Rotary switches and associated methods. A rotary switch can include one or more arcuate passages which are prone to ingress of particulate or liquid contaminants. A gasket, a rib, and/or a lubricant reservoir can be provided in the arcuate passages for blocking ingress of contaminants to an interior of the switch.

A manipulation device includes a rotary knob, a button and a waterproofing ring. The rotary knob rotatable about a rotational axis. The button having a center axis on the rotational axis of the rotary knob. The waterproofing ring that waterproofs a gap between the rotary knob and the button. The waterproofing ring rotating with the rotary knob, and the waterproofing ring being held in contact with the button and the rotary knob.

A rotary switch fitted with signalling means to provide a visual indication of the operating condition of an actuator device, comprising a switch body made of metal or coated externally in metal and a cover is provided. The cover may be joined to close the switch body by means of a plurality of attachment screws in metal or externally coated in metal, each housed in seats arranged in the cover and in the switch body. In particular, inside the seat of the switch body there may be an insert made of a material suitable to prevent the circulation of galvanic currents between the seat of the switch body and the attachment screw.

A switch actuator device is disclosed. The switch actuator device includes a switch housing, a body having a first and second arm, and a resilient member having a first and second end. The first and second ends of the resilient member are configured to be coupled to the body and switch housing, respectively. The resilient member exerts a first force on the body when the body is at a first position, a second force when the body is at a second position, and a third force when the body is at a threshold position. When the body is rotated about a pivot point from the first to second position, or vice versa, the respective first or second force increases in magnitude and acts on the body to first resist the rotation until the body is in the threshold position, and then assists the rotation.

A remotely-controlled rotary disconnecting switch that includes an operating device and a switch body, which includes at least one switch unit. Each switch unit includes a moving contact assembly and a static contact. The operating device drives the moving contact assembly to rotate to be connected to or disconnected from the static contact to connect or disconnect. The operating device includes an operating shaft, a real-time energy storage mechanism, a delayed energy storage mechanism, a locking mechanism with a locking fastener and a tripping mechanism with a trip that actuates to drive the locking fastener to be unlocked from the delayed energy storage mechanism, the delayed energy storage mechanism releases energy to drive the operating shaft to rotate to an opening position, and then the operating shaft drives the real-time operation mechanism to drive the remotely-controlled rotary disconnecting switch to be switched to an opened state.

The invention relates to a switch having a switch housing, a number of module-type individual interrupter chambers which can be arranged in particular side by side in the switch housing and having at least two switching contact elements, and an actuating device which closes off the switch housing above the individual interrupter chambers. This actuating device serves to adjust a cam element for the selective establishment of an electrical connection between the switching contact elements of an individual interrupter chamber. The switching contact elements can be arranged in at least two different orientations in each individual interrupter chamber in an explosion-protected manner. Furthermore, in particular the cam element of the actuating device can be arranged differently depending on the orientation of the switching contact elements. This results in a switch with a simple adaptation option for housing installation or front-panel mounting, wherein all requirements for explosion protection are also fulfilled at the same time.

A switching unit (200) including a membrane (202), a housing (210), at least one rotary switch (204), at least one knob (216), and a sealing member (214). The membrane (202) defines a first opening (230) adapted to receive a portion of at least one rotary switch (204). The housing (210) defines a second opening adapted to be aligned with the first opening (230) to receive the portion of the at least one rotary switch (204). The at least one rotary switch (204) is disposed in the housing (210). The at least one knob (216) mounted on the at least one rotary switch (204). The sealing member (214) is positioned on the housing (210) in the second opening (231), around the at least one rotary switch (204), between the at least one knob (216) and the housing (210).
