Securitron MKAN2 DPDT Alternate, Narrow Mortise Keyswitch

The MK series Mortise Keyswitch Panel permits use of any standard US 1-1/4" or 1-1/8" mortise cylinder to operate a switch. A 1 1/2" cylinder can be used if a spacer ring is added to make it protrude 1/4" from the rear of the face plate. The MK can be used for electric lock control, alarm panel arming and similar requirements. The assembly supplied includes a face plate with mounted bicolor LED, bracketry and one or two switches. The user must supply the cylinder and cam as this is typically incorporated into a master key system.

The part numbering for the series works as follows: MK denotes a brushed stainless steel single gang outlet box cover mount and MKN denotes a stainless steel 1-3/4" narrow style plate. The unit is delivered standard with a spring loaded momentary SPDT switch. The addition of the suffix "A" denotes an alternate action switch.

A second switch ordered separately can be affixed to the unit so that turning the key left will depress one switch and turning it to the right will depress the other. Momentary and alternate switches may be combined on the same unit. To order extra switches, the Securitron part number for a momentary switch is MKS. For an alternate switch, (push on, push off), the part number is MKSA. The addition of the suffix, "2" denotes a DPDT switch (MK2, MK2SA etc).
