A switch device includes a casing that includes a recessed bearing portion, a rotatable drive member that includes a shaft portion disposed in the bearing portion, a switch driven by the drive member, and a covering member that includes a pressing structure provided so as to press an upper portion of the shaft portion and that is secured to the casing. The covering member includes an operating portion that faces the drive member such that the operating portion is able to press the drive member and that is formed of an elastically deformable elastic material and a base portion that is secured to the casing, that is formed of a synthetic resin material, and that is integrated with the operating portion. The pressing structure is integrated with the base portion and formed of an elastically deformable elastic material.

A circuit breaker includes a main body case, an operating handle having a base portion and a knob portion protruding outwardly through a handle window frame opened in a cover of the main body case; a first shutter arranged between the base portion of the operating handle and the handle window frame, and disposed on the base portion, the first shutter being formed with a loose-fit hole to loosely fit the knob portion therethrough; and a second shutter disposed on the first shutter to move along with the knob portion. At ON and OFF positions of the operating handle, the first shutter extends beyond a front/rear edge of the handle window frame in a front-back direction to close the handle window frame, and the second shutter extends beyond a front/rear edge of the loose-fit hole in the front-back direction to close the loose-fit hole.

A switch unit includes an upper case that has an operation portion attached therein; a circuit board that has a switch attached thereto that is able to switch contact points by operation of the operation portion; and a lower case that fits into the upper case such that the lower case is surrounded by the upper case, and that accommodates the circuit board between the upper case and the lower case. A draining portion is provided at a side surface of the upper case, and the draining portion is integrally formed with a sidewall forming the side surface and protrudes downward, and has a width that gradually narrows from the top to the bottom thereof.

An actuating device for an electromedical apparatus and in particular a foot switch. The foot switch includes a floor part, at least one pedal part that is tiltably connected to the floor part, and at least one switch element that is actuated by the pedal part. Further, at least the floor part is manufactured by one of an extrusion-coating method or a casting method such that at least a portion of the floor part is fully coated by a coating material.

An electric switch module has one or more electric switches arranged on a substrate (7) of which at least one is designed as a push-pull rocker switch (2, 3) having an actuator (4) formed by a projection (5) that is asymmetrical to its tilting axis (6). The module is characterized in that the top side of the substrate (7), together with the actuators (4) of its switches (2, 3), is covered by a flexible outer skin (10a) that also covers the projection (5) that forms the actuator (4) of the at least one rocker switch (2, 3).

A switching device has a switch, a case within which the switch is accommodated, a cylinder which is provided on an upper surface of the case and open to above and below to communicate with the inside of the case an operation knob which covers an opening of the cylinder and swings in a front-to-rear direction, and an operation bar which extends from the operation knob through the opening into the case to transmit the motion of the operation knob to the switch. A guide member is disposed between the case upper surface and the end of the operation knob. The guide member is inclined in the left and right directions so as to guide water toward the sides of the case.

A switch assembly may include a housing having a body and an over-molded feature. The over-molded feature may include a flexible membrane sealingly engaged with the body and defining an actuation portion. The housing may be configured to sealingly engage a finish panel. A back cover may sealingly engage the housing, and a rocker may be included between the actuation portion and the back cover to transmit a force applied to the actuation portion to actuate a switch.

A foot switch which comprises a housing member defining a hollow cavity bounded by front, back and side walls with a pair of spaced apart rib members within the housing spaced intermediate the side walls. Journaled between each side wall and a rib are generally U-shaped members having a first treadle and a second operating arm. The second arms are journaled in the housing and one of the ribs and the first treadle arms are accessible without the housing and adapted to rotate the first arms upon application of pressure. A torsion spring is positioned about each of the second arms between a side wall and a rib and arranged to bias the second arms into a predetermined position. At least one switch having an actuating arm is secured in the housing member. Switch arm actuating members are also secured within within the housing to act on the switch arms and are actuated by the second arms of the U-shaped members when the first arms are depressed under foot pressure. When depressed, the first arms rotate the second arms against the bias of the torsion springs to actuate the switch actuating arms through the switch actuating members.

The protective electrical switch cover is in the form of a generally flat, flexible, resilient plate of extended surface area and with memory. Preferably, the cover is of elastomeric electrically insulative plastic and/or rubber and is unitary. It includes a generally central, hollow, protruding nipple adapted to receive the arm of an electrical switch over which the cover is to be mounted, as by an adhesive layer on the rear surface of the cover. The nipple is surrounded by a number of spaced encircling folds or rings which permit the nipple to be readily flexed in a plurality of directions in order to operate the switch arm. Thus, through the nipple, the switch arm can be rotated or flipped in a desired direction and can be pushed in and pulled out, depending on the type of switch arm involved. Moreover, the encircling folds can be depressed at a desired location to operate the switch arm if it is of the rocker type. The assembly of the present invention includes the cover mounted over an electrical switch having the protruding switch arm. The mounting area is outside of the area of the nipple and rings.
