Abstract:
A trigger switch TS includes a trigger that moves in a pulling direction in response to pressure of a pulling operation and moves in an opposite direction to the pulling direction in response to being released from the pressure. The trigger switch TS includes a lock guide 6 (movable engagement member) that moves in conjunction with movement of the trigger, and a ratchet ring 7 (restraint engagement member) that engages with the lock guide 6 to prevent movement of the lock guide 6 in the opposite direction to the pulling direction. The ratchet ring 7 allows the lock guide 6 to move in the pulling direction, and engages with the lock guide 6 to prevent movement in the opposite direction from a position to which the lock guide 6 is moved in the pulling direction.
Abstract:
A portable electronic device including a housing; a button hole formed in the housing; and a button unit arranged in the button hole of the housing is provided. The button unit includes a top button coupled to the housing and covering the button hole, with a first direction length larger than a second direction length; a button frame provided in the housing, with one portion in the second direction coupled to a bottom of the top button and the other portion in the second direction coupled to an internal space of the housing; an actuator projected from a bottom surface of the button frame; and a dome switch pressed by the actuator and generating a signal, when the top button is pressed.
Abstract:
A push switch of an outside handle of a door having a button installed inside a grip cover, wherein the button is attached to the inner surface of the grip cover through a support extending from a side of the button, and a tact switch pressed when the button is pushed.
Abstract:
An actuator is allowed to move toward +A direction and toward −A direction. A movable contact engages with the actuator. A fixed contact touch the movable contact with electrical connection when the movable contact is located at an ON position, and are apart from the movable contact with electrical isolation when the movable contact is located at positions other than the ON position. An arc prevention mechanism prevents arc between the movable contact and the fixed contact.

Abstract:
A switch unit including a case that has an opening and a switch two terminals that partially project to an outside of the case from the opening, a gasket configured to seal the opening, the gasket including two through-holes through which the terminals extend, a base member, and a pressing member that is arranged between the terminals, where the gasket is in close contact with the terminals at the through-holes, a region between the through-holes of the gasket is pressed while nipped between the pressing member and the base member and a surrounding region in the gasket is pressed while nipped between an inside surface of the case and the base member.
Abstract:
A waterproof structure for a press switch of a flashlight is disclosed. The flashlight to be used in water or high-moisture environments has a flashlight body formed as a whole by using a rigid plastic material and the press switch integratedly formed, by using a non-rigid plastic material, about a border between a lighting segment and a handle segment of the flashlight body, so that the press switch combined with the flashlight body as an integrated member is able to form a circuit between conductive contacts inside the flashlight body and batteries assembled between the conductive contacts or break the circuit, so as to turn on or off a light bulb of the flashlight, without the concern that external rainwater or moisture may intrude into the flashlight.
Abstract:
A switch assembly provides a pressing plate on a pivot contact lever to minimize heat generation at the point between the pivot contact lever and the contact point by providing an additional parallel connection contact plate which is in parallel connection to the pivot contact lever. The switch assembly provides convex contact portions on the internal output ports of the forward/reverse switch mechanism. A supplementary elastic metal plate to the pivot contact lever is provided to solve the problem of loose contact at the pivot connection site where the pivot contact lever and the support unit meet, and provides a supplementary contact unit to the movable contact device at the forward/reverse switch mechanism.
Abstract:
In a switch device, such as a horn switch device attached to a steering wheel, a water column is prevented from being formed between contact sections of a pair of contact points facing each other.A movable member (30) and a fixed member (40) of a horn switch device (20) are disposed in an opposed manner such that the movable member (30) on an upper side can be moved toward and away from the fixed member (40) on a lower side and such that it is urged upward by urging means (50). Furthermore, at least a pair of protruding contact points (35) and (45) are formed on the movable member (30) and the fixed member (40), at positions facing each other. By bringing them into contact with each other, the members (30) and (40) are electrically connected, closing a horn circuit. A rivet (46), serving as a contact section, is attached to a tip portion of the fixed contact point (45) on the lower side, and an opening portion (36) is provided in the movable contact point (35) on the upper side, the outer peripheral side of which is made to serve as a contact section to be brought into contact with the rivet (46).
Abstract:
A main switch section is accommodated in a trigger. The trigger provided on the handle through a spring. The handle is formed with a recess to which one end of the spring is seated, so that the trigger is normally urged toward the lower side of the combustion-type nail driver. A switch accommodating portion is provided in the lower side of the canister housing. A push switch is stored in the switch accommodating portion. The push switch is a commodity type micro-switch covered with a switch protection member made from an elastic material such as a rubber
