SJE-Rhombus Junior Super Single® Pump Switch Description
Mercury Activated, Wide-Angle Switch Designed for Direct Control of Pumps up to 1/2 HP at 120 VAC and 1 HP at 230 VAC.
The Junior Super Single® pump switch is a mercury-activated, wide angle switch designed for direct control of pumps up to 1/2 HP at 120 VAC and 1 HP at 230 VAC in non-potable water and sewage applications. Although this switch is not sensitive to rotation, it is affected by turbulence and should be mounted in a non-turbulent location. The Junior Super Single® pump switch is not recommended for use with motor contactors or relays because the motor contactor or relay may experience chattering. A Super Single® or Double Float® pump switch would operate more efficiently in these installations.
