Universal Pneumatic Switch


The PS20 pneumatic switch offers a reliable, low cost signalling alternative. The PS20 switch enclosure accepts an air hose connection. When the attached hose is compressed and air is forced into the diaphram, it activates a switch. The signal is sent to the motor controls via wired (PS20A) or wireless (PS20-RF) transmission.
