KAC offers the Class 9000 range of actuation devices that feature a variety of different operating mechanisms.
The Class 9000 units have numerous applications across the fire, security, machine operation and other industries where manual control of specific operations is required.
The various options within the range enable operation with or without security restrictions.
The keyswitch units are available as two and three-position devices and provide protection against unauthorised operation with removable keys.
They control two independent circuits.
In the two-position versions one circuit is open while the other is closed; turning the key reverses these positions.
In the three-position version both circuits are normally open; either one is closed depending on which way the key is turned.
As a further refinement, the key can be removed in either one or both positions for the two-position keyswitch; in the three-position version the key is removable in all three positions.
The push-button units are double pole and available as either momentary action, with the circuit completed only while the button is pushed, or as latching units that toggle between the open and closed state on successive operations.
The two or three-position rocker switch units are available as two-position, double-pole on/off switches, or three-position, double-pole on/off/on devices, with all switches rated at 230V AC.
All units are available with red, green, white, yellow and blue bodies and in a choice of flush or surface mounting variants.
