Junior Super Single®

Mercury-Activated, Wide-Angle Pump Switch

Pump switches provide automatic pump control.

The Junior Super Single® pump switch is designed to directly control pumps up to 1/2 HP at 120 VAC and 1 HP at 230 VAC in non-potable water, water and sewage applications.

Although the Junior Super Single® pump switch is not sensitive to rotation, it is affected by turbulence and should be mounted in a non-turbulent location.  It 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.

U.S. Patent No. 4,529,854 and 4,572,934
