An apparatus for preventing over-discharging according to various embodiments of the present invention may comprise: a housing including a first opening; a first electronic component disposed inside the housing; a second electronic component electrically connected to the first electronic component; and a switch for electrically connecting or disconnecting the first electronic component and the second electronic component through an external force by a pin inserted through the first opening. In addition, various embodiments may be possible.

A high power, single-use electrical switch includes a spring-biased plunger contact that mates with a corresponding socket contact, a spacer that provides a separation clearance between the contacts prior to activation of the switch, and a shear tab that supports the spacer and is removed from the switch to enable engagement between the contacts and activation of the switch. Using the shear tab for activation of the switch enables a compact and small form factor assembly that is suitable for use in smaller electronic assemblies.

An actuator (3) for a safety switch (2) with an actuator head (8), said actuator head being mounted to a core body (6) by means of a connection element (7). The actuator head (8) has, at least in parts, a larger cross section than the connection element (7). The connection element (7) is rigid in the axial direction. The actuator head (8) is held in a base position by means of the connecting element (7). In this base position, the longitudinal axis of the connection element (7) runs at an angle of inclination to the surface of the core body (6).

A modular structure for safety switches for controlling access for machines and industrial plants comprises a casing (2) housing switching means for controlling one or more circuits of the machine or plant, drive means adapted to interact with the switching means upon the opening/closing of the access, an auxiliary module (3-3.sup.v) housing at least one control (4.sup.i-4.sup.v) adapted to be manually operated to operate on the switching means and/or the drive means and comprising a box hollow body (5) having at least one opening (6) for inserting the control (4.sup.i-4.sup.v) provided with first means for removably connecting the control (4.sup.i-4.sup.v), the latter being selected within a series of controls (4.sup.i-4.sup.v) having functions different from each other and each provided with a fastening rod (7.sup.i-7.sup.v) adapted to be inserted in the opening (6) of the box body (5) and provided with second connecting means complementary to the first connecting means.

A connector 10 disclosed by an embodiment includes a cover (service cover 20) having a cover housing 21 and a cover connector 40, the cover connector 40 being integrally provided to the cover housing 21, and a device-side connector 50 having a receptacle 52, the cover housing 21 being fittable into the receptacle 52, a mating connector 60 configured to close an interlock circuit by being connected to the cover connector 40 being disposed inside the receptacle 52. The cover housing 21 includes preceding guide portions 27 configured to guide the cover connector 40 into a proper posture to be connectable to the mating connector 60 by sliding on an opening edge part 56 of the receptacle 52 prior to the connection of the cover connector 40 and the mating connector 60.

A method for consigning a function of an electrical device includes: a) receiving a request to consign a function implemented by a sub-assembly of the electrical device, the request being transmitted by a client terminal connected to the control unit via a short-range communication link; b) generating a digital key including a unique identifier; c) storing one copy of the generated key in a memory of the control unit and sending another copy of the generated key to the client terminal that transmitted the request; d) consigning the function so as to prevent this function of the device from being used by the control unit as long as the consignation is active.

A service plug (1) is provided with a female connector housing (20) including a plurality of female terminals (30), and a male plug (10) detachably mountable into the female connector housing (20) along an insertion direction. The male plug (10) includes one male terminal (11) that is long in the insertion direction. Each female terminal (30) includes a female body (31) dimensioned to receive the male terminal (11) therein. The female bodies (31) are aligned coaxially with the inserting direction. The one male terminal (11) is inserted into the coaxially aligned female bodies (31) so that the female terminals (30) and the one male terminal (11) are connected electrically by mounting the male plug (10) into the female connector housing (20).
