Two Hand Control Device Safeball™

Safeball™ is an ergonomic control device used for safe start and stop of machine cycles. Usually two Safeball™ are used to-gether to form a two-hand control.

Safeball™ consists of a spherical ball con¬taining two embedded push button switch¬es, one on each side of the ball. Both buttons must be pressed in order to start and oper¬ate the machine. The risk of unintentional ac¬tivation is thereby minimized and the device is simple and ergonomic to use.

When two Safeball™ are used in a two-hand device application, the operator must press all four push buttons simultaneously in order to operate the machine. If one or more of the buttons are released, a stop signal is given to the machine.

Two‑hand control device
A two‑hand control device is often used for machines with manual loading or unloading. The operator uses the two-hand control device to safely start a machine cycle. A two-hand control must be used with a safety control device that makes sure that both buttons are pressed simultaneously, i.e. both hands are on the control and therefore outside the dangerous zone, in order to start the dangerous movement. Using two SafeballTM, it is easy to realize a custom two-hand device.
