Embodiments provide a terminal, and the terminal includes a body, a cover body covering the body, a circuit board mounted in the body, a central processing unit welded on the circuit board, a control part mounted on the cover body, and a protection switch welded on the circuit board. A hard disk slot for accommodating a hard disk is disposed in the body. The cover body is detachably mounted on the body, and is configured to seal the hard disk in the hard disk slot. The cover body is opened to drive the control part to open the protection switch. An electrical signal variation is generated due to opening of the protection switch. After detecting the electrical signal variation, the central processing unit instructs the hard disk to perform data protection and powers off the hard disk.

A kill switch including a switch assembly. When the switch assembly moves from a switch first configuration to a switch second configuration with the switch assembly operatively connected to a controller of a tractor, a kill electrical signal is provided to the controller to stop the tractor powering a power take-off thereof. A cord is securable to the switch assembly and to the piece of machinery to extend along a rotary drive shaft between the tractor and the piece of machinery. A switch actuating element extends from the cord, the switch actuating element being removably securable to the switch assembly. In the switch first configuration with the switch actuating element secured to the switch assembly, the switch actuating element maintains the switch assembly in the switch first configuration. When the switch actuating element is removed from the actuating element receiving portion, the switch assembly moves to the switch second configuration.

A safety device with a safety switch and an actuator that is arranged movably relative to said safety switch. A transponder is arranged in the actuator, and a reading unit is arranged in the safety switch. A locking position of the actuator is controlled by the fact that transponder signals of the transponder are detected in the reading unit. The safety switch has a locking element with an influencing element. The actuator has a sensor coupled with the transponder. In the locking position of the actuator the locking element is insertable into a receptacle of the actuator. This effects the locking of the actuator. This locking is controlled in that the influencing element is only within the range of influence of the sensor when the locking element is inserted into the receptacle. Said sensor generates a sensor signal via which the transponder signals sent by the transponder are modified.

The present invention relates to motor safety devices as used in increasing numbers for the killing of engines or disengaging propulsion units from motors, when there are no operators to maintain control of an apparatus or vehicle such as jet-ski, boat, go-kart and the like or personnel to oversee use of a motorised tool or the like. Motor boat operators on a boat have been known to fall overboard without being detected by the operator of the boat. Such runaway boats have been known to seriously injure the operator of the boat in the water since a runaway boat tends to circle back to the place where the operator has fallen overboard. The present invention is also applicable to other types of equipment such as motorised gymnasium equipment, hand operated power tools, such as agricultural and arboriculturist equipment and wood working tools.

An electronic operated safety switch has a switching device which houses a switch. The switch is operatively connected to a control or service circuit. The electronic operated safety switch also has an operating device configured for engaging the switch. The switching device comprises a head housing a sensor, and a case housing a lock. The operating device is adapted to send a signal to the sensor, thereby controlling the switch. The switch comprises an actuator housed in the case, the actuator configured to operate on the lock upon the receiving by the sensor of the signal.

A circuit board enclosure comprises a circuit breaker, platform, base, cover, and circuit board. The circuit breaker includes two conductors and a plate, which is connected to the conductors. The platform receives the circuit breaker. The base has a bottom member and an opening arranged in the bottom member. The base receives the platform with the circuit breaker such that the plate of the circuit breaker is accommodated substantially within the opening of the bottom member. The cover is configured to cover the base and form an interior space. The interior space accommodates the platform, the circuit breaker, and the circuit board. The circuit board is connected to the circuit breaker. The circuit board enclosure can be adhered to a substantially planar surface. The plate is configured such that removal of the circuit board enclosure from the substantially planar surface will damage the connection of the plate to the conductors.

A safety switch for guarding access comprises a case housing switching means suitable for being connected to one or more power and/or service circuits of the machine or plant for their opening and/or closing upon interaction with an actuating device, a locking/unlocking mechanism of the actuating device housed in the case and provided with a movable locking/unlocking pin along a longitudinal direction to protrude at least partially with one of its ends from the case, a head fixed to the case and configured to allow the interaction of the locking/unlocking pin with the actuating device, mutual coupling means between the case and the head suitable to allow their mutual stable fixing by relative sliding along at least one sliding direction transverse to the longitudinal direction.

A safety switch for guarding accesses to industrial machines or plants comprises a case which extends along a main dimension defining a longitudinal axis of development, control means housed in the case and suitable for receiving and exchanging signals with the actuating device and/or with the machine or plant and provide with a first PCB, a head connected to the case and adapted to interact with the actuating device upon the opening/closing of the access and wherein the first PCB comprises a first longitudinal portion housed in the case and a second longitudinal portion housed in the head.
