Honeywell AML27 Series Electronic Control Keylock
The AML series from Honeywell features a wide selection of pushbutton, rocker and toggle switches. They offer not only a wide selection of options such as solid state, electronic and power duty control but also each version offers a number of choices for mounting style, illumination, contact configurations and more. Illuminated versions have easy access to the lamp from the front of the panel for re-lamping, without the need for tools. The AML27 series is ideally suited to applications where the user needs to enable control of access to computer peripherals, keyboards, point-of-sale terminals, and security systems which are locked when unattended and other locations where tampering must be diskouraged.
