Variable Level Control Switches

• Float is constructed of durable PVC/polypropylene encasing variable level switch
• Standard mechanical variable level control switches
• Temperature rating of 140° F (60° C)
• 18/2 type SJOW CPE cord standard
• Long cords are available in 15', 25', 35' and 50' (5 m, 8 m, 11 m and 15 m) 
• Pipe clamp or adjustable weight mounting types
• Low current switches, 30 VDC/.1 amps, for Class I, Division 1, Group C & D locations when used in intrinsically-safe circuits
• Approximately 1/2" (50 mm) liquid level differential in switching action

Variable level control switch is normally open when hanging vertically above liquid level. Switch closes when it reaches a few degrees above the horizontal position. Applications:

• Switch for simplex or duplex pump control and high level alarm on electrical alternating control panel systems for dewatering, effluent and sewage applications
• Switch for A-Pak
• High level alarm switch
