I'm looking to hook up 2 pneumatic switches to a 6v mini linear actuator. The switches are pressure and vacuum. I want to push air into one switch to make the actuator extend and suck into the other switch to make the actuator retract.
Does anyone know how to reverse polarity with the 2 switches rather than the standard dpdt momentary toggle switch?
They have a high pressure side port and a low pressure side port. If you push air(pressure) into the high side port, contact is made between the 2 terminals. If you suck air(vacuum) on the low side port, contact is made between terminals. 6volt Nimh battery- 2200 maH. Imagine a piece of tubing in user's mouth connected to a barbed tee, where 1 tube goes to the high port on 1 switch, and 1 tube goes to low port on other switch.
The linear actuator is energized by reversing polarity. 2 wires coming out of actuator- reverse polarity on those 2 wires to change direction.
