| 摘要 | A deadman switch system includes a primary deadman switch actuator and a secondary deadman switch actuator for controlling the flow of an air/abrasive mix through a flow line of a delivery system. The secondary deadman switch is positioned in series with a primary deadman switch actuator such that the controlled flow will not function unless first the primary deadman switch and then the secondary switch are closed. The preferred embodiment of the switch is a low-profile configuration adapted to be mounted in axial alignment with the flow line in a manner to minimize interference with normal operation of the system. The switch can include multiple open/close elements, for selectively controlling different flow functions. | ||||||
