STAUFF Model DS307 Pressure Switches
This model is a piston-spring type pressure switch. With pressure at zero the micro-switch remains pressed and will only be released when the adjusted switching pressure has been reached. The piston acts against an adjustable spring with travel mechanically limited to 0.5mm, giving minimum work of good resistance to overpressure. The design of the spring .. prevents overtightening. Adjustment by turning the screw top (or knurled knob) which can be fixed with a locking screw. The complete adjusting travel is approx. 9 mm.
