A plug connector for plugging onto or into a counterpart plug connector, having at least two counterpart contact elements, in a plugging direction. The plug connector has a housing having a first plane that faces in the plugging direction. The housing has at least two contact chambers, each of which has an opening in the first plane. At least two of the contact chambers in the housing are embodied separately from one another. A wall, which protrudes from the first plane when viewed oppositely from the plugging direction, is disposed between at least two mutually adjacent contact chambers. Alternatively or additionally, at least one groove is disposed in the first plane between at least two mutually adjacent contact chambers.

A movable support structure, wherein the retaining/restricting portion is resiliently deformable in a direction to be retracted from a relative passage path for the receiving portion when the supported portion is inserted into the movable supporting portion from a catching posture, in which the retaining/restricting portion is caught by the receiving portion, with the supported portion supported by the movable supporting portion, and the deformation restricting portion restricts resilient deformation of the retaining/restricting portion in a direction to be retracted from the catching posture.

A connector includes a first and second connector housings, a first and second terminals provided in the first and second connector housings, the second terminal including contact pieces with a gap therebetween, the gap being larger than a width dimension of the first terminal. The second connector housing includes pressing plate portions. The second terminal is to be accommodated between the pressing plate portions, the second terminal being displaceable between a first position and a second position, a part of the contact pieces extends beyond distal ends of the pressing plate portions when the second terminal is in the first position, the part of the contact pieces are completely retracted into a space between the pressing plate portions when the second terminal is in the second position. The contact pieces are to be pushed such that the contact pieces contact the terminal plate portions.

A switch assembly including a switch and a connector, the switch and the connector being configured to interlock, and the switch includes a connection extending at least partially along a center axis of the switch, the connection being configured to receive at least a part of the connector.
