One 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.

One‑hand control device
One Safeball™ can be used as an ergonomic “hold to run” button, i.e. the movement is allowed as long as both push buttons on Safeball™ are pressed, usually when the operator cannot reach the hazardous area with his/her free hand, or on less dangerous machines. SafeballTM is a very practical one‑hand control device since it is very easy to locate and activate.
