EMAS CP101AA31 is a 22 mm three-position key-operated industrial control switch with two normally open contacts, a single spring-return mechanism, key removal at 0 and IP65 front protection.
£17.83
The EMAS CP101AA31 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 three switch positions, two normally open contacts and a single spring-return mechanism.
This control switch has three positions marked II–0–I, with a 60° switching angle between positions. Its single spring-return design provides one maintained operating direction and one momentary direction that returns automatically when released, offering flexible control from a single key-operated device.
The key can be removed in the central 0 position, helping restrict equipment operation to authorised personnel. With an AC-15 operational current rating of 4 A at 230 V AC, IP65 front protection and a standard 22 mm mounting diameter, the CP101AA31 is suitable for machine panels, operator stations and industrial control enclosures.
Single spring-return key switches combine two operating behaviours within one control device. One outer position provides maintained selection, while the other provides momentary operation and returns when released. This arrangement is useful where an installation requires both a continuous mode and a temporary command.
The EMAS CP101AA31 provides two normally open contacts and a central 0 position within a standard 22 mm format. Key-controlled operation helps manage access to machine functions, while the mixed maintained and spring-return mechanism supports flexible industrial control configurations.

The CP101AA31 provides key-controlled maintained and momentary switching for industrial machinery, electrical panels and automation systems.
The switch has three positions marked II–0–I, with a 60° switching angle between positions.
Single spring return means that one outer position returns automatically when released, while the other outer position remains selected until the key is turned again.
The switch is fitted with two normally open contacts, identified as a 2NO contact configuration.
The key is designed to be removed when the switch is in the central 0 position.
EMAS CP Series control units provide dependable switching, standardised panel mounting and robust protection for industrial machinery, automation equipment and electrical control applications.
