroom head and is designed for installation in a Ø22 mm panel opening.
The actuator is rated IP66, IP67 and IP69K according to its IEC specifications, supporting installation in demanding industrial environments when correctly assembled.
The LPSB6842R458A is specified by Lovato for normal stopping. It should not be treated as an emergency-stop actuator solely because it has a mushroom-shaped head; the applicable machine safety requirements and correctly specified emergency-stop components should be used where an emergency-stop function is required.
Lovato Electric Platinum-series pushbuttons and selector switches provide durable operator-control solutions for industrial machinery and automation systems, combining robust construction, practical panel mounting and reliable mechanical operation.
