Push Button Switches
ALX-PB22-M11Z-J Emergency Stop Push Button Switch | 22mm 11
22 mm mushroom head metal push button switch, 1 NO + 1 NC contact, non-illuminated, plug-in pin (j) termination, IP65/IP67, 250 V AC 5 A / 10 A / 18 A. OEM branding and bulk supply from ALUX.
A 22 mm mushroom-head emergency stop switch for industrial control panels. The red mushroom actuator is easy to hit with a gloved hand and stays latched down until you twist it back up, so the stop command is unmistakable and stays in place. Wire the NC contact into the safety relay input - if the cable breaks, the loop opens, the relay drops out and the machine stops.

Design Features
- Metal housing in stainless steel, aluminium alloy or nickel-plated brass - pick the finish that suits the panel without changing the cutout
- Double-break slow-action contact: two contact gaps in series, so the arc is split and contact life is extended
- Contact resistance <= 50 mOhm and insulation resistance >= 1000 MOhm for stable signal and control-circuit duty
- IP65 / IP67 at the panel face - sealed against dust and water jets for washdown and outdoor installations
- Rated for -25 C to +55 C and 45-85 %RH, 1500 V AC dielectric strength for one minute
- Latching action: push to stop and lock, twist to release - the stop state is maintained until an operator resets it
Applications
Machine tools, conveyor and packaging lines, industrial control cabinets, power distribution panels, lifts and hoists, outdoor plant and any station where a safety stop is required by regulation.
