A device for moving a door provided in an air conditioner upstream of an area in which cold air and hot air are mixed to produce a stream of air having an appropriate temperature includes an electric motor which is rotatable in either direction for rotating the door in either direction. An electric switch is connected to the motor for controlling its operation. The switch is reciprocatively slidable by a lever. A cam follower is connected to the motor reciprocatively slidably in parallel to the switch for changing an electrical circuit connection between the switch and the motor. The cam follower is connected to the motor by a wire and the door is also connected to the motor by a wire. The switch has a rotatable arm which is engageable with the cam follower. The arm has a neutral position in which it is engaged with the cam follower so that no electric current may be supplied to the motor. The arm is rotatable in two opposite directions from its neutral position. If it is rotated in either direction, the motor is rotated for moving the cam follower toward the switch until the arm is brought back to its neutral position.

Air conditioner with motor controlled door

An air conditioner control system for adjusting the mixing ratio of warm and cool winds by controlling the opening angle of the air mixing door of an air conditioner. The control system includes a base board formed with for wiring patterns and a contact lever made swingable on a common point shared with the base board and carrying a pair of sliding contacts for sliding into selective contact with the wiring patterns. The contact lever is adapted to engage with a control knob, and the base board is connected to a motor actuator. The air mixing door is opened or closed in accordance with the movement of the control knob so that the base board may accordingly be swung in the lever moving direction.

Air conditioner control system

A thin type push-button switch of momentary operation, comprising a movable contact piece which includes an inversion portion and arms formed in a manner to hold the inversion portion therebetween. The inversion portion is formed with a movable contact portion having tongues, and is integrally formed of a resilient metal sheet. A case includes a groove held in engagement with one of the arms and stationary contacts are fixed within the case. A slider includes a push-button portion and a groove held in engagement with the other arm and is slidable with respect to the case. When the push-button portion is depressed, the inversion portion of the movable contact piece is inverted to electrically connect the movable contact portion and the stationary contacts. When the depressing force is released, the inversion portion is restored by the resiliency of the movable contact piece, to disconnect the movable contact portion and the stationary contacts.

Push-button switch

A ganged push-button switch assembly having a plurality of switch blocks mounted in a common frame. Each switch block has an operation rod movable inwardly beyond a latchable position, a casing adapted to fit in corresponding mounting opening formed in the frame and a cover member attached to the casing and slidably receiving the operation rod. The casing has resilient arms adapted for engagement with the mounting opening of the frame, while the cover member has a pair of retainers engageable with the casing and is provided at its portion projecting forwardly from the frame with a groove which receives an engaging portion projected from an interlocking plate common to the switch blocks.

Ganged push-button switch

A lever switch has an actuating member and a cover member to be connected to each other. The actuating member includes first and second slots and notch portions. The cover member includes legs to be engaged with the notch portions of the actuating member. The first slot of the actuating member acts as a guide when it is attached to a mounting rod, and the second slot of the actuating member may support the mounting rod after the actuating member and cover member are connected, whereby the actuating member may be rotatably and removably attached to the mounting rod.

Lever switch with improved actuating member

A push-button electrical switch is described having an illuminated window showing the status of the switch. The window includes the words 'ON' and 'OFF' in differing but complementary colors and two filter members also of differing but the same complementary colors are rotated selectively into the light path to the window in order to illuminate either the word 'ON' or 'OFF'.
