A method of applying a switch locking device to a wall switch to prevent actuation of the wall switch. The wall switch has an actuator member extending through a toggle frame in a switch plate. With the switch in the desired on or off position, the snap-on locking device will be placed in the gap between the actuator member and the toggle frame. Operation of the switch is prevented by the arm of body that goes between the actuator member and the toggle frame surface.

An operation element is disposed in a recess provided in a lower surface of a controller attached to a vehicle ceiling part, and the operation element comprises an inclined portion inclined at an upward gradient from a vehicle front toward a vehicle rear, a protruding portion formed by the inclined portion, and provided on a vehicle front side of a point, on the operation element, that has an equal distance from opposite ends of the operation element in a front-back direction, and an operating rotary shaft disposed on a side of the protruding portion.

A safety lockout device can include a main body, a receiving portion of the main body configured to receive a portion of an arm of an electrical switch, and a locking portion of the main body configured to be inserted into a receiving portions of the electrical switch.

Disclosed is an air circuit breaker including a safety cover. According to embodiments disclosed herein, a setting unit of an overcurrent trip relay exposed to the outside through an opening is covered by the safety cover, and thus manipulation of the setting unit is not allowed before opening the safety cover. Accordingly, an accident due to malfunction or manipulation of the overcurrent trip relay by an unauthorized person may be prevented.

A trigger assembly for an electrical device that includes a main body having a housing within which an electrical switch unit is disposed. The trigger assembly may include a trigger member having an engagement portion that is hingedly connected to the main body so that the trigger member is rotatable about a hinge relative to the main body. The trigger assembly may include an actuator member operably-connected to the trigger member that is movable between an OFF position and an ON position. The trigger assembly may include a lock-off mechanism including a lock-off member that is selectively operable to restrict movement of the trigger member towards the main body and to thereby restrict movement of the actuator member from the OFF position into the ON position, and, to not restrict movement of the trigger member toward the main body.

A load detection sensor unit 1A includes: a load detection sensor 5 that has a sensor sheet 50 having a pair of resinous insulating sheets 56s and 57s, a first electrode 56e provided on a surface of one insulating sheet 56s, and a second electrode 57e forming a pair with the first electrode 56e, and a metal plate 60 provided in at least a portion overlapping with the first electrode 56e and the second electrode 57e on one surface of the sensor sheet 50; and a pressing member 4 that has a pressing portion 46 disposed on the side of the metal plate 60 opposite to the side of the sensor sheet 50 and pressing the metal plate 60. The pressing portion 46 is harder than the seat cushion SC and the sensor sheet 50 and the metal plate 60 are bonded by an adhesive layer 70.

An electronic switch includes a rubber sheet that includes a first surface, a second surface opposite to the first surface, and a convex portion on the first surface. The convex portion of the rubber sheet includes a semispherical shape.

An electromagnetic double-armature relay with an excitation coil comprises a first yoke and a second yoke, which are arranged on the excitation coil. The first leg of the first yoke serves as a support for a first armature and the first leg of the second yoke serves as a support for a second armature. The double-armature relay has a first comb which cooperates with the first armature, and a second comb cooperates with the second armature. In addition, the double-armature relay has at least two contact bridges, each of which is detachably arranged with a first end in the first comb and the second end in the second comb and comprises two contact rivets oriented in opposite directions, and fixed contacts which are arranged opposite the contact rivets of the contact bridge. The arrangement of the two yokes and armatures are such that the two combs perform opposing translational movements.

A surgical footswitch having elevated auxiliary buttons is provided. In particular embodiments, the surgical footswitch comprises a footswitch base, a treadle mounted on the footswitch base, a first primary button positioned on an upper surface of the footswitch base along a first lateral side of the treadle, a first auxiliary button housing positioned along a lateral side of the first primary button opposite the treadle, and a first auxiliary button mounted on an upper surface of the first auxiliary button housing, wherein an upper surface of the first auxiliary button is elevated in relation to an upper surface of the first primary button. In particular embodiments, the treadle is configured to activate a first function of a surgical console, the first primary button is configured to activate a second function of the surgical console, and the first auxiliary button is configured to activate a third function of the surgical console.

Safety switch for a gardening device driven by a motor. The safety switch includes a main button arrangement and a sub button arrangement which is provided onto the main button arrangement. The main button arrangement may pivot between a first position and a second position. In the first position the sub button arrangement may be provided in an arrest position and in the second position the sub button arrangement is arranged in an energize position. Further, the sub button arrangement includes biasing means by means of which biasing means the sub button arrangement is biased towards the arrest position in the first position, and by application of an external force the sub button arrangement may be moved towards a biasing force exerted by the biasing means and be slid to the energize position where the main button arrangement may activate the power means in the second position.
