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.
