The CP101AC20 gives you a 2-position key switch that can only be turned to on or off with the key inserted — but critically, the key pulls out in either position, so you can lock a system on or off and walk away without leaving a key in place. That's a common requirement anywhere unauthorised operation (or unauthorised shutdown) needs to be prevented. It's priced well below premium-brand equivalents and held in UK stock for fast dispatch.
Example Applications:
- Lock Off EV Charge Points
- Outdoor Equipment
- Alarm Systems
- Final Exit, master on/off
- Shutters and Doors
- Industrial Machines

Frequently Asked Questions
Can the key be removed in both positions?
Yes — this is a "stay put, key removal at all positions" design, so the key comes out whether the switch is left in the on or off position, letting you secure it either way.
What's the difference between this and the CP101AC30?
This CP101AC20 is a simple 2-position on/off switch. The CP101AC30 adds a centre-off position with two selectable outer states (e.g. "Manual - Off - Auto"), for applications needing a 3-way lockable selection rather than just on/off.
Is this suitable for outdoor installation?
Yes — IP65 rated, protected against dust ingress and low-pressure water jets, suitable for outdoor equipment like EV charge points.
Does it come with multiple keys, or are they keyed alike across units?
Check with EMAS or your supplier on key uniqueness if you need site-wide keyed-alike or keyed-different configurations for multiple installations.
Industry Applications
- EV charging infrastructure — lockable master on/off to prevent unauthorised charge point use
- Security & access control — final exit master switches, alarm system arming/disarming
- Outdoor & shutter/door equipment — weatherproof lockable control preventing tampering
