Why Choose the EMAS CP101AA21 Key-Operated Control Switch?
The EMAS CP101AA21 is a robust 22 mm key-operated control switch designed for controlled operation of industrial machinery, electrical panels and automation systems. Part of the EMAS CP Series, it combines two normally open contacts with a spring-return mechanism and key-controlled access.
This control switch has two positions marked 0–I and a 60° switching angle. Turning the key from 0 to I operates the contacts, while the spring-return mechanism automatically returns the switch to the 0 position when released. The key can be removed in the 0 position, helping restrict equipment operation to authorised personnel.
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 CP101AA21 is suitable for machine control panels, operator stations and industrial control enclosures.
Key Advantages
- Key-operated control helps prevent unauthorised machinery activation.
- Spring-return operation automatically returns the switch to the 0 position when released.
- Two normally open contacts allow two control circuits to be operated simultaneously.
- Key removal in the 0 position supports controlled access to equipment functions.
- IP65 front protection provides resistance to dust and water jets when correctly installed.
- Standard 22 mm panel mounting simplifies installation in industrial control equipment.
Key Features
- EMAS CP Series plastic control unit.
- 0–I two-position key-operated switch.
- 60° switching angle.
- Spring-return switching mechanism.
- Key removable in the 0 position.
- 2NO contact configuration.
- 4 A at 230 V AC operational current rating for AC-15 applications.
- Flame-retardant V0 PA6.6 contact blocks.
- Silver-nickel AgNi contact material.
- IP65 front protection.
Momentary Key-Controlled Machine Operation
Spring-return key switches provide momentary, access-controlled operation of industrial equipment. The operator must hold the key in the active position to keep the normally open contacts closed, and releasing the key allows the mechanism to return automatically to its normal 0 position.
The EMAS CP101AA21 is suitable for control functions where a maintained command is not required. Its two normally open contacts can operate two control circuits together, while key removal at 0 helps ensure that equipment cannot be activated without access to the key.
Typical Applications
- Industrial machinery start and control functions.
- 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.
