LA38-11ZS "STOP" Emergency Stop Switch

Product Description
The LA38-11ZS "STOP" Emergency Stop Push Button functions as a robust 22mm Push Button Switch and heavy-duty Control Panel Push Button. As a dependable Machine Emergency Stop Button, this Mushroom Emergency Stop Switch acts as a vital Industrial Safety Switch for plant-floor protection. Designed for emergency power-off tasks, this Emergency Stop Push Button fits a wide range of industrial machinery and control cabinet installations.

Product Appearance & Dimension
Built as a standard Mushroom Emergency Stop Switch, this unit comes with a 40mm diameter red mushroom head printed with high-visibility "STOP" identification and white twist-reset directional arrows. The overall assembly height ranges from 78mm to 80mm, and its contact base measures 32mm × 29mm. Designed for 22mm panel cut-out mounting, this 22mm Push Button Switch features a sandblasted outer lid delivering matte anti-fingerprint performance. Auxiliary indicator lamp variants can also be selected when configuring this Control Panel Push Button.

Material & Construction
Housing and inner components adopt high-quality imported raw materials. This Machine Emergency Stop Button is assembled with thickened silver-alloy contacts to guarantee stable current transmission and arc resistance. A built-in dust-proof base together with a dust-proof cover minimizes dust contamination inside the chamber. Snap‑fit split‑modular design enables fast disassembly of the mushroom head and contact block for installation and on‑site maintenance. Contact blocks can be freely stacked to achieve multi‑loop signal output. The transparent contact block allows direct visual inspection of the internal contact state without full disassembly, a practical feature for this Industrial Safety Switch.
