GEMS PS41-20-4MNS-A-FLS18-IP-FS1BARR Pressure Switch
PS41 Series Pressure Switches are designed for demanding applications where space and/or price are a concern. These switches utilize a piston/diaphragm design, which incorporates the high proof pressure of piston technology with the sensitivity of diaphragm designs. Switches are field adjustable via an Allen head screw that is hidden to protect against unauthorized tampering.
