Hands-free control device 325 for remotely controlling valves which control fluids or other devices requiring such control. The hands-free control device 325 works by compressing movement control devices housed in the centre of the hands-free control device 325 between a base plate 101 and an upper floating plate 211 secured to the base plate 101. The hands-free control device 325 can work with temporary fixed or variable alternative controlled actuation positions, when the upper floating plate thereof is displaced towards the rear end thereof, or with permanent fixed positions when the upper floating plate thereof is displaced to the front end thereof. The movement control devices may control other devices, such as valves for controlling fluids or other devices requiring such control, via mechanical, hydraulic, pneumatic or electrical control lines. The hands-free control device 325 may be operated with the feet or other parts of the body. |
