Our exclusive supplier of mechanical pressure switches is Fox s.r.l.       Fox K4 Serie data sheet: Fox K4     “K4” adjustable pressure switches permit opening or closing of an electric circuit upon reaching predetermined pressure value . The preset pressure is found by rotating the external screw located at the centre of the instrument clockwise to increase and vice-versa to decrease the pressure set point value. Mechanical stops protect both the spring and the micro-switch. from over pressurization. The main characteristic of this series is that this miniature pressure switch can be totally dismantled.           Fox F4 Serie data sheet: Fox F4       “F4” adjustable pressure switches allow a micro-switch commutation once a preset pressure value is reached. The set point is adjusted working on the central screw (P3 execution) or intercepting the regulation dowel situated inside the instrument, using a 2mm hexagonal key (M2 and M3). Rotating clockwise the set point is increased and vice-versa is decreased. Mechanical stops protect both the spring and the micro-switch from over pressurization.           Fox F3-K3 Serie data sheet: Fox F3-K3       F3” and “K3” adjustable pressure switches allow the commutation of a micro-switch with exchange contacts once a preset pressure value is reached. The preset pressure regulation is adjusted by the regulation dowel situated inside the instrument that can be intercepted with a 2mm hexagonal key. Mechanical stops protect both the spring and the micro-switch from over pressurization.         Fox F3S Serie data sheet: Fox F3S         “F3S” adjustable pressure switches allow the commutation of a microswitch with exchange contacts once a preset pressure value is reached. The preset pressure regulation is effected on the regulation knob inside the instrument and interceptable through a 2mm hexagonal key. The “F3S” execution is provided with a bigger diameter membrane that allows an excellent working operation at low pressure.           Fox K6-KR6 Serie data sheet: Fox K6-KR6     “K6” and “KR6” adjustable electro-mechanical pressure switch, with exchange contacts, are suitable for application where is not necessary to modify frequently the operating point. The regulation screw, interceptable with a 2mm hexagonal key in the executions “KR6” and “K6/M3”, is situated inside the instrument, protected by an upper cap or a connector against accidental manumissions. Concerning the execution “K6/M12”, the operating point can be pre-settled in factory, or in alternative the Customer can adjust the value removing the four screws on the top of the instrument.           Fox K7 Serie data sheet: Fox K7       “K7” adjustable pressure switches allow the commutation of a micro-switch with exchange contacts. The switching point is adjustable...
