Provided is an interlock device for a high voltage apparatus which enables not only the diagnosis of the connected or non-connected state of a connector during normal operation of the interlock device, but also the detection of a failure of the interlock device itself, including a failure of the interlock loop. The device includes an interlock loop 16 annexed to an HV connector 7 for connecting an electric compressor to an HV battery 8, a detecting signal output unit, a first switching element, a controlling voltage switching circuit operable, in a closed state of the interlock loop, to switch a voltage applied to a control electrode of the first switching element according to an output of the detecting signal output unit, a second switching element operable, in an open state of the interlock loop, to apply to the control electrode of the first switching element an output of the controlling voltage switching circuit so as to cause an ON/OFF state of the first switching element to be inverted from when the interlock loop is in the closed state, and a failure diagnosis unit.

A coupler between an activator mounted on an enclosure and an electronic protection device located within the enclosure facilitates alignment between the coupler and the electronic protection device during installation and requires no tool for installation. The coupler is positioned over an opening in the electronic protection device and oriented such that a first coupling portion is configured to engage a complementary coupling portion on the electronic protection device. The coupler may be manually mounted, engaging the complementary coupling portions on the door handle coupler and the electronic protection device without requiring a tool for installation. The coupler includes an upper sleeve configured to receive an axle, connected to the activator, that rotates independently of a lower sleeve which is mounted to the electronic protection device, facilitating orientation of the activator on the outside of the enclosure. The coupler provides for local lock-out of the electronic protection device.

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.

A trigger switch assembly for use with an electrical device, including: a switch housing; a switch circuit disposed within the switch housing; an actuator rod configured for operable-interaction with a contact lever of the switch circuit; a trigger member having an actuator rod engagement recess configured for receiving a first end of the actuator rod therein, and, a finger-engagement portion configured for engagement by a user's finger so as to urge the actuator rod along the movement axis from the OFF position in to its ON position; and a lock-off mechanism.

A mechanical latching device of an electromagnetic contactor eliminates a need to adjust a gap between portions mechanically preventing returning of a latch support. A latch support includes a protrusion protruding laterally and formed with a latch surface facing a released side. A rotating member has one end side rotatably supported and the other end side biased toward the protrusion. When the latch support is on the released side, an outer peripheral surface of the other end side contacts with a tip of the protrusion to allow the latch support to be displaced to a closed side. When the latch support is on the closed side, the other end side rotates according to a position of the latch support in a displacement direction, and a tip surface faces the latch surface to mechanically prevent the latch support from returning to the released side at plural positions along the displacement direction.

A power disconnection device for manually disconnecting power of a battery pack, the device including a housing, first and second interlock terminals provided in the housing and connectable to an interlock circuit of the battery pack, first and second high voltage terminals connectable to a high voltage line of the battery pack, a switch lever disposed over inner and outer portions of the housing, a first switch module in contact with the first and second interlock terminals, and upon an off operation of the switch lever, configured to be separated from any one of the first and second interlock terminals, and a second switch module configured to interlock with the first switch module, the second switch module being in contact with the first and second high voltage terminals, separated from any one of the first and second interlock terminals, and then separated from the first and second high voltage terminals.
