Why Choose the EMAS CP101AC20 Key-Operated Control Switch?
The EMAS CP101AC20 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 a maintained switching mechanism with two normally open contacts and removable-key operation.
This control switch has two positions marked 0–I, with a 60° switching angle. Its stay-put mechanism maintains the selected position until the switch is deliberately operated again, making it suitable for applications requiring a maintained on or off control command.
Unlike versions that only allow key removal in the off position, the CP101AC20 allows the key to be removed in both the 0 and I positions. With an AC-15 operational current rating of 4 A at 230 V AC, IP65 front protection and a standard 22 mm mounting diameter, it is suitable for machine panels, operator stations and industrial control enclosures.
Key Advantages
- Key-operated control helps manage access to industrial machinery functions.
- Key removal in both positions allows the selected operating state to be secured without leaving the key inserted.
- Two normally open contacts provide control-circuit switching for industrial equipment.
- Stay-put operation maintains the selected 0 or I position until deliberately changed.
- 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

Secure Maintained Control in Either Position
Maintained key switches allow an industrial control circuit to remain in its selected state without requiring the operator to hold the key. Allowing key removal in either position means the equipment can remain securely set to 0 or I while the key is retained by authorised personnel.
The EMAS CP101AC20 provides two normally open contacts within a standard 22 mm panel-mounting format. Its removable-key design is useful where access to both switching positions must be controlled or where the selected operating state should remain unchanged after the key has been removed.
Typical Applications
- Industrial machinery on and off controls.
- Authorised equipment enable controls.
- Production and assembly machinery.
- Conveyor and material handling systems.
- Pump and motor control panels.
- Operator control stations.
- Access-controlled automation systems.

Frequently Asked Questions
What is the EMAS CP101AC20 used for?
The CP101AC20 provides maintained, key-controlled switching for industrial machinery, electrical panels and automation systems.
In which positions can the key be removed?
The key can be removed in both the 0 and I positions, allowing either selected state to be maintained after key removal.
Does the CP101AC20 return automatically to the 0 position?
No. The CP101AC20 has a stay-put mechanism, so it remains in the selected position until it is deliberately switched again.
What contact configuration does the CP101AC20 have?
The switch is fitted with two normally open contacts, identified as a 2NO contact configuration.
What mounting hole does the CP101AC20 require?
The switch is designed for installation in a standard 22 mm panel mounting hole.
