An electronic control unit (1) or an electric actuator (2), respectively, have a switch-off device (4) which includes at least one reed switch (6, 18, 26) and at least one permanent magnet arranged outside the housing (3) and removable from the housing (3). If the permanent magnet (7) is removed from its position of usage at the housing (3), for example in order to perform maintenance of the electronic control unit (1) or of the actuator (2), respectively, the at least one reed switch (6, 18, 26) is opened, as result of which the supply link (8, 10) between the activating terminal (5) and the supply terminals (9, 11) of the control unit are interrupted in order to switch voltage-carrying functional elements of the control unit (1) and/or of the electric actuator (2) to be currentless and thus to effectively prevent an unwanted spark discharge.

The disclosure provides a non-contact switch device for use on material handling equipment, including a reed switch and a magnet, wherein the non-contact switch device has on and off positions achieved by the presence or absence of magnetic induction between the magnet and the reed switch. The non-contact switch devices are disclosed in the form of a main power switch, an interlock switch, a limit switch.

An enclosure for a video camera and light, the enclosure including a housing; an internal body secured within the housing; one or more connections extending from the housing; an end plate secured to the housing, a first window extending through the end plate; and a second window extending through the end plate; an end cap secured to a second end of the housing and to seal the internal body within the housing; a video recorder positioned within the internal body and positioned such that a field of view extends out of the first window; a light positioned within the internal body, the light being independent of the video recorder and positioned such that a beam of light extends out of the second window and parallel with the field of view; a magnet holder extending from the housing; and a magnet within the magnet holder and engaged magnetically with a switch associated with the light; dislodging the magnet from the magnet holder causes the switch to activate the light.
