This switch assembly is all mechanical, no AC or DC power is required, only the opening or closing of a switch take place as liquid raises the displacers.

The Model 6761P2 Displacer Switch assembly is installed on the top of a tank mounted on a 4" flange. This switch assembly provides two (2) points of level detection. As liquid in the tank rises and comes in contact with the displacers a switching action takes place. This switch is all mechanical, no AC or DC power is required, only the opening or closing of a switch take place as liquid raises the displacers.



The Model 6693 Operation Checker (diagram shown with a displacer switch) permits an operator to check the operation of the switches without removing the switches' protective cover. This is an optional recommended accessory. The standard materials of construction of the Model 6761 is aluminum housing and flange, stainless steel isolation tube, stainless steel cable, PVC displacers and all trim parts stainless steel.

The switches are of the encapsulated mercury type with the following ratings: 10 amps at 30 VAC, 5 amps at 115 VAC, 2.5 amps at 220 VAC. Other switches, flange sizes or threaded connections, and materials are available.
