Securitron -u.s. MKSA2 Dpdt Add Switch Mk Series

Product Description

The SECURITRON -U.S. MKSA2 is an alternate action double-pole double-throw (DPDT) add switch designed for integration with MK Series exit devices. It provides a latching switching function, toggling between states with each press rather than returning to a default position. This type of accessory switch is commonly used in access control and security applications to signal door position, trigger alarms, or interface with building automation systems. Installation is handled by licensed electricians or security system technicians working on commercial door hardware.

The MKSA2 is intended for use with MK Series exit devices in commercial and institutional settings such as office buildings, schools, and healthcare facilities. It is added to the exit device assembly to provide an additional switching output for integration with security panels, access control systems, or monitoring equipment. The alternate action DPDT configuration makes it suitable for applications that require a maintained contact state rather than a momentary signal.
