摘要： A switch device includes an operation unit, a switch unit detachably attached to the operation unit, and an engagement portion provided at the operation unit. The switch unit includes an opening-closing contact mechanism opened in association with an operation of the operation unit, and a drive portion driving the opening-closing contact mechanism to an open condition at a standby position and to a closed condition at a usage position. When the operation unit is attached to the switch unit, the engagement portion engages the drive portion to drive the drive portion from the standby position to the usage position. When the operation unit is inserted to the switch unit, the operation unit and the switch unit are engaged at the usage position.

摘要： A switch device includes an operation unit having a pushbutton for performing a pushing operation; a switch unit separably joined to the operation unit, the switch unit including an opening-closing contact mechanism opened or closed in conjunction with the pushing operation of the pushbutton of the operation unit, and a rotary drive plate rotating between a standby position and a usage position; and an engagement portion engaging the operation unit to the rotary drive plate to rotary-drive the rotary drive plate from the standby position to the usage position when the operation unit is attached to the switch unit. The operation unit is detached from or attached to the switch unit to set the opening-closing contact mechanism in respectively predetermined opening-closing states.

摘要： A rotational operation type switch includes a frame; a rotational operation button rotatably supported on the frame for rotational operation; a switching contact mechanism disposed below the operation button to face the operation button; and an operation mechanism disposed between the operation button and the switching contact mechanism, to switch the switching contact mechanism in conjunction with the rotational operation of the operation button. The switching contact mechanism includes a printed circuit board, a plurality of fixed contact electrodes disposed on the printed circuit board and spaced a predetermined distance away from each other, and a movable contact having a disc spring shape and disposed bridging between the plurality of fixed contact electrodes. The movable contact deforms to contact and separate from the fixed contact electrodes and switches an electrical connection between the fixed contact electrodes.
