Medium Duty Wide-Angle Mini Mercury Pump Switch

Mercury-Activated, Wide-Angle Pump Switch

The Medium Duty Wide-Angle Mini Mercury Pump Switch is designed for direct control of pumps up to 1/2 HP at 115 VAC and 1 HP at 230 VAC.

This mercury-activated, wide-angle pump switch provides automatic control of smaller pumps 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 Medium Duty Wide-Angle Mini Mercury pump switch is not recommended for use with motor contactors or relays because the motor contactor or relay may experience chattering. A Medium Duty Wide Angle Mercury or Medium Duty Wide Angle Dual pump switch would operate more efficiently in these installations.
