Eaton M22-PVS/KC11/IY Emergency Stop Mushroom Head Key-Operated Switch, 1NC/1NO, 22.5mm, IP66, Red

Unlike standard emergency stop buttons that can be reset by anyone, this Eaton M22-PVS/KC11/IY requires a key to release the mushroom head, ensuring only authorised personnel can restart machinery. The key is removable in both the 0 and I positions, preventing accidental or unauthorised operation. Built for harsh industrial environments, the front is IP66-rated against dust and water jets, while the 22.5mm mounting diameter fits standard control panels. The surface mount enclosure (M22-I1) with insulated plastic construction and screw terminals makes installation straightforward.

Highlights

• Emergency stop mushroom head with key release (key removable in both positions)
• 1 normally open (NO) + 1 normally closed (NC) contact for reliable circuit control
• IP66 front protection against dust and water jets
• Standard M22 mounting diameter (22.5mm) fits most control panels
• Surface mount enclosure (M22-I1) with insulated plastic construction
• Screw terminals for secure wiring, cable entry 2 x M20
• Rated operational voltage up to 500 V AC / 250 V DC
• Rated operational current 6 A (AC-15, 230 V)
• Operating temperature range -25°C to +70°C
• Compliant with IEC/EN 60947-5-1

In daily use

The key can be removed in both the 0 and I positions, preventing unauthorised or accidental resetting. The large red mushroom head is easy to operate, even with gloves, and the high ingress protection makes it suitable for washdown areas and dusty production lines. The positive break operation per IEC 60947-5-1 guarantees that the NC contact opens reliably.
