Why Choose the EMAS CP101AA20 Key-Operated Control Switch?
The EMAS CP101AA20 is a durable 22 mm key-operated control switch designed for controlled operation of industrial machinery, electrical panels and automation systems. As part of the EMAS CP Series, it combines a robust plastic construction with two normally open contacts and key-controlled access.
This stay-put control switch uses two defined positions marked 0–I, with a 60° switching angle. The key can only be removed in the 0 position, helping prevent unauthorised operation while allowing responsible personnel to control access to machinery and electrical equipment.
With an AC-15 operational current rating of 4 A at 230 V AC, an IP65 protection rating and a standard 22 mm mounting diameter, the CP101AA20 is suitable for installation in industrial control panels, operator stations and machine control enclosures.
Key Advantages
- Key-operated control helps restrict machinery operation to authorised personnel.
- Two normally open contacts provide simultaneous switching for two control circuits.
- Stay-put operation maintains the selected position until the key is turned again.
- Key removal in the 0 position supports controlled machine isolation and access management.
- IP65 protection provides resistance to dust and water jets when correctly installed.
- Standard 22 mm panel mounting simplifies integration into industrial control equipment.

Controlled Operation for Industrial Machinery
Key-operated control switches provide a physical method of restricting access to machine functions. The removable key allows authorised personnel to manage who can activate a control circuit, making this type of switch suitable for machinery, maintenance controls and operator panels where accidental or unauthorised operation must be reduced.
The EMAS CP101AA20 uses a maintained switching mechanism, so the selected position remains active until the key is deliberately turned. Its two normally open contacts allow two control circuits to be switched together, while the standard 22 mm mounting format supports straightforward panel installation.
Typical Applications
- Industrial machinery control panels.
- Production and assembly equipment.
- Conveyor and material handling systems.
- Pump and motor control panels.
- Operator control stations.
- Maintenance and service controls.
- Access-controlled automation systems.
