The Alderon Industries VertiMAC pump switch, distributed by JMI Pump Systems, is a pipe-mounted vertical float that operates in the same fashion as a typical vertical switch, with a piggyback plug and needing only the space of the rod to operate its float. This switch allows a sensor and reed switch to mount to the top of the pump switch, transforming the switch into the Sump Advisor, which adds an 84 dB high-water alarm along with pump run indicator lights. Featuring a 9-volt battery pack in case of power loss, it also comes with dry contacts in the alarm box to connect to any existing security systems. 800-234-5490; www.jmipumps.com.
