To realize both toughness and size reduction of a safety switch. A safety switch is a safety switch into and from which a bolt of an actuator is inserted and pulled out. The safety switch includes a casing having a shape elongated along a first direction, a metal head having a receiving space for receiving the bolt of the actuator and provided on a first end side of the casing in the first direction, a detector for detecting a first state in which the bolt is received in the receiving space, a lock mechanism, a switching device and a first attachment portion provided in the head and having a first attachment hole into which a first attachment member is inserted.

An industrial locking switch comprises multiple locking tongue entry slots formed on adjacent sides of the locking switch housing, thereby supporting receipt of the corresponding locking tongue from multiple directions of approach without the need to mechanically modify the switch's head or to reorient the switch itself. The locking switch houses locking bolt detection circuity comprising multiple series connected RFID coils configured to detect an RFID tag mounted on the locking tongue when the locking tongue is inserted into any of the entry slots.

An electric vehicle is supplied with power from a power supply via a cable suspended from an anchor. The anchor is attached to a mount on the vehicle and detachable from the mount by tension in the first portion of the cable between the anchor and the power supply. A second portion of the cable between the anchor and the vehicle remains slack in the attached position of the anchor, and extends on detachment of the anchor to relieve tension in the first portion of the cable. A disconnection switch is operable by detachment of the anchor to interrupt the power supply from the cable to the vehicle.

The invention relates to a safety switch assembly (100) having a switch installation (120) having at least one switching member (12) and at least one actuation installation (110) having at least one assigned actuator (13, 13′, 13″, 14), wherein a transmission installation (130) having at least one transmission member (135) which is coupleable or coupled to the switching member (12, 12a), on the one hand, and to the at least one actuator (13, 13′, 13″, 14), on the other hand is provided between the actuation installation (110) and the switch installation (120). In order to have available a safety switch assembly (100) in which a mechanical fault does not lead to a failure of that functionality that optionally permits the integration of a diagnostic function in order for the system in the case of a fault being detected to be able to be brought back to a safe state and that permits a transfer of mechanical as well as of electrical/electronic functions across the entire system, it is provided that the transmission installation (120) is provided with a plurality of separate transmission members (135) which in the actuation of the at least one actuator (13, 13′, 13″, 14) of the actuation installation (110) are drivable or driven in a synchronous and mutually independent manner, and that each of the transmission members (135) by way of a rotary movement is permitted to convert an actuation movement of the at least one actuator (13, 13′, 13″, 14) to a translatory movement of in each case one separate switching member (12, 12a) of the switch installation (120). (FIG. 4).

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 with a lock-out device comprises a switching unit (2) adapted to be anchored to a fixed part of a structure and provided with switching means adapted to be operatively connected with at least the power supply circuit of the plant to be controlled for the opening/closing thereof, an operating unit (3) adapted to be anchored to a movable part of the structure and having actuating means (5) adapted to interact with the switching means upon the closing of the movable part on the fixed part to enable the closing of the power supply circuit, a lock-out device (16) associated with the switching unit (2) and having a guard (17) movable between an inactive position adapted to allow the interaction between the switching means and the actuating means (5) and an active position wherein the interaction is avoided. The switching means and the actuating means (5) are of the electronic type and are respectively associated with a first communication element (6) and a second communication element (7) adapted to remote communicating therebetween by means of a presence signal and to allow the switching means to discriminate the presence of the operating unit (3) close to the switching unit (2). The movable guard (17) comprises a shielding element (20) adapted to interpose itself between the communication elements (6, 7) when the guard (17) is into the active position to avoid the transmission of the signal and the closing of the switching means.

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.

This service plug (1) has a connection terminal part (49), and the connection terminal part (49) has a pair of terminals (8) and an interlinking part (9) that is tailored to the spacing between the terminals (8) and joins the terminals (8) together. By removing the connection terminal part (49) from a power-supply circuit, the power-supply circuit is interrupted. The interlinking part (9) includes one or more thin interlinking plates (20) that are removably attached to the connection terminal part (49).
