Alarm Controls ON/OFF Key Switch KA-105, Key Removable in ON Position, Keyed Different
Arm it with a turn of the key.
The KA-105 is an ON/OFF key switch with a black button. The key can be removed in the ON position, and it is keyed different, so only the matching key operates it.

Key-controlled arming needs a real switch.
Arming, shunting or door release in access control and security systems should sit behind a key, not an open button. A keyed ON/OFF switch gives installers a clear point of control.
Built for clean installs
The KA-105 comes with the hardware and options installers look for on a key switch.
Key removable in ON
The key can be taken out while the switch is in the ON position.

Available lead length
Leads with fasten terminals are available at 12".
Keyed different
Each switch is keyed different, so keys are not shared across units.
Two nuts provided
The switch is provided with two nuts for mounting.
Leads and guard options
12" leads with fasten terminals, a dress nut and a 10C guard ring are available.
