A pressure switch including: a spring blade; a ram pin having an angled bottom surface and laterally restrained in movement, where upward movement of the ram pin engages the spring blade such that the spring blade snap deflects to an engaged position, and where downward movement of the ram pin engages the spring blade such that the spring blade snap deflects to an unengaged position; a ball bearing in contact with the angled bottom surface of the ram pin; and an adjustment screw laterally restraining the ball bearing in movement, where a lateral inward movement of the adjustment screw relative to an outside surface of the pressure switch causes an upward movement of the ram pin, and where a lateral outward movement of the adjustment screw relative to the outside surface of the pressure switch causes a downward movement of the ram pin.

A flow switch including: a fluid inlet for receiving fluid in-line relative to a flow switch body; a poppet valve disposed in the fluid inlet and having a variable location relative to the flow switch body; an actuator pin affixed to the poppet valve; a helical spring disposed about the actuator pin, where the poppet valve is spring-loaded via the spring; and where the spring-loaded poppet valve is configured to move away from the fluid inlet with increasing volumetric fluid flow and towards the fluid inlet with decreasing volumetric fluid flow.
