A system for electrically coupling modular electrical devices, the system comprising: a first modular electronic device adapted to be mechanically coupled to a second modular electronic device, the first modular electronic device including a first housing and a first circuit board within the first housing, the first circuit board including a first electrical connector electrically coupled to the circuit board; the second modular electronic device including a second housing and a second circuit board and a flexible circuit element within the second housing, the second circuit board electrically coupled to the flexible circuit element, the second housing including a latch plate adjustable between an unlatched position and a latched position, the latch plate including a biasing member; the flexible circuit element being electrically coupled to a second electrical connector, the second electrical connector adapted to electrically mate with the first electrical connector; and a connector carrier coupled to the second electrical connector, the connector carrier including a cam, the cam adapted to engage the biasing member when the latch plate is adjusted between the unlatched position and the latched position, such that, when the first modular electronic device is pressed together with the second modular electronic device, the biasing member applies a force to the cam during a latch plate transition position to ensure that the second electrical connector has fully mated with the first electrical connector, characterized in that both the cam and the connector carrier are further adapted to disengage completely from the biasing member when the latch plate is in the latched position, causing a gap to be present between the second housing and the connector carrier, and a gap between the biasing member and the connector carrier to provide mechanical isolation of the second electrical connector from the second modular electronic device. a first modular electronic device adapted to be mechanically coupled to a second modular electronic device, the first modular electronic device including a first housing and a first circuit board within the first housing, the first circuit board including a first electrical connector electrically coupled to the circuit board; the second modular electronic device including a second housing and a second circuit board and a flexible circuit element within the second housing, the second circuit board electrically coupled to the flexible circuit element, the second housing including a latch plate adjustable between an unlatched position and a latched position, the latch plate including a biasing member; the flexible circuit element being electrically coupled to a second electrical connector, the second electrical connector adapted to electrically mate with the first electrical connector; and a connector carrier coupled to the second electrical connector, the connector carrier including a cam, the cam adapted to engage the biasing member when the latch plate is adjusted between the unlatched position and the latched position, such that, when the first modular electronic device is pressed together with the second modular electronic device, the biasing member applies a force to the cam during a latch plate transition position to ensure that the second electrical connector has fully mated with the first electrical connector, characterized in that both the cam and the connector carrier are further adapted to disengage completely from the biasing member when the latch plate is in the latched position, causing a gap to be present between the second housing and the connector carrier, and a gap between the biasing member and the connector carrier to provide mechanical isolation of the second electrical connector from the second modular electronic device.
