摘要： There is provided a multistage push-on switch used in input operation sections in various electronic apparatuses. In particular, there is provided a push-on switch in which a first-stage switch turns on with an operation force lower than conventionally achievable and the resultant on-state is easily retained. The push-on switch is configured such that movable contact (7) having projecting segment (11) permanently connected with outer contact (41) is accommodated in recess (21A) of switch enclosure (21), on which sheet (50) with center through hole (50A) for movable contact (7) is placed. The push-on switch also includes metal cover (13) with a cover terminal. Metal cover (13) is attached to switch enclosure (21) such that pressing segment (13C) faces off against disc segment (8) of movable contact (7) corresponding to the position of the center through hole (50A) with a predetermined vertical gap between pressing segment (13C) and disc segment (8). When a very low and weak force is applied on pressing segment (13C), it comes into contact with disc segment (8) to change the state of the first-stage switch.

摘要： In a switch, an elastic member made of elastic material includes a bar section, a conical section at its upper portion functioning as a first deforming section, and a second deforming section at its lower portion. A movable contact in a switch case is pushed with the lower end portion of the second deforming section. A bar section of an elastic element projects through a central hole of a cover fixed to the switch case. In this switch, a pushing force applied to the elastic element deforms the first deforming section elastically, and then the second deforming section deforms elastically, and thus, the switch operates. The switch can absorb fluctuations due to combination of components of an electronic appliance, and stabilize its manipulation feeling through eliminating looseness of an operation button of the appliance.

摘要： A push switch which includes a switch case, a first movable contact, and a second movable contact. The switch case has a central fixed contact on an inner bottom face of its recess that has an open top, and a peripheral fixed contact. The first movable contact is curved protruding upward, and has a hole at its center. The first movable contact is disposed over the peripheral fixed contact with a space in between. The second movable contact is curved protruding upward, and is placed on the first movable contact. A pressing force for resiliently inverting the second movable contact is set greater than a pressing force for resiliently inverting the first movable contact; and two tactile feedbacks are produced by pressing from a side of the second movable contact.
