£25.48
The EMAS CP101AA30 is a robust 22 mm key-operated control switch designed for controlled selection of industrial machinery, electrical panel and automation functions. Part of the EMAS CP Series, it combines three maintained positions with two normally open contacts and key-controlled access.
This stay-put control switch has three positions marked II–0–I, with a 60° switching angle between positions. The selected position remains engaged until the key is deliberately turned again, making the CP101AA30 suitable for applications requiring maintained directional or function selection.
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 switch is suitable for industrial control panels, operator stations and machine enclosures.
Three-position key switches provide controlled selection between two machine functions and a central neutral position. The maintained mechanism keeps the selected function active without requiring the operator to hold the key, making it suitable for applications such as directional control, operating-mode selection and controlled equipment activation.
The EMAS CP101AA30 uses two normally open contacts and clearly defined II–0–I positions. Its removable key helps manage access to machine functions, while the standard 22 mm mounting format supports straightforward installation in compatible control panels and operator stations.

The CP101AA30 provides key-controlled selection between two maintained machine functions and a central 0 position in industrial control and automation systems.
The switch has three positions marked II–0–I, with a 60° switching angle between positions.
No. The CP101AA30 has a stay-put mechanism, so it remains in the selected position until the key is deliberately 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.
