Abstract: An electromagnetic relay includes an electromagnetic unit, a magnetic moving subunit, a first conduct, a second conduct, a movable lead, and a movable contact. The movable lead has a swing portion and a resilient linkage portion. The movable contact is disposed on the swing portion. When the electromagnetic unit is energized, the magnetic moving subunit is attracted by the electromagnetic unit and pushes the resilient linkage portion of the movable lead such that the resilient linkage portion urges the swing portion to swing and that the movable contact disposed on the swing portion is urged to be in contact with one of the first contact and the second contact. When the electromagnetic unit is de-energized, the electromagnetic unit ceases to attract the magnetic moving subunit such that the movable contact is in contact with the other one of the first contact and the second contact.

Each of the clamping plates has a main portion extending from the base member, a clamping portion extending from the main portion in a direction away from the entrance hole, and a pressed portion extending from the clamping portion away from the base member. The receiving space has a quadrilateral cross section, is constricted in the direction and receives the lead. The clamping portions removably clamp the lead. Each clamping portion has a height less than that of the main portion.

Abstract: A pushbutton switch for a switch assembly includes a pushbutton unit and a resilient member. The pushbutton unit includes a mounting seat and a pushbutton that covers the mounting seat. The resilient member is disposed between the mounting seat and the pushbutton, and has an insert connected to the mounting seat and having opposite ends that are spaced apart in an extending direction, and two resilient arms extending respectively from the opposite ends of the insert. Each resilient arm has two contact end sections abutting against the pushbutton and spaced apart in a transverse direction, and is deformed when the pushbutton moves to a contact position so as to generate a restoring force which urges the pushbutton to a non-contact position.

The insulative body includes a base that has a base upper wall, a base lower wall, and two base sidewalls. The base lower wall has a rear end notched in a frontward direction to form a plurality of alternating shallow and deep notches to position first and second legs of the first and second terminals, which are bent downwardly. The alternating shallow and deep notches space the first legs apart from the second legs, respectively. The number of component parts for assembly is therefore reduced.

Abstract: A pushbutton switch includes a shell body, a resilient member, and a movable unit movable relative to the shell body between an upper limit position and a lower limit position. The movable unit includes a drive member and an electrical contact member driven by the drive member to move between a plurality of contact positions and a plurality of non-contact positions. The drive member has a plurality of inclined rod-engaging surfaces. When the movable unit is moved from the upper limit position to the lower limit position, one of the rod-engaging surfaces moves on a guide rod of the shell body, thereby resulting in rotation of the drive member relative to the shell body so as to covert the electrical contact member between the contact positions and the non-contact positions.
