Lift switches are a simple, reliable way to turn off the flow of liquid automatically every time your planter’s bar is raised.
When the bar is lowered, the button is activated which completes the circuit and and turns on the pump. When you lift, the button is deactivated which breaks the circuit and shuts off the pump.
Installation is easy.
BENCO Lift Switch kits consist of an ultra-reliable push button lift switch, the specific mounting bracket for your machine, and the mounting hardware to install it. BENCO lift switches are designed to work with OnSite FMS, BENCO Motor Controllers, most field computers, boom valves, or almost anything else that can accept signal from a lift switch.
BENCO also offer stand-alone kits that use the lift switch to activate boom valves, shutting off the flow of liquid when the bar is raised without the trouble or expense of a field computer. This system is very cost effective and can work with almost any pump on almost any planter. See below for more details.
Please note BENCO recommends using separate lift switches for each system you would like to control. This is due to the different ways in which different systems are wired. Conflicting systems could potentially back-feed power to each other if hooked together at the switch, potentially damaging electrical components.
The BENCO lift switch boom valve kit is a simple way to shut off the flow of liquid on your planter every time you lift the planter bar without complex and expensive electronics. The simple system uses a push-button lift switch (with the correct bracket for your planter) to shut off the flow through up to 2 boom valves.
When the row unit is raised, the lift switch is depressed and sends the signal to close the boom valves. This stops the flow of liquid. Your 12V pump will automatically shut off when 60 pounds of pressure is achieved in the system.
When the row unit is lowered again, the switch sends the signal to resume flow to the valves. As the valves open, pressure in the system drops below 60 pounds and the pump automatically resumes.
