ABSTRACT:
A linear adjustment operator for pressure control of paint pumps including a base, an electrical switch, a linear actuator, a spring biasing the switch towards the actuator and a lever acting on the actuator for repositioning the actuator with the switch positioned within a range of angular positions to set a desired pressure for the pump by the position of the lever. A slide operator in a bezel is coupled to the lever for adjustment by a user, with plastically deformable parts in interengagement between the operator and bezel to retain the setting selected.
