A rotary combined switch structure with multistage switch function includes a casing unit, a switch unit and a rotary unit. The casing unit has a casing, a first opening formed on a top side of the casing and a second opening formed on a bottom side of the casing. The switch unit is disposed under the casing. The rotary unit has a rotary body. The rotary body has a top portion passing through the first opening and exposed above the casing, and the rotary body has a bottom portion passing through the second opening and exposed under the casing in order to selectably turn on or turn off the switch unit.

A moisture-proof rotary switch structure includes a casing unit, a substrate unit and a rotary unit. The casing unit has a casing, a first opening formed on one part of a top surface of the casing and a second opening formed on a bottom side of the casing, and the other part of the top surface of the casing is sealed. The substrate unit is disposed on the bottom side of the casing for sealing the second opening, and the substrate unit has a substrate and a plurality of conductive areas formed on a top surface of the substrate. The rotary unit has a rotary body and a conductive piece disposed around the rotary body. The conductive piece is selectably electrically connected between two of the conductive areas, and the rotary body has a top portion passing through the first opening and being exposed above the casing.

A moisture-proof push-type switch module includes a first casing unit, a second casing unit, a first movable structure, and a push structure. The first casing unit has a first outer moisture-proof structure disposed around its outer side. The first casing unit has a first receiving room, a second receiving room, and an opening communicating between the second receiving room and the external environment. The second casing unit is mated with the first casing unit. The second casing unit has a second outer moisture-proof structure and a first movable element moisture-proof structure, and the first outer moisture-proof structure and the second outer moisture-proof structure are mated with each other. The first movable structure has a first movable element mated with the first movable element moisture-proof structure. The push structure passes through the opening in order to selectably push the first movable element.

A rotary switch includes a holder base holding two metal contact plates and one metal connection plate, a rotary handle vertically pivotally coupled to a pivot shaft of the holder base and rotatable relative to the holder base between a first position where a bottom recess of a circular actuating member of the rotary handle receives a respective electric connection portion of each metal contact plate and the electric connection portion of the metal connection plate contacts the electric connection portions of the metal contact plates and a second position where a protrusion of the circular actuating member forces the electric connection portion of one metal contact plate away from the metal connection plate to produce an electrical signal, and a torsion spring sleeved on the rotary handle with its two ends respective connected to the actuating member and the holder base for returning the rotary handle automatically after each rotary motion.
摘要:
An axially-movable rotary switch includes a casing, a fixing base, a substrate and a knob. The fixing base is fixed in the hollow casing. The substrate is fixed below the fixing base. The knob is pivotally disposed on the upper end of the hollow casing. The switching rod of the knob eccentrically penetrates a positioning hole of the fixing base. The elastic piece is disposed at the distal end of the switching rod and is brought into contact with the electrical contacts of the substrate. With the elastic piece of the switching rod being arranged to correspond to the electrical contacts of the substrate, a user can switch the states between a closed circuit and an open circuit by axially drawing/pressing the knob. Further, the contact between the elastic piece and the electrical contacts will not generate unnecessary frictional interference, so that the lifetime of the device can be extended.
